Instructions for use CICLOSPORIN HEXAL

Pharmacological properties of the drug Cyclosporine

Immunosuppressive agent; a cyclic polypeptide consisting of 11 amino acids. Suppresses the development of cell-type reactions, including immunity to the allograft, delayed-type skin allergic reaction, graft-versus-host reaction, allergic encephalomyelitis, arthritis caused by Freund's adjuvant, as well as T-lymphocyte-dependent antibody formation. At the cellular level, it blocks resting lymphocytes that are in the G0 or G1 phases of the cell cycle and suppresses the antigen-induced production and secretion of lymphokines (including interleukin-2 - T-lymphocyte growth factor) by activated T-lymphocytes. Cyclosporine appears to have a reversible effect on lymphocytes. Unlike cytostatics, it does not suppress hematopoiesis and does not affect the function of phagocytes. After oral administration, maximum plasma concentrations are achieved within 1–5 hours. Cyclosporine is distributed mainly outside the bloodstream; blood plasma contains 33-47%, lymphocytes - 4-9%, granulocytes - 5-12% and erythrocytes - 41-58%. In blood plasma, approximately 90% of cyclosporine is bound to proteins, mainly lipoproteins. Cyclosporine undergoes biotransformation, including various reactions, resulting in the formation of about 15 metabolites. Excretion from the body occurs mainly in bile and only 6% of the dose in urine (mainly in the form of metabolites). The half-life ranges from 6.3 hours in healthy individuals to 20.4 hours in patients with severe liver disease.

Pharmacological properties.
Pharmacodynamics.
Cyclosporine is a cyclic polypeptide consisting of 11 amino acids. Cyclosporine is a selective immunosuppressant that inhibits calcium neuron activation of lymphocytes in the G0 or G1 phase of the cell cycle. Thus, T-lymphocyte activation and, at the cellular level, antigen-dependent release of lymphokines, including interleukin 2 (T-lymphocyte growth factor), are prevented. Cyclosporine acts specifically and reversibly on lymphocytes. Unlike cytostatics, it does not suppress hematopoiesis and does not affect the function of phagocytes.

Cyclosporine increases the lifespan of allogeneic transplants of skin, heart, kidneys, pancreas, bone marrow, small intestine, and lungs. Cyclosporine also inhibits the development of cellular reactions against the allograft, delayed-type hypersensitivity skin reactions, experimental allergic encephalomyelitis, arthritis due to Freund's adjuvant, graft-versus-host disease (GVHD), and T-lymphocyte-dependent antibody formation. Sandimmune has been shown to be effective in human bone marrow and solid organ transplantation for the prevention and treatment of rejection and GVHD, as well as in the treatment of various conditions that are or may be considered autoimmune in nature.

Pharmacokinetics

. Cyclosporine is distributed mainly outside the bloodstream. In the blood, 33-47% of cyclosporine is found in plasma, 4-9% in lymphocytes, 5-12% in granulocytes and 41-58% in erythrocytes. Binding to plasma proteins (mainly lipoproteins) is approximately 90%.

Cyclosporine undergoes significant biotransformation in the liver by hydroxylation, resulting in the formation of approximately 15 metabolites. There is no one main metabolic pathway. The drug is excreted primarily in bile and only 6% of the administered oral dose is excreted in the urine (less than 1% is excreted unchanged).

The terminal half-life of cyclosporine is highly variable, depending on the determination method used and the patient population studied. The terminal half-life with unchanged liver function is approximately 6.3 hours; in patients with severe liver disease - approximately 20.4 hours.

Pharmacokinetics in special groups of patients.

Patients with impaired renal function. In patients with end-stage renal failure, after intravenous administration of the drug at a dose of 3.5 mg/kg over 4 hours, mean peak blood concentrations of cyclosporine were approximately 1800 ng/ml (range 1536 to 2331 ng/ml). The mean volume of distribution was 3.49 L/kg and systemic clearance was 0.369 L/h/kg, which is approximately two-thirds of the mean systemic clearance (0.56 L/h/kg) in patients with normal renal function. Impaired renal function does not have a significant effect on the elimination of cyclosporine, since cyclosporine is excreted mainly in bile through the intestines.

Patients with impaired liver function.

In patients with biopsy-proven cirrhosis and severe liver dysfunction, the half-life of the drug averaged 20.4 hours (range 10.8 to 48.0 hours) compared with 7.4 to 11.0 hours in healthy subjects.

Indications for use.

Solid organ transplantation:

• prevention of rejection of allografts: kidney, liver, heart, combined cardiopulmonary transplant, lungs or pancreas (in cases where oral administration of the drug is impossible, or absorption of the drug when administered orally is impaired due to diseases of the gastrointestinal tract (GIT));

• prevention of transplant rejection in patients who have previously received other immunosuppressive therapy.

Bone marrow transplantation:

• prevention of graft rejection after bone marrow transplantation;

• prevention and treatment of graft-versus-host disease (GVHD) (in cases where oral administration of the drug is impossible, or absorption of the drug when taken orally is impaired due to gastrointestinal diseases).

Contraindications

. Hypersensitivity to cyclosporine or any other component of the drug, including polyoxyethylene castor oil.

Carefully.

Sandimmun® should be prescribed with caution to patients aged > 65 years, patients with hyperlipidemia, hyperkalemia, hypomagnesemia and hyperuricemia, impaired liver function, arterial hypertension, as well as epilepsy, alcoholism.

Use during pregnancy, breastfeeding and in women of childbearing age.

No special recommendations have been developed for women of childbearing age. The amount of data on the effect of the drug on fertility is limited. In experimental studies of the pathological effects of the drug

no effect on fertility was detected. Experimental studies have shown the toxic effect of the drug on reproductive function. There is little data on the use of Sandimmune® in pregnant women. Pregnant women who have undergone organ transplantation and are receiving immunosuppressive treatment with cyclosporine or combination therapy that includes cyclosporine are at risk of preterm birth (occurring before 37 weeks' gestation). There is a limited number of observations of children (up to the age of 7 years) exposed to cyclosporine during fetal development. Kidney function and blood pressure were normal in these children. However, since there is not enough reliable data on the use of the drug in pregnant women, Sandimmun® should not be used during pregnancy, unless the expected benefit to the mother justifies the potential risk to the fetus. In pregnant women, it is also necessary to take into account the ethanol content of the drug.

