Pharmacodynamics and pharmacokinetics
Pharmacodynamics
Ketoconazole is a man-made imidazole . Has fungistatic and fungicidal effects. It inhibits the biosynthesis of ergosterol and disrupts the normal lipid composition of the cell wall of fungi.
It acts on Epidermophyton floccosum, dermatophytes of the genera Microsporum, Trichophyton, as well as fungi of the genus Pityrosporum and Candida.
Pharmacokinetics of the cream
When applied locally, the active substance is practically not subject to systemic absorption; with prolonged use, its content in the blood is not determined.
Pharmacokinetics of suppositories
Absorption into the systemic circulation when administered intravaginally is extremely low.
Pharmacokinetics of tablets
The bioavailability of ketoconazole reaches its greatest values when consumed with food. If this condition is met, the maximum content of the drug in the blood is achieved after 1-2 hours. Absorption of the active substance is reduced in persons with reduced acidity of gastric juice and achlorhydria .
Reaction with blood proteins reaches 99%. Widely distributed in organs and tissues, except for the cerebrospinal fluid. Metabolized in the liver with the release of a large number of inactive derivatives. The main routes of biotransformation are: aromatic hydroxylation, cleavage and oxidation of piperazine and imidazole rings, oxidative O-dealkylation. The half-life is approximately 10 hours.
It is excreted mainly in bile and feces.
Pharmacological properties of the drug Ketoconazole
Ketoconazole is a synthetic derivative of imidazoledioxolane. It has a fungicidal and fungistatic effect against dermatophytes, yeasts (genera Candida , Pityrosporum , Torulopsis , Cryptococcus ), dimorphic and higher fungi (eumycetes). Less sensitive to ketoconazole are Aspergillus spp ., Sporothrix schenckii , some Dermatiaceae , Mucor spp . and other fucomycetes, with the exception of Entomophthrales . Pharmacological properties are due to the ability to have a damaging effect on the cell membrane of fungi. By interacting with the enzyme 14-α demethylase, ketoconazole inhibits the biosynthesis of ergosterol, an essential membrane component, from lanosterol. Like other azole compounds, the mechanisms of antifungal action of ketoconazole include inhibition of cellular respiration processes, interaction with membrane phospholipids, disruption of the transformation of yeast fungi into filamentous forms, suppression of purine uptake, disruption of the biosynthesis of triglycerides and/or phospholipids. At high concentrations, ketoconazole can have a direct physicochemical effect on fungal membranes, exhibiting a fungicidal effect. Secondary resistance to ketoconazole does not develop. In the acidic environment of the stomach, it quickly dissolves to form hydrochloride, which is quickly absorbed. The bioavailability of ketoconazaole depends on the acid-producing function of the stomach. Coadministration with food may increase the absorption of ketoconazole. The maximum concentration in blood plasma is achieved 1–4 hours after oral administration. Widely distributed in most body fluids. Binding to blood plasma proteins is 84–99%, mainly with albumin. Elimination from blood plasma is biphasic. The half-life in the first phase is about 2 hours, in the terminal phase - about 8 hours. Partially metabolized by oxidation, dealkylation and aromatic hydroxylation. Most of ketoconazole and its metabolites are excreted in the bile and then excreted in the feces (57% within 4 days, of which 20–65% unchanged), the remainder is excreted in the urine (13% within 4 days, of which 2–4 % unchanged). When used externally, it is not subject to significant resorption. Systematic topical application in the form of 2% shampoo leads to the accumulation of ketoconazole in the hair keratin. When administered intravaginally, small amounts of ketoconazole enter the systemic circulation. The maximum plasma concentration in women after intravaginal use of 400 mg of ketoconazole ranges from 0–20.7 ng/ml.

Drug interactions Ketoconazole
The simultaneous use of drugs that reduce the acidity of gastric contents (anticholinergics and antacids, H2 receptor blockers) should be avoided. If such drugs are indicated, they should be taken no earlier than 2 hours after taking ketoconazole. With the simultaneous use of rifampicin and ketoconazole, the concentration of the latter in the blood decreases, and therefore these two drugs should not be taken simultaneously. Ketoconazole inhibits the activity of certain liver oxidases and may slow down the inactivation of drugs whose metabolism depends on the action of these enzymes. Increased levels of drugs prescribed in parallel with ketoconazole may increase the incidence of side effects. This applies to drugs such as cyclosporine, terfenadine, anticoagulants, methylprednisolone and probably busulfan. When co-administered with ketoconazole, the doses of these drugs should be reduced. Ketoconazole should not be co-administered with astemizole. After treatment with griseofulvin, it is recommended to take a break for 1 month and then begin treatment with ketoconazole.

