Pharmacological properties

Pharmacodynamics

GENITRON is a non-steroidal anti-inflammatory drug (NSAID), a COX inhibitor, has analgesic and antipyretic effects. The active substance - meloxicam, is a derivative of enolic acid, has a pronounced anti-inflammatory effect on all standard models of inflammation. The mechanism of its action is due to the ability to inhibit the synthesis of prostaglandins (inflammatory mediators) by selectively suppressing the enzymatic activity of COX-2. The selectivity of COX-2 inhibition decreases with the appointment of GenITRON in high doses and long-term use. In addition, it depends on the individual characteristics of the organism.

In vivo, meloxicam inhibits prostaglandin synthesis at the site of inflammation to a greater extent than in the gastric mucosa or kidneys. This is due to the selective inhibition of COX-2, which provides the therapeutic effect of NSAIDs. Its advantage is that inhibition of the persistent COX-1 isoenzyme is a common cause of gastric and renal adverse effects.

The selective ability of meloxicam to inhibit COX-2 has been confirmed by the results of in vitro and in vivo studies in various test systems.

It was found that at a dose of 7.5 mg or 15 mg meloxicam inhibited COX-2 more actively, exerting a predominant effect on the production of prostaglandin E2 than on the production of thromboxane, a reaction controlled by COX-1. In ex vivo studies, it was found that at a dose of 7.5 mg or 15 mg, meloxicam does not affect platelet aggregation and bleeding time.

Pharmacokinetics

After oral administration, absorption of meloxicam from the gastrointestinal tract occurs almost completely, its absolute bioavailability is 90%. The degree of absorption with the simultaneous intake of food and antacids does not change. The maximum concentration (C _max) of meloxicam in plasma is reached after 5-6 hours, it is dose-dependent. The equilibrium concentration (C _ss) in plasma occurs within 72–120 hours.

The bioavailability of meloxicam when administered intramuscularly is about 100%. After administration at a dose of 15 mg, its C _max in plasma is reached after about 1 hour.

Plasma protein binding (mainly albumin) - 99%.

Overcomes histohematogenous barriers. Its concentration in the synovial fluid reaches 50% of the plasma concentration.

The volume of distribution (V _d) after oral administration is approximately 16 liters, in / m administration - 11 liters.

Meloxicam is metabolized in the liver almost completely with the formation of four pharmacologically inactive metabolites. The conversion process occurs as a result of peroxidase oxidation and with the participation of isoenzymes CYP2C9 and CYP3A4.

The half-life (T _1/2) can range from 13 to 25 hours, with intramuscular administration - 20 hours. Plasma clearance after a single dose is 7-12 ml / min, intramuscular injection - 8 ml / min.

Up to 5% of the daily dose is excreted through the intestines unchanged, the rest - in the form of metabolites equally through the intestines and kidneys.

The pharmacokinetics of meloxicam in case of impaired liver function or mild to moderate renal failure does not change significantly. With renal failure of moderate severity, the rate of elimination of meloxicam from the body increases.

In patients with end-stage renal failure, the binding of the active substance to plasma proteins worsens, V _d increases, therefore it is recommended to use GenITRON in a daily dose not exceeding 7.5 mg.

Pharmacokinetic parameters in elderly patients do not change. They have slightly lower mean plasma clearance at steady state than younger patients.

In elderly women, the total concentration of meloxicam in the blood plasma and T _1/2 increase compared with patients of both sexes.

Treatment: there is no specific antidote, symptomatic therapy is prescribed. In case of an overdose of GenITRON in the form of tablets, immediate gastric lavage, intake of activated charcoal is indicated. The use of forced diuresis, urine alkalization or hemodialysis is ineffective.

special instructions

The development of severe side effects from the gastrointestinal tract can be prevented by using GenITRON in the minimum effective dose for a short course.

Patients with gastrointestinal pathologies require regular examinations. It should be borne in mind that at any stage of drug use, potentially fatal gastrointestinal bleeding, ulcers or perforation may occur, including in patients without a history of severe gastrointestinal diseases. If ulceration of the gastrointestinal tract or gastrointestinal bleeding is detected, the use of GenITRON should be discontinued. Particular care should be taken when treating elderly patients.

In case of cardiovascular diseases or in patients with risk factors for their development, the risk of serious cardiovascular thrombotic events, angina pectoris attack, myocardial infarction and stroke, including fatal ones, increases.