Cyclosporine passes into breast milk. Mothers receiving Sandimmune® should not breastfeed. Due to the risk of severe adverse reactions in newborns whose mothers are taking Sandimmun®, it is necessary to either refrain from breastfeeding or from taking the drug, taking into account how important drug therapy is for the mother. It is also necessary to remember the ethanol content in the preparation.

Method of administration and dose.

The drug is administered intravenously (IV) by drip.

The dosage regimen is set individually. The choice of the initial dose, as well as the correction of the dosage regimen during treatment, is carried out taking into account clinical and laboratory parameters, as well as the values ​​of the concentration of cyclosporine in the blood plasma, determined daily.

For adults undergoing a bone marrow transplant on the day before the transplant, Sandimmune is administered intravenously at a dose of 3-5 mg/kg/day. Administration of this dose is continued during the immediate post-transplant period for up to 2 weeks; then switch to maintenance therapy with oral forms of cyclosporine. In cases where drug absorption is impaired, it may be necessary to continue intravenous administration. Some patients may develop GVHD after discontinuation of cyclosporine therapy, the manifestations of which are usually well controlled when the drug is resumed. In such cases, an initial loading dose of the drug taken orally equal to 10-12.5 mg/kg body weight is prescribed, followed by its subsequent reduction to a maintenance, previously effective dose. Low doses of cyclosporine should be used to treat moderate manifestations of chronic GVHD. For solid organ transplantation, Sandimmune® concentrate for intravenous infusion is prescribed 12 hours before surgery, in a single dose of 3-5 mg/kg body weight. For 1-2 weeks after surgery, the drug is prescribed daily at the same dose, after which the dose is gradually reduced, under the control of the concentration of cyclosporine in the blood, to a maintenance dose of 0.7-2 mg/kg body weight in 2 doses.

When Sandimmune is prescribed in combination with glucocorticosteroids or other immunosuppressants, smaller doses of Sandimmune can be used.

Use in special groups of patients. Use in patients with impaired renal function.

The drug is almost not excreted by the kidneys and its pharmacokinetics does not depend on renal function. However, given the nephrotoxicity of cyclosporine, renal function should be monitored.

Use in patients with impaired liver function.

The drug is actively metabolized in the liver. The half-life ranges from 6.3 hours in healthy volunteers to 12.4 hours in patients with severe liver disease. To maintain the recommended blood concentration of cyclosporine in patients with severe liver dysfunction, a dose reduction may be required.

Use in children

.

Experience in children is limited. Children over 1 year of age who received standard doses of the drug tolerated the therapy well. According to several studies, children tolerated well even higher doses of mg/kg/day than those indicated for adults. In pediatric practice, Sandimmune is used at a dose of 3-5 mg/kg/day; The dosage regimen is the same as for adult patients.

Use in elderly patients

(>65 years). Experience with the use of Sandimmune in elderly patients is limited. elderly patients is limited, however, the use of standard adult doses of the drug is usually well tolerated.

In clinical studies studying the use of the drug Sandimmune® in patients with rheumatoid arthritis, it was noted that patients over 65 years of age were more likely to experience episodes of systolic arterial hypertension, in addition, they were more likely to have an increase in plasma creatinine concentration (>50%) after 3 -4 months of taking the drug.

According to other studies, the tolerability of cyclosporine does not differ between older and younger patients.

In elderly patients, it is recommended to use Sandimmune® with caution, choosing the lower limit of the dosage range, taking into account the higher risk of developing liver, kidney, and heart failure in these patients, as well as the higher likelihood of concomitant diseases and corresponding concomitant therapy.

Rules for the preparation and administration of infusion solution.

The concentrate should be diluted in a ratio of 1:20-1:100 with a 0.9% sodium chloride solution or a 5% dextrose solution and administered over approximately 2-6 hours. The unused prepared solution should be discarded after 24 hours. It is advisable to use glass containers to prepare the infusion solution. Plastic vials may only be used if they comply with the requirements for “plastic blood containers” of the European Pharmacopoeia. Polyoxyethylene castor oil contained in the concentrate may cause phthalate release from the polyvinyl chloride. Containers and their stoppers must not contain silicone oil or fatty components.

Side effect

.

The main adverse events associated with the drug and observed in clinical studies are impaired renal function, tremor, hirsutism, increased blood pressure, diarrhea, anorexia, nausea and vomiting. Many side effects associated with cyclosporine are dose-dependent and reversible with dose reduction. The spectrum of side effects is generally the same across different indications, although the frequency and severity of side effects may vary. In transplant patients, due to the higher dose and longer duration of treatment, side effects are more common and usually more severe than in patients with other indications.

Cases of anaphylactoid reactions have been reported with intravenous administration of cyclosporine.

In patients receiving immunosuppressive treatment with cyclosporine or combination therapy including cyclosporine, the risk of developing local and generalized infections (viral, bacterial, fungal etiology) and parasitic infestations increases. It is also possible to exacerbate pre-existing infectious diseases and reactivate a polyomavirus infection, leading to the development of polyomavirus nephropathy or JCvirus, which contributes to the development of multifocal leukoencephalopathy. Severe and/or fatal outcomes have been reported.

Patients receiving immunosuppressive treatment with cyclosporine or combination therapy that includes cyclosporine have an increased risk of developing lymphomas, lymphoproliferative diseases and malignancies, especially of the skin. The incidence of malignant neoplasms increases with increasing intensity and duration of immunosuppressive therapy.

The incidence of adverse events was assessed as follows: occurring “very often” (≥1/10), “often” (≥1/100; <1/10), “occasionally” (≥1/1000; <1/100), "rarely"; (≥1/10000; <1/1000), “very rare”; (<1/10000), including individual messages.