Side effects of the drug Ketoconazole
When applied topically, a burning sensation and itching are possible, especially in the first days of treatment. When taken orally, in some cases, diarrhea, nausea, headache, dizziness, photophobia, paresthesia, thrombocytopenia, exanthema, itching may occur, and very rarely - alopecia, urticaria, rash and other manifestations of allergic reactions. When using ketoconazole in doses higher than recommended, reversible gynecomastia and oligospermia have been observed in rare cases. With a daily therapeutic dose of 200 mg (in 1 dose), a transient decrease in the level of testosterone in the blood plasma may develop; normalization of levels occurs less than 24 hours after taking ketoconazole. Patients with liver disease or hypersensitivity to ketoconazole very rarely develop hepatitis. In this case, ketoconazole is immediately discontinued. The risk of this complication increases in women over the age of 50 years, as well as after treatment with griseofulvin or hepatotoxic drugs. Sometimes there is a slight increase in the activity of transaminases or alkaline phosphatase, which does not require discontinuation of treatment with ketoconazole.

Use of the drug Ketoconazole
For candidiasis and pityriasis versicolor, the cream is applied to the skin at the affected area once a day; for seborrheic dermatitis - 1-2 times a day (depending on the severity of the disease). Treatment should be continued for several days after all symptoms of the disease disappear. Maintenance therapy for inflammation of the sebaceous glands is carried out 1–2 times a week. If no improvement in the patient's condition is observed during 4 weeks of therapy, ketoconazole cream should be discontinued. For adults with skin infections, it is prescribed orally at a dose of 200 mg/day once; if there is no effect, the daily dose should be increased to 400 mg once. Children weighing 15–30 kg are prescribed 100 mg 1 time per day; with a body weight of more than 30 kg - 200 mg/day in 1 dose. For vulvovaginal candidiasis, 1 tablet (200 mg) is prescribed intravaginally 2 times a day for 5 days. To prevent fungal infections in patients with immunodeficiency, the following is prescribed: adults - 400 mg of ketoconazole per day in 1 dose; children - 4–8 mg/kg per day. To ensure maximum absorption, ketoconazole should be taken orally with food. Treatment must be continued for at least 1 week after symptoms disappear or until negative results of mycological examination are obtained. The average duration of treatment for skin mycoses caused by dermatophytes is about 4 weeks; for pityriasis versicolor - 10 days; for candidiasis of the oral cavity and skin - 2-3 weeks; for onychomycosis - 6–12 months, depending on the rate of nail growth (the affected nail must grow completely); for systemic candidiasis - 1–2 months; for paracoccidioidomycosis, histoplasmosis, coccidioidomycosis - several months. Shampoo with warm water is applied to the scalp and left on the surface of the skin for 3-5 minutes, then rinsed off. For pityriasis versicolor, shampoo is used once a day, the course of treatment is 5 days. For seborrheic dermatitis and scalp lichen, use shampoo 2 times a week for 2–4 weeks. To prevent pityriasis versicolor, shampoo is used once a day for 3 days, seborrheic dermatitis and dandruff - once every 1-2 weeks. The average duration of treatment is 1–2 months. Use 1 suppository per day for 3–5 days, depending on the dynamics of the disease. If necessary, the course of treatment is repeated until complete clinical recovery, confirmed by laboratory tests.
Overdose
Overdose when using cream or suppositories
Since these forms of drug release do not reach the systemic bloodstream, signs of overdose are unlikely.
If cream or suppositories are swallowed, the stomach should be lavaged and symptomatic treatment should be started.
Overdose of pills
In case of an overdose of tablets, increased side effects are expected. Treatment of overdose: gastric lavage, symptomatic therapy.
Interaction
When used according to the instructions, Ketoconazole suppositories and cream (ointment) are almost not absorbed into the systemic circulation and interaction with other drugs is unlikely.
When Ketoconazole is used together with antacids (H2-histamine receptor blockers, aluminum hydroxide , proton pump inhibitors), the absorption of the former from the intestine is reduced. With these combinations, it is necessary to monitor the effectiveness of treatment with the drug and, if necessary, adjust its doses.