GENITRON can increase the retention of water, sodium, potassium and reduce the natriuretic effects of diuretics. In patients with heart failure or hypertension, patients should be tested for renal function before starting treatment, ensure that adequate hydration is maintained, and that clinical monitoring is performed.

Patients with dehydration, chronic heart failure, cirrhosis of the liver, nephrotic syndrome, chronic kidney disease who are on concomitant therapy with diuretics, angiotensin II receptor antagonists or angiotensin converting enzyme (ACE) inhibitors interventions), in old age. Therefore, in such patients it is necessary to monitor the urine output and the state of renal function before starting the use of GenITRON.

In case of a significant and persistent deviation from the norm in the indicators of transaminase activity or other indicators of liver function, treatment should be canceled, followed by control tests.

When using GenITRON, the ability of NSAIDs to mask the symptoms of infectious diseases should be taken into account.

When the first signs of hypersensitivity appear (skin rashes, mucosal lesions), immediate withdrawal of the drug is required.

Influence on the ability to drive vehicles and complex mechanisms

GenITRON can cause side reactions from the nervous system, therefore it is recommended to avoid potentially hazardous activities, including driving, during the period of drug use.

Application during pregnancy and lactation

The use of GenITRON during gestation and lactation is contraindicated.

Meloxicam is not recommended for women who are planning to conceive, it can affect fertility, cause a delay in ovulation.

Pediatric use

Age contraindications:

• tablets: up to 12 years old;
• solution for intramuscular injection: up to 18 years.

With impaired renal function

You can not use GenITRON in progressive kidney disease, for the treatment of patients with confirmed hyperkalemia, not undergoing hemodialysis, with severe renal failure (CC less than 30 ml / min).

Precautions should be taken in renal failure with CC 30-60 ml / min.

For violations of liver function

The appointment of GenITRON is contraindicated in patients with active liver disease or severe hepatic insufficiency.

No dose adjustment is required in compensated liver cirrhosis.

Use in the elderly

Care should be taken when prescribing NSAIDs in elderly patients.

Drug interactions

With the simultaneous use of GenITRON:

• salicylates, corticosteroids and other inhibitors of prostaglandin synthesis: there is a synergism of action and an increased risk of ulceration of the gastrointestinal tract mucosa (gastrointestinal tract) and gastrointestinal bleeding;
• anticoagulants, heparin for systemic use, thrombolytics: the likelihood of bleeding increases. If it is necessary to use this combination, it is necessary to monitor the indicators of the blood coagulation system;
• antiplatelet agents, serotonin reuptake inhibitors: inhibit platelet function, increase the risk of bleeding;
• lithium preparations: a significant decrease in renal excretion of lithium is possible, causing an increase in its concentration in the blood plasma until the toxicity level is reached, therefore, the combination of meloxicam with lithium preparations should be avoided;
• methotrexate: there is a decrease in renal excretion of methotrexate, which leads to an increase in its concentration in plasma. Therefore, if it is necessary to prescribe this combination, the weekly dose of methotrexate should not exceed 15 mg; careful monitoring of the functional state of the kidneys and blood counts is also required. The risk of increased hematological toxicity of methotrexate and other drugs that cause bone marrow suppression increases with impaired renal function, cytopenia may develop;
• intrauterine contraceptives: it is possible to reduce the contraceptive effect of intrauterine contraceptives;
• diuretics: increase the risk of acute renal failure;
• antihypertensive drugs: against the background of inhibition of prostaglandins, the therapeutic effect of ACE inhibitors, beta-blockers, vasodilators and diuretics decreases;
• angiotensin II receptor antagonists, ACE inhibitors: there is a synergism of action that reduces glomerular filtration. With impaired renal function, the risk of developing acute renal failure increases;
• cholestyramine: promotes faster elimination of meloxicam;
• cyclosporine: increased nephrotoxicity of cyclosporine;
• oral hypoglycemic agents: can enhance their therapeutic effect, increasing the risk of hypoglycemia;
• digoxin, cortisone, diuretics: may weaken their effect;
• drugs that can inhibit CYP2C9 and / or CYP3A4, or metabolized with the participation of these isoenzymes: may cause pharmacokinetic interactions with meloxicam;
• antacids, cimetidine, digoxin, furosemide: no pharmacokinetic interaction with these agents has been established.
