If the overdose occurred within the last 4 hours, - induction of vomiting and / or administration of activated charcoal (from 60 to 100 g per adult) and / or osmotic laxative. Forced diuresis and hemodialysis are ineffective due to the high binding of the drug to proteins (up to 97.5%). Control of kidney and liver function is indicated.

Selective inhibitor of cyclooxygenase, an enzyme involved in the synthesis of PG. The functional group in nimesulide is sulfonylide. In research in vivo and in vitro it was found that nimesulide mainly inhibits cyclooxygenase II, the synthesis of which prevails in the process of inflammation, and has a minimal effect on cyclooxygenase I, which has a protective effect on the gastric or renal mucosa. In an inflammatory reaction, it affects neutrophils at the second stage of the cellular response. Effectively reduces the production of oxidants during the interaction of neutrophils with chemotaxis factors (direct cellular action), while not reducing the locomotor properties of the cell and does not limit the absorption efficiency of neutrophils during phagocytosis. It acts as an activator of hypochloric acid in the process of phagocytosis (recycling process). Prevents the formation of chloramine in neutrophils and toxic tissue damage by chlorinated oxidants in inflammatory processes

Nimesulide is an NSAID from the class of sulfonamides. It has anti-inflammatory, analgesic and antipyretic effects. Nimesulide acts as an inhibitor of the COX enzyme responsible for the synthesis of PG and mainly inhibits COX-2.

When taken orally, it is well absorbed. After a single dose of 100 mg C _max in plasma, it is noted after 2-3 hours and is 3-4 mg/l. AUC = 20-35 mg/l/h. There was no statistical difference between the above data and the values obtained when using the drug at a dose of 100 mg 2 times a day for 7 days. Up to 97.5% of the substance binds to plasma proteins.

It is metabolized in the liver. The main metabolite is the parahydroxy form, which has pharmacological activity. The estimated time before the appearance of the metabolite in the circulatory system is insignificant and is 0.8 hours, but the formation constant is small and significantly less than the absorption constant of nimesulide. Hydroxynimesulide is the only metabolite in the plasma and is almost completely free. T_1/2 it is from 3.2 to 6 hours. It is mainly excreted in the urine (approximately 50% of the administered dose). Only 1-3% is excreted unchanged. Hydroxynimesulide, the main metabolite, is found only in the form of glucuronide. Approximately 29% of the injected substance is released after biotransformation with feces.

The kinetic profile of nimesulide does not change in elderly patients with single and repeated administration.

With minor renal impairment (creatinine Cl 30-80 ml / min) C _max nimesulide and its metabolites do not exceed the level in healthy volunteers. Repeated use of the drug does not lead to accumulation. It is contraindicated in patients with impaired liver function due to the high risk of accumulation.

After oral administration, the drug is well absorbed from the gastrointestinal tract, reaching C_max in blood plasma after 2-3 hours, the bond with plasma proteins is 97.5%, T_1/2 it is 3.2-6 hours. It easily penetrates through histohematic barriers.

It is metabolized in the liver by the cytochrome P450CUR 2C9 isoenzyme. The main metabolite is the pharmacologically active parahydroxy derivative of nimesulide-hydroxynimesulide. Hydroxynimesulide is excreted in the bile in a metabolized form (found exclusively in the form of glucuronate-about 29%).

Nimesulide is excreted from the body, mainly by the kidneys (about 50% of the dose taken).

The pharmacokinetic profile of nimesulide in the elderly does not change with the administration of single and multiple/repeated doses.

According to an experimental study conducted with patients with mild to moderate renal insufficiency (creatinine Cl 30-80 ml / min) and healthy volunteers, C_max The concentration of nimesulide and its metabolite in the plasma of patients did not exceed the concentration of nimesulide in healthy volunteers. AUC and T_1/2 in patients with renal insufficiency, they were 50% higher, but within the values of pharmacokinetic parameters. With repeated administration of the drug, no accumulation is observed.

