pharmachologic effect

NSAIDs, a derivative of enolic acid, have anti-inflammatory, analgesic and antipyretic effects.

The mechanism of the anti-inflammatory effect of meloxicam is its ability to inhibit the synthesis of prostaglandins, known mediators of inflammation.

Meloxicam in vivo inhibits the synthesis of prostaglandins at the site of inflammation to a greater extent than in the gastric mucosa or kidneys. These differences are associated with more selective inhibition of COX-2 compared to COX-1. Inhibition of COX-2 is thought to mediate the therapeutic effects of NSAIDs, whereas inhibition of the constitutively present isoenzyme COX-1 may be responsible for gastric and renal side effects. The selectivity of meloxicam for COX-2 has been confirmed in various test systems, both in vitro and in vivo. The selective ability of meloxicam to inhibit COX-2 was demonstrated when using human whole blood as a test system in vitro. It was found that meloxicam (in doses of 7.5 mg and 15 mg) more actively inhibited COX-2, having a greater inhibitory effect on the production of prostaglandin E2 stimulated by lipopolysaccharide (reaction controlled by COX-2) than on the production of thromboxane, which is involved in the blood coagulation process ( reaction controlled by COX-1). These effects were dose dependent.

Ex vivo studies have shown that meloxicam (at doses of 7.5 mg and 15 mg) has no effect on platelet aggregation and bleeding time.

In clinical studies, gastrointestinal side effects generally occurred less frequently with meloxicam 7.5 and 15 mg doses than with other comparable NSAIDs. This difference in the frequency of side effects from the gastrointestinal tract is mainly due to the fact that when taking meloxicam, such phenomena as dyspepsia, vomiting, nausea, and abdominal pain were observed less frequently. The incidence of upper gastrointestinal perforation, ulceration, and bleeding associated with meloxicam use was low and dose-related.

Drug interactions

Other inhibitors of prostaglandin synthesis, including glucocorticoids and salicylates - concomitant use with meloxicam increases the risk of ulceration in the gastrointestinal tract and gastrointestinal bleeding (due to synergistic action). Concomitant use with other NSAIDs is not recommended.

Anticoagulants for oral administration, heparin for systemic use, thrombolytic agents - simultaneous use with meloxicam increases the risk of bleeding. In case of simultaneous use, careful monitoring of the blood coagulation system is necessary.

Antiplatelet drugs, serotonin reuptake inhibitors - simultaneous use with meloxicam increases the risk of bleeding due to inhibition of platelet function. In case of simultaneous use, careful monitoring of the blood coagulation system is necessary.

Lithium preparations - NSAIDs increase plasma lithium levels by reducing its excretion by the kidneys. The simultaneous use of meloxicam with lithium preparations is not recommended. If simultaneous use is necessary, careful monitoring of plasma lithium concentrations is recommended throughout the course of lithium use.

Methotrexate - NSAIDs reduce the secretion of methotrexate by the kidneys, thereby increasing its plasma concentration. The simultaneous use of meloxicam and methotrexate (at a dose of more than 15 mg per week) is not recommended. In case of simultaneous use, careful monitoring of renal function and blood count is necessary. Meloxicam may increase the hematological toxicity of methotrexate, especially in patients with impaired renal function.

Diuretics - the use of NSAIDs while taking diuretics in case of dehydration of patients is accompanied by a risk of developing acute renal failure.

Antihypertensive drugs (beta-blockers, ACE inhibitors, vasodilators, diuretics). NSAIDs reduce the effect of antihypertensive drugs due to inhibition of prostaglandins, which have vasodilating properties.

Angiotensin II receptor antagonists, as well as ACE inhibitors, when used together with NSAIDs, increase the decrease in glomerular filtration, which can thereby lead to the development of acute renal failure, especially in patients with impaired renal function.

Cholestyramine, by binding meloxicam in the gastrointestinal tract, leads to its faster elimination.

Pemetrexed - with the simultaneous use of meloxicam and pemetrexed in patients with CC from 45 to 79 ml/min, the use of meloxicam should be discontinued 5 days before starting pemetrexed and can be resumed 2 days after the end of treatment. If there is a need for concomitant use of meloxicam and pemetrexed, patients should be carefully monitored, especially for myelosuppression and the occurrence of gastrointestinal side effects. In patients with creatinine clearance <45 ml/min, the use of meloxicam with pemetrexed is not recommended.

NSAIDs, by acting on renal prostaglandins, may enhance the nephrotoxicity of cyclosporine.