When Ketoconazole is used together with strong activators of the CYP3A4 isoenzyme ( Rifabutin , Isoniazid , Efavirenz , Rifampicin , phenytoin , Carbamazepine , Nevirapine ), a decrease in the bioavailability of the former is possible, which can result in a significant decrease in its effectiveness. If these combinations cannot be avoided, then it is necessary to monitor the effectiveness of the drug described and, if necessary, increase its dose.
When ketoconazole is used together with substances that suppress the CYP3A4 isoenzyme (antiviral and other drugs), the bioavailability of ketoconazole may increase. With these combinations, it is necessary to monitor the patient’s condition in order to identify signs of increased effect of Ketoconazole and, if necessary, reduce its dose.
When used simultaneously, Ketoconazole tablets can block CYP3A4-mediated drug transformation, as well as P-glycoprotein -mediated transport of substances. This leads to an increase in the concentrations of these drugs in the blood, which in turn causes an increase in their therapeutic or side effects.
Concomitant use of the following drugs with Ketoconazole is not recommended: Fentanyl , Tamsulosin , Rifabutin , Carbamazepine , rivaroxaban , Dasatinib , Trabectedin , Nilotinib , Salmeterol.
Ketoconazole tablets should be used with caution with the following drugs: buprenorphine , Alfentanil , Oxycodone , coumarins, Saxagliptin , Cilostazol , Digoxin , Repaglinide , Eletriptan , praziquantel , Ebastine , docetaxel , bortezomib , Imatinib , Busulfan , Ixabepilone , Erlotinib , Trimetrex at , Alprazolam , Lapatinib , vinca alkaloids, Buspirone , Aripiprazole , midazolam , Brotizolam , Haloperidol , Perospirone , Ramelterone , Quetiapine , Risperidone , indinavir , Maraviroc , Nadolol , Saquinavir , Aliskiren , Verapamil , Budesonide , Aprepitant , Cyclosporine , Ciclesonide , Dexamet azone , methylprednisolone , fluticasone , Tacrolimus , Sirolimus , Atorvastatin , Temsirolimus , Reboxetine , Imidafenacin , Fesoterodine , Solifenacin , Mozavaptan , Sildenafil , Tadalfil , Tolterodine , Cinacalcet , Alitretinoin , Tolvaptan .
KETOCONAZOLE DS
Interaction
Medicines that affect the metabolism of ketoconazole:
- inducers of microsomal oxidation, such as rifampicin, rifabutin, carbamazepine, isoniazid, nevirapine and phenytoin significantly reduce the bioavailability of ketoconazole. The use of ketoconazole with such drugs is not recommended;
- ritonavir increases the bioavailability of ketoconazole; therefore, when taken together, it is necessary to reduce the dose of ketoconazole.
The effect of ketoconazole on the metabolism of other drugs.
Ketoconazole may enhance or prolong the effect of drugs metabolized by cytochrome P 450, especially from the CYP3A group. The following should not be prescribed during a course of treatment with ketoconazole:
- terfenadine, astemizole, mizolastine, cisapride, dofetilide, quinidine, pimozide, bepridil, disopyramide, halofantrine, levacetylmethadol, domperidone and sertindole. The risk of severe ventricular tachycardia increases, incl. "pirouette" type;
- midazolam and triazolam (oral forms), HMG-CoA reductase inhibitors metabolized by the CYP3A4 isoenzyme, such as simvastatin and lovastatin, ergot alkaloids (dihydroergotamine, ergometrine, ergotamine, methylergometrine), nisoldipine, eplerenone, irinotecan, everolimus. The effects, including side effects, of these drugs are enhanced.
Drugs, when prescribed, it is necessary to monitor their concentration in the blood plasma, the severity of therapeutic effects and side effects
(their dose when taken together with ketoconazole should be reduced if necessary):
- indirect anticoagulants;
- HIV protease inhibitors, such as indinavir, saquinavir;
- some anticancer drugs, such as Vinca rosea
, busulfan, docetaxel, erlotinib, imatinib;
- blockers of “slow” calcium channels of the dihydropyridine series, metabolized by the CYP3A4 isoenzyme and, possibly, verapamil;
- some immunosuppressive drugs: cyclosporine, tacrolimus, sirolimus;
- sildenafil, tolterodine;
- some HMG-CoA reductase inhibitors, for example, atorvastatin;
- some glucocorticosteroids, such as budesonide, fluticasone, dexamethasone and methylprednisolone;
- other drugs: digoxin, carbamazepine, buspirone, alfentanil, alprazolam, brotizolam, rifabutin, trimetrexate, ebastine, reboxetine, quetiapine, solifenacin, cilostazol, eletriptan, fentanyl, repaglinide.