• Other non-narcotic analgesics, including non-steroidal and other anti-inflammatory drugs

• Non-steroidal anti-inflammatory drugs (NSAIDs) [Other non-narcotic analgesics, including non-steroidal and other anti-inflammatory drugs]

In the course of research in vivo there was no clinically significant interaction with glibenclamide, theophylline, warfarin, digoxin, cimetidine, and antacids. According to the results of the study, there was no clinically significant interaction. Aulin reduces the effectiveness of diuretics and, in particular, blocks the furosemide-stimulated increase in the concentration of renin in plasma. Pharmacokinetic analysis of the concentration of nimesulide in patients on continuous diuretic therapy (furosemide) revealed a clinically insignificant decrease in the volume of distribution. Enhances the effect of acetylsalicylic acid on hemostasis. Concomitant use of Aulin with salicylates or tolbutamide may affect the concentration of the latter in plasma and, consequently, their clinical effectiveness. NSAIDs reduce the clearance of lithium, which leads to an increase in plasma concentrations and the development of toxic effects (when prescribing nimesulide to patients undergoing therapy with lithium salts, it is necessary to regularly determine its concentration)

Pharmacodynamic interactions

GCS. Increase the risk of gastrointestinal ulcers or bleeding.

Antiplatelet agents and SSRIs, such as fluoxetine. Increase the risk of gastrointestinal bleeding.

Anticoagulants. NSAIDs may enhance the effects of anticoagulants such as warfarin. Due to the increased risk of bleeding, this combination is not recommended and is contraindicated in patients with severe coagulation disorders. If combination therapy still cannot be avoided, it is necessary to conduct careful monitoring of blood clotting indicators.

Diuretics. NSAIDs can reduce the effect of diuretics.

In healthy volunteers, nimesulide temporarily reduces the excretion of sodium under the action of furosemide, to a lesser extent-the excretion of potassium and reduces the actual diuretic effect.

Co-administration of nimesulide and furosemide leads to a decrease (approximately 20%) in AUC and a decrease in cumulative excretion of furosemide without changing the renal clearance of furosemide.

Concomitant administration of furosemide and nimesulide requires caution in patients with impaired renal or cardiac function.

ACE inhibitors and angiotensin-II receptor antagonists. NSAIDs can reduce the effect of antihypertensive drugs. In patients with mild to moderate renal insufficiency (creatinine Cl 30-80 ml / min) with the combined administration of ACE inhibitors, angiotensin II receptor antagonists or substances that suppress the COX system (NSAIDs, antiplatelet agents), further deterioration of renal function and the occurrence of acute renal failure, which is usually reversible. These interactions should be considered in patients taking Arslide^® in combination with ACE inhibitors or angiotensin II receptor antagonists. Therefore, co-administration of these drugs should be prescribed with caution, especially for elderly patients. Patients should receive adequate fluids, and renal function should be carefully monitored after starting co-therapy.

Pharmacokinetic interactions with other drugs

Lithium preparations. There is evidence that NSAIDs reduce the clearance of lithium, which leads to an increase in the concentration of lithium in the blood plasma and its toxicity. When prescribing nimesulide to patients receiving lithium therapy, regular monitoring of the plasma lithium concentration should be performed.

No clinically significant interactions with glibenclamide, theophylline, digoxin, cimetidine, or antacids (e.g., a combination of aluminum and magnesium hydroxides) were observed.

Nimesulide inhibits the activity of the CYP2C9 isoenzyme. When taking drugs that are substrates of this enzyme simultaneously with nimesulide, the concentration of these drugs in the plasma may increase.

When prescribing nimesulide less than 24 hours before or after taking methotrexate, caution is required, since in such cases, the level of methotrexate in the plasma and, accordingly, the toxic effects of this drug may increase.

Due to the effect on renal PG, COX inhibitors, such as nimesulide, can increase the nephrotoxicity of cyclosporins.

Interaction of other drugs with nimesulide

Researches in vitro It was shown that nimesulide is displaced from the binding sites by tolbutamide, salicylic acid and valproic acid, but these effects were not observed during clinical use of the drug.