Description of some adverse events.

Hepatotoxicity and liver damage.

In post-marketing surveillance, there have been isolated case reports of cyclosporine hepatotoxicity and liver injury resulting in cholestasis, jaundice, hepatitis and liver failure. In most cases, reports concerned patients with severe concomitant diseases and other predisposing factors, such as infectious complications, concomitant use of drugs that have a hepatotoxic effect. In some cases, mainly in transplant patients, these side effects have been fatal.

Acute and chronic nephrotoxicity.

Patients treated with calcineurin inhibitors (CNIs), including cyclosporine, and treatment regimens containing cyclosporine are at increased risk of acute or chronic nephrotoxicity. Clinical studies and post-marketing surveillance data indicate that cases of acute nephrotoxicity were associated with hyperkalemia, hypomagnesemia and hyperuricemia. In cases of chronic nephrotoxicity reported, morphological signs of arteriolar hyalinosis, tubular atrophy and interstitial fibrosis were noted.

If any of the side effects indicated in the instructions get worse, or you notice any other side effects not listed in the instructions, tell your doctor.

Overdose.
Symptoms:
Available experience with acute overdoses of cyclosporine is limited.
When cyclosporine was taken orally at a dose of up to 10 g (about 150 mg/kg), in most cases mild clinical manifestations were observed, such as vomiting, dizziness, headache, and tachycardia. In some cases, reversible impairment of moderate renal function was observed. However, with accidental parenteral overdose of cyclosporine in premature infants in the neonatal period, the development of severe toxic complications has been reported. Treatment:
symptomatic therapy, there is no specific antidote. During the first 2 hours after oral administration, the drug can be removed from the body by inducing vomiting or by gastric lavage. Cyclosporine is practically not excreted during hemodialysis and hemoperfusion using activated charcoal.

Drug interactions and other forms of interaction.
Interaction with drugs
. Listed below are drugs for which interaction with cyclosporine is confirmed and clinically significant.

Combinations with cyclosporine not recommended for use.

Vaccinations may be less effective during treatment with cyclosporine. The use of live attenuated vaccines should be avoided.

Combinations with cyclosporine requiring caution.

Caution should be exercised when using cyclosporine together with potassium-sparing drugs (potassium-sparing diuretics, ACE inhibitors, angiotensin II receptor antagonists) or drugs containing potassium, as when used simultaneously with cyclosporine, severe hyperkalemia may develop.

With simultaneous use of cyclosporine and lercanidipine, there is an increase in lercanidipine AUC by 3 times and an increase in cyclosporine AUC by 21%. Caution should be exercised when using cyclosporine and lercanidipine in combination. Cyclosporine is a highly active P-glycoprotein (Pgp) inhibitor. As a result, when administered concomitantly, it may increase the serum concentrations of drugs that are Pgp substrates, such as aliskiren. When iclosporin and aliskiren are taken together, the Cmax of aliskiren increases by approximately 2.5 times, and the aAUC of aliskiren increases by 5 times. However, the pharmacokinetics of cyclosporine does not change significantly. Therefore, caution should be exercised when cyclosporine and aliskiren are used in combination.

Drugs that reduce or increase the concentration of cyclosporine.

Various agents are known to decrease and increase cyclosporine plasma or whole blood levels by inhibiting or inducing isoenzymes involved in cyclosporine metabolism, particularly CYP3A4. If such interactions in post-transplant patients cannot be avoided, frequent regular monitoring of cyclosporine concentrations and, if necessary, correction are necessary, which is especially important when prescribing or discontinuing a drug that interacts with cyclosporine.

Drugs that reduce the concentration of cyclosporine: barbiturates, carbamazepine, oxcarbazepine, phenytoin; nafcillin, sulfadimidine when administered intravenously; rifampicin; octreotide; probucol; orlistat; preparations containing St. John's wort (Hypericumperforatum); ticlopidine, terbinafine, sulfinpyrazone, bosentan.

Drugs that increase the concentration of cyclosporine:

macrolide antibiotics (eg, erythromycin, azithromycin and clarithromycin); ketoconazole, fluconazole, itraconazole, voriconazole; diltiazem, nicardipine, verapamil; metoclopramide; oral contraceptives; danazol; methylprednisolone (high doses); allopurinol; amiodarone; cholic acid and its derivatives; protease inhibitors, imatinib, colchicine, nefadazone.

Other significant interactions.

Food interactions.

There are reports that grapefruit juice increases the bioavailability of cyclosporine.
Interactions leading to potential increased nephrotoxicity.
When used simultaneously with drugs that increase the nephrotoxicity of cyclosporine, regular monitoring of renal function (especially plasma creatinine concentrations) is necessary. If significant renal impairment is detected, it is necessary to adjust the dose of the drug combined with cyclosporine or prescribe alternative therapy. Nonsteroidal anti-inflammatory drugs with a pronounced first-pass effect through the liver (for example, diclofenac) should be prescribed in lower doses than in patients not receiving cyclosporine. There are isolated reports that post-transplant patients experienced severe but transient renal dysfunction (with increased plasma creatinine concentrations) when fibric acid derivatives (eg, fenofibrates, bezofibrates) were used concomitantly with cyclosporine. In these patients, constant monitoring of renal function is necessary. In case of significant deterioration, combined use should be discontinued.

Interactions leading to gingival hyperplasia.

The combined use of nifedipine and cyclosporine may lead to more severe gingival hyperplasia than with cyclosporine monotherapy. Nifedipine should be avoided in patients who have developed gingival hyperplasia as a side effect of cyclosporine therapy.

Combinations that increase the concentration of other drugs.

Since cyclosporine is an inhibitor of the CYP3A4 isoenzyme and the membrane transporter of P-glycoprotein molecules, when used simultaneously with it, it is possible to increase the concentration of drugs that are substrates of the CYP3A4 isoenzyme and/or the membrane transporter of P-glycoprotein. Cyclosporine may reduce the clearance of digoxin, colchicine, prednisolone, HMG-CoA reductase inhibitors (statins) and etoposide.