When co-administering medicinal products with meloxicam that have a known ability to inhibit CYP2C9 and/or CYP3A4 (or are metabolized by these enzymes), such as sulfonylurea derivatives or probenecid, the possibility of pharmacokinetic interaction should be taken into account.

When used concomitantly with oral hypoglycemic agents (eg, sulfonylureas, nateglinide), a CYP2C9-mediated interaction is possible, which may lead to increased blood concentrations of both the hypoglycemic agents and meloxicam. Patients taking meloxicam concomitantly with a sulfonylurea or nateglinide should carefully monitor blood glucose concentrations due to the potential for hypoglycemia.

Dosage regimen

They are installed individually, depending on the intensity of pain and the severity of the inflammatory process. Prescribed IM at a dose of 7.5 mg or 15 mg 1 time/day.

As with other NSAIDs, the possibility of interstitial nephritis, glomerulonephritis, renal medullary necrosis, and nephrotic syndrome cannot be excluded.

special instructions

Patients with gastrointestinal diseases require regular monitoring. If ulcerative lesions of the gastrointestinal tract or gastrointestinal bleeding occur, meloxicams should be discontinued.

Gastrointestinal ulcers, perforation, or bleeding may occur at any time during the use of NSAIDs, with or without warning symptoms or a history of serious gastrointestinal complications. The consequences of these complications are generally more serious for older people.

When using meloxicam, serious skin reactions such as exfoliative dermatitis, Stevens-Johnson syndrome, and toxic epidermal necrolysis may develop. Therefore, special attention should be paid to patients who report the development of adverse events from the skin and mucous membranes, as well as hypersensitivity reactions to the drug, especially if such reactions were observed during previous courses of treatment. The development of such reactions is observed, as a rule, during the first month of treatment. If the first signs of skin rash, changes in mucous membranes or other signs of hypersensitivity appear, discontinuation of meloxicam should be considered.

Cases have been described when taking NSAIDs to increase the risk of developing serious cardiovascular thrombosis, myocardial infarction, angina, possibly fatal. This risk increases with long-term use of the drug, as well as in patients with a history of the above diseases and predisposed to such diseases.

NSAIDs inhibit the synthesis of prostaglandins in the kidneys, which are involved in maintaining renal perfusion. The use of NSAIDs in patients with reduced renal blood flow or reduced volume may lead to decompensation of latent renal failure. After discontinuation of NSAIDs, renal function usually returns to baseline levels. Those most at risk for developing this reaction are elderly patients, patients with dehydration, congestive heart failure, liver cirrhosis, nephrotic syndrome or acute renal impairment, patients concomitantly taking diuretics, ACE inhibitors, angiotensin II receptor antagonists, and also patients who have undergone major surgical interventions that lead to hypovolemia. In such patients, diuresis and renal function should be carefully monitored when initiating therapy.

The use of NSAIDs in combination with diuretics can lead to sodium, potassium and water retention, as well as a decrease in the natriuretic effect of diuretics. As a result, predisposed patients may experience increased signs of heart failure or hypertension. Therefore, careful monitoring of the condition of such patients is necessary, as well as maintaining adequate hydration.

Before starting treatment, a kidney function test is necessary. In case of combination therapy, renal function should also be monitored.

When using meloxicam (as well as most other NSAIDs), episodic increases in serum transaminase activity or other indicators of liver function are possible. In most cases, this increase was small and transitory. If the detected changes are significant or do not decrease over time, meloxicam should be discontinued and laboratory changes observed should be monitored.

Weakened or malnourished patients may be less able to tolerate adverse events and should be monitored closely.

Like other NSAIDs, meloxicam may mask the symptoms of an underlying infectious disease.

As a COX/prostaglandin synthesis inhibitor, meloxicam may have an effect on fertility and is therefore not recommended for women who have difficulty conceiving. In women undergoing examination for this reason, discontinuation of meloxicam is recommended.

In patients with mild to moderate renal insufficiency (creatinine clearance>25 ml/min), no dose adjustment is required.

In patients with liver cirrhosis (compensated), no dose adjustment is required.

Impact on the ability to drive vehicles using machinery

When driving or operating machinery, the possibility of dizziness, drowsiness, visual impairment or other central nervous system disorders should be taken into account. During the treatment period, patients must be careful when driving vehicles and engaging in other potentially hazardous activities that require increased concentration and speed of psychomotor reactions.