Ethanol and other hepatotoxic drugs increase the risk of developing damage to the liver parenchyma. When combined with ethanol, disulfiram-like reactions may occur.
Weakens the effect of amphotericin B.
Reduces the stimulating effect of corticotropin on the adrenal glands.
Increases the risk of breakthrough bleeding with simultaneous use of oral contraceptives with low hormone content.
Increases the toxicity of phenytoin.
Antacid and anticholinergic drugs, H2-histamine receptor blockers and other drugs that reduce gastric acidity reduce the absorption of ketoconazole.
special instructions
The cream is not intended for use in ophthalmic practice; it is also recommended to avoid contact with the eyes.
When using the cream immediately after long-term use of external glucocorticosteroids, skin irritation is possible, to relieve which it is recommended to continue treatment with local glucocorticosteroids in the morning and apply ketoconazole cream in the evening. Over the next 3 weeks, it is necessary to reduce the dose of the corticosteroid until it is completely discontinued.
For fungal infections of the scalp, it may be more preferable to use shampoo with Ketoconazole.
In very rare cases, when using suppositories, it is possible to develop a local allergy of the external genitalia in a partner.
To reduce the risk of relapse of the disease when using suppositories, it is recommended to simultaneously carry out therapy with a sexual partner.
The use of suppositories can reduce the reliability of barrier contraception.
The use of tablet forms of the drug is not advisable in the treatment of fungal meningitis , because ketoconazole does not pass through the blood-brain barrier poorly.
Due to the high risk of developing hepatotoxicity, the drug tablets should be used only in special cases when indicated and prescribed by a doctor.
Before starting tablet therapy, it is necessary to assess the level of liver function in order to exclude diseases, and during therapy it is necessary to regularly monitor blood counts, the condition of the kidneys, adrenal glands and liver, so as not to miss the appearance of signs of hepatotoxicity.
If glucocorticosteroids were used to treat skin diseases, then Ketoconazole tablets are prescribed only 14 days after their complete withdrawal.
Consuming acidic drinks increases the absorption of ketoconazole.
The drug Ketoconazole does not affect the ability to drive vehicles.
Special instructions for the use of the drug Ketoconazole
When using the cream immediately after long-term treatment with topical corticosteroids, skin irritation may occur. It is recommended to continue topical corticosteroid therapy in the morning and take ketoconazole in the evening. Then gradually reduce the dose of the steroid over 2–3 weeks until complete withdrawal. If you previously used a strong steroid drug, then it should be replaced with a drug with a weaker effect and the dose should be reduced according to the same scheme. Ketoconazole reduces the cortisol response to ACTH, so it is necessary to monitor adrenal function in patients with insufficiency of these glands, as well as in patients exposed to prolonged stress (complex surgery, intensive care). When taking ketoconazole for more than 2 weeks in a row, it is necessary to monitor liver function (before treatment, 2 weeks after the start of treatment and then monthly). When drinking alcohol during ketoconazole therapy, in exceptional cases, a disulfiram-like reaction to alcohol is observed, characterized by hyperemia, rash, peripheral edema, nausea and headache. The cream can be used during pregnancy and breastfeeding; oral administration is contraindicated.

Reviews about Ketoconazole
Reviews of ointments (creams) and suppositories with ketoconazole characterize them on the positive side. There are rare cases of side effects when using them. Reviews of shampoo with ketoconazole characterize it even better in the treatment of fungal infections of the scalp.
Tablets of the same name are prescribed extremely rarely due to their high ability to provoke side effects, so it is impossible to get a complete picture of the effectiveness of this form of release of the drug based on reviews.

If treatment of skin lesions was carried out with corticosteroids, then ketoconazole is prescribed no earlier than 2 weeks after their discontinuation.
In patients with achlorhydria or hypochlorhydria, ketoconazole may not be effective when taken orally due to an unpredictable decrease in absorption. Drinking acidic drinks increases the absorption of ketoconazole.
When used at a dose of 400 mg or more, there is a decrease in the cortisol response when stimulating the adrenal glands with ACTH, so during the treatment period it is necessary to monitor adrenal function in patients with adrenal insufficiency, as well as in patients exposed to significant stress (including extensive surgical interventions) .