Several cases of severe glycoside toxicity have been reported within a few days of starting cyclosporine treatment in patients receiving digoxin. There are also reports that cyclosporine may enhance the toxic effects of colchicine, such as the development of myopathy or neuropathy, especially in patients with impaired renal function. When cyclosporine is used concomitantly with digoxin or colchicine, careful clinical monitoring is necessary to promptly identify the toxic effects of these drugs and to decide whether to reduce the dose or discontinue treatment.

When using cyclosporine in clinical practice, as well as according to the literature, cases of muscle toxicity, including muscle pain, weakness, myositis and rhabdomyolysis, have been reported during the simultaneous use of cyclosporine with lovastatin, simvastatin, atorvastatin, pravastatin and, in rare cases, with fluvastatin . If it is necessary to use the above drugs simultaneously with cyclosporine, it is necessary to reduce their dose. Statin therapy should be temporarily discontinued or discontinued in patients with symptoms of myopathy, as well as in patients with predisposition factors for severe renal impairment, including renal failure secondary to rhabdomyolysis. If digoxin, colchicine, HMG-CoA reductase inhibitors (statins) must be taken together with cyclosporine, patients should be carefully examined for the earliest possible detection of toxic effects of the drugs, which will require a dose reduction or discontinuation of the drugs.

An increase in creatinine concentrations was observed in studies that examined the coadministration of everolimus or sirolimus with high-dose cyclosporine microemulsion. This effect is often reversible after reducing the dose of cyclosporine. Everolimus and sirolimus have little effect on the pharmacokinetic parameters of cyclosporine. The combined use of cyclosporine with everolimus or sirolimus leads to a significant increase in the concentration of the latter in the blood plasma.

Concomitant use of cyclosporine and bosentan in healthy volunteers resulted in a twofold increase in bosentan exposure and a 35% decrease in cyclosporine exposure. Long-term concomitant use of ambrisentan and cyclosporine in healthy volunteers caused a twofold increase in ambrisentan exposure, while cyclosporine exposure increased slightly (by 10%). Significantly increased exposure to anthracycline antibiotics (eg, doxorubicin, mitoxantrone, daunorubicin) in patients with cancer receiving intravenous anthracycline antibiotics and very high doses of cyclosporine.

Special instructions.

Sandimmune should only be used by physicians experienced in administering immunosuppressive therapy and able to provide adequate patient monitoring, including regular complete physical examination, blood pressure measurement, and serum creatinine concentration monitoring. Monitoring of transplant patients receiving the drug should be carried out only in institutions that have trained medical personnel and adequate laboratory resources.

It should be borne in mind that when using cyclosporine, as well as other immunosuppressants, the risk of developing lymphomas and other malignant neoplasms, most often of the skin, increases. The increased risk of developing this complication is related more to the strength and duration of immunosuppression than to the use of a specific drug. Therefore, caution should be exercised when using combination immunosuppressive regimens, keeping in mind the potential for the development of lymphoproliferative diseases and solid organ tumors, sometimes leading to death.

Given the potential risk of developing skin malignancies, patients receiving cyclosporine treatment should avoid excessive exposure to direct sunlight.

The use of cyclosporine, like other immunosuppressants, predisposes to the development of various bacterial, fungal, parasitic and viral infections, often involving opportunistic pathogens. In patients treated with cyclosporine, reactivation of polyomavirus infection from a latent state was observed, leading to the development of polyomavirus nephropathy (especially associated with BK virus) or multifocal leukoencephalopathy caused by JC virus. These conditions are caused by a high overall load of immunosuppressive drugs. The development of such conditions should be taken into account in the differential diagnosis of the causes of renal and nervous system dysfunction in patients receiving immunosuppressive therapy.

Considering the potential danger of these infections for the patient’s life, an effective system of preventive and therapeutic measures should be used, especially in cases of long-term use of combined immunosuppressive treatment.

During the first few weeks of Sandimmune therapy, a common and potentially dangerous complication may occur: increased serum creatinine and urea levels. These functional changes are reversible and dose-dependent, normalizing with dose reduction. With long-term treatment, some patients may develop structural changes in the kidneys (for example, interstitial fibrosis), which in patients with renal transplants should be differentiated from changes due to chronic rejection.

Sandimmune may also cause a dose-dependent, reversible increase in serum bilirubin and, rarely, liver enzymes. In these cases, careful monitoring of renal and liver function parameters is required. If these indicators deviate from the norm, a dose reduction may be required.

In elderly patients, renal function should be especially carefully monitored.

Measuring the concentration of cyclosporine in the blood.

Routine monitoring of cyclosporine blood levels is an important safety monitoring mechanism. To monitor the concentration of cyclosporine in whole blood, it is preferable to use specific monoclonal antibodies (measurement of the amount of unchanged drug).

A high-performance liquid chromatography (HPLC) method can be used, which also measures the unchanged substance content. If plasma or serum is used, standard separation procedures (time and temperature) should be followed. For initial monitoring of cyclosporine concentrations in liver transplant patients, both specific monoclonal antibodies and parallel determinations using specific and nonspecific monoclonal antibodies should be used to achieve a dose that provides adequate immunosuppression.

It should be remembered that the concentration of cyclosporine in whole blood plasma or serum is only one of many factors characterizing the clinical condition of the patient. The results of determining the concentration of cyclosporine are only one of the factors determining the dosage regimen, and are considered in relation to various clinical and laboratory indicators. Blood pressure (BP) control.

During treatment with Sandimmune, regular blood pressure monitoring is indicated; if blood pressure increases, adequate antihypertensive therapy should be prescribed. Preference should be given to antihypertensive drugs that do not affect the pharmacokinetics of cyclosporine, such as isradipine.

Since in rare cases Sandimmune causes minor reversible hyperlipidemia, it is recommended to determine blood lipid concentrations before treatment and one month after the start of therapy. If lipid concentrations increase, consideration should be given to limiting dietary fat intake and, if necessary, reducing the dose of Sandimmune.

Cyclosporine increases the risk of hyperkalemia, especially in patients with impaired renal function. Caution should also be exercised when cyclosporine is used concomitantly with potassium-sparing diuretics, ACE inhibitors, angiotensin II receptor antagonists and potassium-containing drugs, as well as when using a potassium-enriched diet. In these cases, monitoring the concentration of potassium in the blood is recommended.

Cyclosporine increases the excretion of magnesium from the body, which can lead to clinically significant hypomagnesemia, especially in the peritransplant period. In this regard, it is recommended to monitor the concentration of magnesium in the blood during the peritransplantation period, especially when neurological symptoms appear. If necessary, magnesium supplements are prescribed.

It is recommended to monitor serum uric acid concentrations, especially in patients with pre-existing hyperuricemia.

Live attenuated vaccines.

During treatment with Sandimmune®, vaccination may be less effective. The use of live attenuated vaccines should be avoided.

Ethanol.

When using the drug Sandimmune® in pregnant and lactating women, in patients with liver diseases, epilepsy, alcoholism, as well as in children, it is necessary to remember the ethanol content of the drug.

Impact on the ability to perform potentially hazardous activities that require increased attention and quick reactions (driving a car, working with moving mechanisms, etc.)

Some side effects of Sandimmun®, including dizziness or visual disturbances, may adversely affect the ability to drive vehicles and perform potentially hazardous activities that require increased concentration and speed of psychomotor reactions.

Use of the drug Cyclosporine

The dose is set individually. The choice of the initial dose and correction of the dosage regimen during treatment is carried out depending on the data of clinical and laboratory studies, as well as on the level of cyclosporine concentration in the blood plasma, which is determined daily. For adults undergoing solid organ transplantation, treatment with cyclosporine should begin at a dose of 10–15 mg/kg (divided into 2 doses) 12 hours before surgery. For 1–2 weeks after surgery, the same dose is prescribed daily, after which the dose is gradually reduced (under the control of the concentration of cyclosporine in the blood) until a maintenance dose of 2–6 mg/kg/day is reached. When cyclosporine is prescribed in combination with GCS or other immunosuppressants at the beginning of treatment, its dose can be reduced to 3-6 mg/kg. When undergoing a bone marrow transplant, cyclosporine is prescribed on the day before the transplant and during the transplantation period for at least 2 weeks orally at a daily dose of 12.5–15 mg/kg, then switch to maintenance therapy at a dose of about 12.5 mg/kg/ day Cyclosporine can be administered intravenously at a dose of 3–5 mg/kg/day. Administration of this dose is continued immediately during the post-transplant period (up to 2 weeks), then they switch to maintenance therapy with oral forms of the drug. Maintenance treatment is continued for at least 3–6 months, after which the dose is gradually reduced so that treatment is discontinued 1 year after transplantation. In some patients, after stopping treatment with the drug, graft-versus-host disease may develop. In this case, treatment should be resumed. In case of chronic mild graft-versus-host disease, low doses of cyclosporine should be used. Children over 1 year of age are prescribed in the same doses as adults (per 1 kg of body weight). For endogenous uveitis, to induce remission, an initial daily dose of 5 mg/kg orally in 1 or several doses is prescribed until the severity of inflammation decreases and visual acuity improves. In severe cases, the dose can be increased to 7 mg/kg/day for a limited period (if the desired effect cannot be achieved, systemic prednisolone can be additionally prescribed at a daily dose of 200–600 mcg/kg). During maintenance therapy, the dose should be slowly reduced until the minimum effective dose is reached, which during the period of remission of the disease should not exceed 5 mg/kg/day. In nephrotic syndrome, to induce remission, cyclosporine is prescribed in a daily dose of 5 mg/kg for adults and 6 mg/kg for children (in 2 doses) with normal renal function (except in cases of proteinuria). For patients with impaired renal function, the initial daily dose should not exceed 2.5 mg/kg. If monotherapy with cyclosporine fails to achieve the desired effect, especially in patients with resistance to GCS, it is possible to combine cyclosporine with oral GCS in low doses. If after 3 months of treatment a positive effect cannot be achieved, therapy should be discontinued. For maintenance treatment, the dose should be slowly reduced to the minimum effective dose. For rheumatoid arthritis, during the first 6 weeks of treatment, the daily dose is 3 mg/kg in 2 divided doses. In case of insufficient effect, the daily dose can be gradually increased subject to satisfactory tolerability, but it should not exceed 5 mg/kg/day. The course of treatment is up to 12 weeks. For psoriasis, to induce remission, the daily dose is 2.5 mg/kg in 2 divided doses. In severe cases of the disease, when it is necessary to achieve a rapid effect, the initial daily dose may be 5 mg/kg. If after 1 month of treatment the desired result is not observed, the daily dose can be gradually increased, but it should not exceed 5 mg/kg. If it is not possible to achieve an adequate clinical effect when using cyclosporine at a daily dose of 5 mg/kg for 6 weeks, treatment should be discontinued. The dose for maintenance treatment of patients with psoriasis should be minimally effective (not higher than 5 mg/kg/day). For atopic dermatitis, an initial dose of 2.5 mg/kg/day is recommended. In severe cases, the dose can be increased to 5 mg/kg/day. When a positive clinical result is achieved, the dose should be gradually reduced until completely discontinued.

Pharmacodynamics

Means for use in ophthalmology. Cyclosporine is a substance that has an immunosuppressive effect when administered systemically. With the predicted inhibition of tear fluid production in patients with keratoconjunctivitis sicca, it is believed that cyclosporine, when applied topically (in the form of an emulsion), partially acts as an immunomodulator. The exact mechanism of action has not been established. A statistically significant increase in the functional parameters of the lacrimal gland was indicated. There was no increase in the severity of inflammatory eye diseases of a bacterial or fungal nature with topical use of cyclosporine.

Pharmacokinetics

The concentration of cyclosporine in all collected blood samples after topical administration in adults at a concentration of 500 μg/ml2 for up to 12 months was below the detectable level - 0.1 ng/ml. There was no accumulation of cyclosporine in the blood during treatment lasting 12 months by topical application in the form of an ophthalmic emulsion.

Use during pregnancy

There have been no studies of cyclosporine administered topically in pregnant women. It is known that cyclosporine is excreted in breast milk when the drug is administered systemically. Excretion into breast milk following topical use has not been studied.

Contraindications for use

Hypersensitivity (including to polyoxyethylene castor oil), malignant neoplasms, severe infectious diseases, renal and/or liver dysfunction, arterial hypertension, hyperuricemia, hyperkalemia, pregnancy, breastfeeding.

Side effects

Acute and chronic renal failure, interstitial fibrosis of the kidneys, arterial hypertension, tremor, weakness, headache, paresthesia, seizures, myopathy, liver dysfunction, pancreatitis, nausea, vomiting, anorexia, abdominal pain, feeling of heaviness in the epigastric region, diarrhea , gum hyperplasia, fluid retention in the body, reversible dysmenorrhea and amenorrhea, hypertrichosis, thrombocytopenia, anemia, hyperkalemia, hyperuricemia, increased susceptibility to infections.

Directions for use and doses

1 drop of ophthalmic emulsion 2 is instilled into the conjunctival sac with an interval of 12 hours.

Interactions with other drugs

There are no interaction data with cyclosporine in the form of ophthalmic emulsion. But when using an ophthalmic emulsion, the interaction characteristic of cyclosporine when used systemically cannot be excluded. Aminoglycoside antibiotics, amphotericin B, ketoconazole, trimethoprim, melphalan, ciprofloxacin, colchicine, cephalosporin antibiotics, NSAIDs and ACE inhibitors, cimetidine, ranitidine, tacrolimus can increase the nephrotoxicity of cyclosporine. Quinidine and its derivatives, theophylline and its derivatives, sodium valproate and its derivatives enhance the effect of cyclosporine. Drugs that increase the concentration of cyclosporine in the blood due to inhibition of enzymes (mainly cytochrome CYP3A) that are involved in its metabolism and excretion: oral contraceptives, corticosteroids, macrolide antibiotics (erythromycin, josamycin, clarithromycin), antifungal agents imidazole and triazole derivatives (metronidazole, fluconazole, itraconazole, ketoconazole), histamine H2 receptor antagonists (ranitidine, cimetidine), calcium channel blockers (diltiazem, nifedipine, nimodipine, nicardipine, verapamil), fluoroquinolones, pristinamycin, doxycycline, propafenone, allopurinol, bromocriptine, danazol, metoclopramide. With the simultaneous use of these drugs and cyclosporine, an increase in the frequency of side effects, primarily nephrotoxicity, is noted. Drugs that reduce the concentration of cyclosporine in the blood due to the induction of enzymes, primarily cytochrome CYP3A, which are responsible for the metabolism and excretion of cyclosporine: anticonvulsants (phenytoin, carbamazepine), barbiturates, benzodiazepines, butyrophenone and its derivatives, gestagens and estrogens, including their combinations, octreotide, ticlopidine, aminoglutethimide, phenothiazine, rifampicin, isoniazid, metamizole, trimethoprim and sulfamidine (iv), as well as St. John's wort preparations. When using these drugs and cyclosporine simultaneously, caution and frequent monitoring of the concentration of cyclosporine in the blood and serum creatinine levels are required. With simultaneous use of cyclosporine with colchicine and lovastatin, the risk of developing myopathy increases. If muscle pain or muscle weakness occurs with the combined use of these drugs, it is necessary to determine the level of CPK, since there is a risk of developing rhabdomyolysis and acute renal failure. Given that nifedipine can cause the development of gingival hypertrophy, it should not be used in patients whose gums were affected during treatment with cyclosporine. When treated with cyclosporine, the effectiveness of vaccination may be reduced. Therefore, when treating with cyclosporine ophthalmic emulsion, the use of live attenuated vaccines should be avoided. Cyclosporine sometimes causes hyperkalemia or exacerbation of existing hyperkalemia, so when used concomitantly with drugs that contain potassium or drugs that increase serum potassium levels, there is a risk of developing hyperkalemia. It is recommended to monitor serum potassium levels, especially in patients with significant impairment of renal function. When using cyclosporine concomitantly with the imipenem/cilastatin combination, it is necessary to take into account the increased concentration of cyclosporine, which causes the development of symptoms of neurotoxicity (confusion, tremors, agitation). Therefore, with this combination, the concentration of cyclosporine in the blood plasma should be monitored more often, as well as the general condition of the patient should be monitored in order to prevent possible disorders of the central nervous system. With the simultaneous use of cyclosporine and other immunosuppressive drugs, the risk of developing infectious and lymphoproliferative diseases increases. Therefore, cyclosporine should not be used concomitantly with these drugs, with the exception of corticoids (low dose prednisone) and azathioprine. In this case, it is necessary to reduce the dose of cyclosporine accordingly. If a combination of all three drugs is used, the patient's condition should be monitored taking into account the above-mentioned risks. The bioavailability of cyclosporine administered orally in children is significantly increased by concomitant use of cyclosporine and alpha-tocopheryl polyethylene glycol 100 (TRGS), a water-soluble form of vitamin E. Concomitant use of drugs that interact with the cytochrome P450 system may affect the metabolism of cyclosporine. Inducers of cytochrome P450 reduce the concentration of cyclosporine in the blood, while inhibitors of cytochrome P450 increase it. Grapefruit juice also affects the metabolism of cyclosporine, so its use is not recommended during treatment.

Precautions for use

Treatment should be carried out in a specialized hospital by doctors with sufficient experience in immunosuppressant therapy. It should be borne in mind that cyclosporine increases the susceptibility to lymphoproliferative malignancies, therefore, before prescribing it, it is necessary to decide how much the expected beneficial effect justifies the risk of undesirable effects. Use during pregnancy is permissible only under strict indications. Since there is a possibility of developing anaphylactoid reactions with intravenous administration, it is advisable to take prophylactic antihistamines and transfer the patient to oral medications as quickly as possible. It is recommended to select the dose depending on the content in the blood. After kidney transplantation, plasma levels are determined during the first 2 weeks 2 times a week, at 3-6 weeks - once a week, and during outpatient monitoring - once every 2-3 months. Regular monitoring of plasma creatinine concentration is necessary - an increase may indicate a rejection reaction, or a nephrotoxic effect and require (in the latter case) dose reduction: by 25% if creatinine increases by more than 30% from the original, and by 50% if its level doubles; when dose reduction within 4 weeks does not lead to a decrease in creatinine, cyclosporine is discontinued. Monitoring of blood pressure, blood levels of potassium, uric acid, bilirubin, transaminases, and lipid profile is recommended; immunization with live attenuated vaccines is contraindicated during the treatment period. When treating autoimmune diseases, the lack of adequate positive results after 3 months indicates the need to discontinue treatment.

Side effects of the drug Cyclosporine

On the part of the kidneys , renal dysfunction often develops, manifested by an increase in the concentration of creatinine and urea in the blood serum (usually these effects are observed during the first weeks of treatment, are dose-dependent and decrease with decreasing dose). With long-term treatment, some patients may develop structural changes in the kidneys (for example, interstitial fibrosis), which in patients with renal transplants should be differentiated from changes due to the development of a chronic rejection reaction. From the digestive tract and liver - anorexia, nausea, vomiting, diarrhea, abdominal pain, pancreatitis. Reversible liver function disorders are possible, manifested by an increase in the concentration of bilirubin and the activity of liver enzymes in the blood serum (the severity of these disorders is dose-dependent). From the cardiovascular system - hypertension (arterial hypertension) (especially in patients after heart transplantation). From the nervous system and skeletal muscles - possible headache, paresthesia, convulsions; rarely - muscle spasm, muscle weakness, myopathy, tremor. In patients after liver transplantation, signs of encephalopathy, impairment of vision, consciousness, and motor function have been described (however, it has not been conclusively established whether these changes are caused by the use of cyclosporine, the underlying disease, or other factors). From the endocrine system - reversible dysmenorrhea and amenorrhea. From the blood system - mild anemia. In rare cases, thrombocytopenia has developed due to microangiopathic hemolytic anemia and renal failure (hemolytic uremic syndrome). Allergic reactions - skin rash. Changes in laboratory parameters - hyperkalemia, hypomagnesemia, increased concentration of uric acid in the blood. Others - hypertrichosis, increased fatigue, gum hypertrophy; swelling, weight gain; rarely - reversible minor hyperlipidemia. There are isolated reports of the development of malignant and lymphoproliferative diseases during treatment with cyclosporine (as well as other drugs with an immunosuppressive effect), including in patients with nephrotic syndrome. There are reports of the development of malignant tumors (particularly of the skin) in patients with psoriasis.

Special instructions for the use of the drug Cyclosporine

Treatment with cyclosporine should only be administered by a physician experienced in immunosuppressive therapy and the management of patients after organ or bone marrow transplantation. Treatment is carried out only in specialized medical institutions. Caution should be exercised when prescribing cyclosporine to patients with impaired renal and/or liver function, hyperuricemia, and a tendency to develop hyperkalemia. Patients receiving treatment with cyclosporine are less susceptible to infections compared to those patients receiving other immunosuppressive therapy. Determination of the concentration of cyclosporine in the blood is carried out by radioimmunoassay using monoclonal antibodies or by high-performance liquid chromatography. In patients after liver transplantation, specific monoclonal antibodies should be used to determine the concentration of cyclosporine or parallel determination should be carried out using both specific and nonspecific monoclonal antibodies. During treatment with cyclosporine, systematic monitoring of blood pressure, the functional state of the kidneys and liver is indicated; determining the concentration of potassium in the blood plasma (especially in patients with impaired renal function), as well as determining the level of lipids in the blood serum (before the start of treatment and after the 1st month of treatment). If the increase in the concentration of urea, creatinine, bilirubin, and liver enzymes in the blood is persistent, the dose of cyclosporine should be reduced. In case of development of hypertension (arterial hypertension), it is necessary to begin antihypertensive treatment. If serum lipids increase, it is necessary to consider reducing the dose of the drug and/or prescribing an appropriate diet. Before prescribing cyclosporine for the treatment of autoimmune diseases, it is necessary to determine the initial level of creatinine in the blood serum (at least 2 studies). During treatment, systematic monitoring of serum creatinine concentration is necessary (preferably at intervals of 2 weeks during the first 3 months of treatment; thereafter - once every 1 or 2 months). The dose is adjusted taking into account changes in serum creatinine concentration. If there is an increase in serum creatinine concentration by more than 30% relative to the initial level, then a dose reduction of 25–50% is required. If the serum creatinine level increases by more than 50%, the dose should be reduced by 50%. These recommendations should be followed even if serum creatinine levels remain within the normal range. If dose reduction does not result in a decrease in serum creatinine concentration within a month, treatment with cyclosporine should be discontinued. Further use of cyclosporine is not indicated if hypertension (arterial hypertension) that developed during treatment remains refractory to adequate antihypertensive therapy. Cyclosporine can be prescribed to patients with endogenous uveitis only if renal function is initially normal. People with steroid-dependent minimal change nephropathy who have been treated for more than 1 year are advised to undergo a kidney biopsy. In patients with psoriasis, skin lesions that are not typical for psoriasis and if they are suspected of being malignant or precancerous should be biopsied before starting treatment with cyclosporine. Patients with cancerous or precancerous skin changes should receive treatment with cyclosporine only after appropriate treatment of such changes, unless alternative effective therapy exists. Experimental studies have not revealed the teratogenic effect of cyclosporine. Experience with the use of cyclosporine in pregnant women is limited. Data obtained from patients who have undergone organ transplantation indicate that, in comparison with traditional methods, treatment with cyclosporine does not have a negative effect on the course and outcome of pregnancy. Cyclosporine passes into breast milk. If it is necessary to prescribe cyclosporine during breastfeeding, breastfeeding should be discontinued.

Cyclosporine is a drug, an immunosuppressant that inhibits the function of the cellular component of immunity and prevents rejection of a transplanted organ or tissue.

General information about the study

Cyclosporine is a strong immunosuppressant used to prevent organ and tissue transplant rejection. It selectively affects T-lymphocytes and inhibits the cellular component of the immune system. In addition to transplantation, cyclosporine is used to treat autoimmune diseases: endogenous uveitis, rheumatoid arthritis, severe psoriasis and atopic dermatitis, glomerulonephritis, chronic, treatment-resistant urticaria. Unlike cytostatics, cyclosporine does not inhibit hematopoiesis and phagocytosis.

Pharmacokinetic parameters of absorption and half-life of the drug vary depending on the dosage form, individual characteristics of the patient, and drug interactions. In the liver, cyclosporine is actively transformed by the enzyme CYP3A4 to 30 less active metabolites. The drug is excreted primarily in bile and only in small amounts in urine.

Cyclosporine interacts with many drugs, increases the neuro- and nephrotoxicity of antibiotics and antifungals, and other immunosuppressants. It has a narrow therapeutic window with frequent development of adverse events, which indicates the need for regular monitoring of its concentration in the blood.

Most side effects of cyclosporine are dose dependent. While taking the drug, increased blood pressure, headache, muscle pain, paresthesia, tremor, convulsions, nausea, vomiting, diarrhea, excess hair growth, gum hyperplasia, impaired liver function, pancreatitis, increased cholesterol levels in the blood, changes in electrolyte levels may occur. , bacterial, fungal, parasitic and viral infections, renal dysfunction.

During initial therapy with cyclosporine (the first 2 months after transplantation), it is recommended to maintain the drug concentration in the blood within the range of 150-400 ng/ml.

The target concentration of the drug in the blood depends on the clinical protocol for patient management, type of transplant, risk of rejection, and concomitantly taken immunosuppressants. 2 months after transplantation, the target dose and blood level of the drug are usually reduced to 75-300 ng/ml. Most patients have an optimal response to cyclosporine at a blood concentration of 100-400 ng/ml.

The material for analysis is taken immediately before the planned dose is administered. Whole blood is taken for the study, since up to 80% of the drug penetrates into red blood cells. Blood taken at other times has higher values. The level of cyclosporine in the blood can also be analyzed 2 hours after administration of the drug (C2 monitoring), but in this case it is impossible to rely on the therapeutic concentration of this immunosuppressant.

What is the research used for?

• Monitoring the concentration of cyclosporine in the blood, especially when co-prescribing drugs with the properties of inducers or inhibitors of the CYP3A4 enzyme;
• selection and correction of the optimal dose for immunosuppression with minimal toxicity;
• identification of toxic levels of the drug;
• assessment of drug interactions;
• monitoring the regularity of taking the drug.

When is the study scheduled?

• Immediately after prescribing cyclosporine 2-3 times a week, then periodically (once every 1-2 months) after achieving a stable or maintenance dose;
• if there is a suspected violation of the dosage of the drug;
• when adjusting the dose or changing the prescription of other drugs taken simultaneously;
• when side effects occur.

What do the results mean?

The therapeutic range of cyclosporine concentrations is indicated by the attending physician according to the clinical situation (maintenance/induction therapy). Toxic concentration: values ​​above 400 ng/ml.

The results of the study are analyzed only taking into account the clinical picture of the disease, treatment regimen, and drug interactions.

What can influence the result?

• Drugs that reduce the concentration of cyclosporine: barbiturates, carbamazepine, phenytoin; nafcillin, sulfadimidine when administered; rifampicin; octreotide; probucol; orlistat; preparations containing St. John's wort; troglitazone;
• drugs that increase the concentration of cyclosporine: some macrolide antibiotics (mainly erythromycin and clarithromycin); ketoconazole, fluconazole, itraconazole; diltiazem, nicardipine, verapamil; metoclopramide; oral contraceptives; danazol; methylprednisolone (high doses); allopurinol; amiodarone; cholic acid and its derivatives.

Drug interactions Cyclosporine

When cyclosporine is co-administered with potassium supplements or potassium-sparing diuretics, the risk of developing hyperkalemia increases. With the simultaneous administration of cyclosporine and drugs such as aminoglycoside antibiotics, amphotericin B, ciprofloxacin, melphalan, colchicine, trimethoprim, the risk of developing nephrotoxicity increases. The risk of side effects from the kidneys also increases when prescribed simultaneously with NSAIDs. When cyclosporine is co-administered with lovastatin or colchicine, the risk of myalgia and muscle weakness increases. Various drugs may increase or decrease plasma concentrations of cyclosporine by inhibiting or inducing liver enzymes involved in its metabolism and elimination. Drugs that increase the concentration of cyclosporine in the blood plasma: ketoconazole, some macrolide antibiotics (including erythromycin and josamycin), doxycycline, oral contraceptives, propafenone, some calcium channel blockers (including verapamil, diltiazem, nicardipine). Drugs that cause a decrease in the concentration of cyclosporine in the blood plasma: barbiturates, carbamazepine, phenytoin, metamizole sodium, rifampicin, nafcillin, as well as sulfadimidine and trimethoprim when administered intravenously. If combined use cannot be avoided, careful monitoring of cyclosporine blood concentrations and appropriate dose adjustments are necessary. Cyclosporine reduces the clearance of prednisolone, and treatment with high doses of prednisolone may increase the concentration of cyclosporine in the blood.

Overdose of the drug Cyclosporine, symptoms and treatment

Available experience with cyclosporine overdose is limited. Impaired renal function may develop, which is probably reversible. If there are appropriate indications, symptomatic treatment is carried out. Removal of cyclosporine from the body can be achieved through nonspecific measures, including gastric lavage. It should be borne in mind that cyclosporine is practically not excreted from the body during hemodialysis and hemoperfusion using activated charcoal.
