Nonsteroidal anti-inflammatory and antirheumatic drugs. ATC code M01A X17.
Pharmacological properties
Pharmacodynamics.
Nimesulide is a nonsteroidal anti-inflammatory drug (NSAID) of the methanesulfonanilide group, which exhibits anti-inflammatory, analgesic and antipyretic effects. The therapeutic effect of nimesulide is due to the fact that it interacts with the arachidonic acid cascade and reduces prostaglandin biosynthesis by inhibiting cyclooxygenase.
Pharmacokinetics.
In humans, nimesulide is well absorbed after oral administration, reaching a maximum concentration in blood plasma after 2-3 hours. Up to 97.5% of nimesulide binds to blood plasma proteins. Nimesulide is actively metabolized in the liver with the participation of CYP2C9, an isoenzyme of cytochrome P450. The main metabolite is a parahydroxy derivative, which also has pharmacological activity. The half-life is from 3.2 to 6 hours. Nimesulide is excreted from the body with urine - about 50% of the dose taken. About 29% of the dose taken is excreted with feces in a metabolized form. Only 1-3% is excreted from the body unchanged. The pharmacokinetic profile in the elderly does not change.
Indication
Treatment of acute pain, primary dysmenorrhea.
Nimesulide should only be used as a second-line drug.
The decision to prescribe nimesulide should be made based on an assessment of all risks for the individual patient.
Contraindication
Hypersensitivity to nimesulide or to any component of the drug.
History of hyperergic reactions (bronchospasm, rhinitis, urticaria) to the use of acetylsalicylic acid or other NSAIDs.
History of hepatotoxic reactions to nimesulide.
Concomitant use of other substances with potential hepatotoxicity.
Alcoholism and drug addiction.
History of gastrointestinal bleeding or perforation associated with previous use of NSAIDs.
Gastric or duodenal ulcer in the acute phase, history of ulcer, perforation or bleeding in the digestive tract.
History of cerebrovascular bleeding or other hemorrhages, as well as diseases accompanied by bleeding.
Severe blood clotting disorders.
Severe heart failure.
Severe renal impairment.
Liver dysfunction.
Patients with fever and/or flu-like symptoms.
Children under 12 years old.
Third trimester of pregnancy and breastfeeding period.
Interaction with other medicinal products and other types of interactions
Pharmacodynamic interactions.
Corticosteroids: Increased risk of gastrointestinal ulceration or bleeding.
Antiplatelet agents and selective serotonin reuptake inhibitors (SSRIs): increased risk of gastrointestinal bleeding.
Anticoagulants: NSAIDs may enhance the effect of anticoagulants such as warfarin or acetylsalicylic acid, which is why this combination is contraindicated in patients with severe coagulation disorders. If such combination therapy cannot be avoided, careful monitoring of blood coagulation parameters is necessary.
In healthy volunteers, nimesulide rapidly reduces the sodium-excreting and, to a lesser extent, potassium-excreting effects of furosemide, and also reduces the diuretic effect. Simultaneous administration of nimesulide and furosemide leads to a decrease (approximately 20%) in the area under the concentration-time curve (AUC) and a decrease in the cumulative excretion of furosemide without changes in the renal clearance of furosemide.
Pharmacokinetic interactions with other drugs.
There have been reports that NSAIDs reduce lithium clearance, leading to increased plasma lithium levels and lithium toxicity. When prescribing Nimesulide to patients receiving lithium therapy, frequent monitoring of plasma lithium levels should be performed.
There is no clinically significant interaction with glibenclamide, theophylline, warfarin, digoxin, cimetidine and antacids (aluminum and magnesium hydroxide combination) in vivo. Nimesulide inhibits the activity of the CYP2C9 enzyme. When drugs that are substrates of this enzyme are used simultaneously with Nimesulide, their plasma concentrations may increase. Caution is required if nimesulide is administered less than 24 hours before or less than 24 hours after taking methotrexate, since it is possible to increase the level of the latter in the blood serum and increase its toxicity.
Due to their effect on renal prostaglandins, synthetase inhibitors, to which nimesulide belongs, may increase the nephrotoxicity of cyclosporines.
The effect of other drugs on nimesulide.
In vitro studies have shown that nimesulide is displaced from its binding sites by tolbutamide, salicylic acid and valproic acid. Although these interactions have been identified in plasma, these effects have not been observed during clinical use of the drug.
Application features
Undesirable side effects can be minimized by using the lowest effective dose for the shortest period of time necessary to control symptoms.
If the treatment is ineffective (reduction in symptoms of the disease), therapy with the drug should be discontinued.
During treatment with nimesulide, it is recommended to avoid the simultaneous use of hepatotoxic drugs, as well as to refrain from drinking alcohol. The use of nonsteroidal anti-inflammatory drugs may mask an increase in body temperature associated with a background bacterial infection. In the event of an increase in body temperature or the appearance of flu-like symptoms in patients using nimesulide, the drug should be discontinued.
Serious hepatic reactions, including fatalities, have been reported during treatment with nimesulide. Patients who develop symptoms suggestive of liver disease, such as anorexia, nausea, vomiting, abdominal pain, fatigue, dark urine, or patients with abnormal liver function tests should discontinue the drug. Re-administration of nimesulide to such patients is contraindicated. During treatment with nimesulide, the patient should refrain from taking other analgesics. Concomitant use of other NSAIDs, including selective cyclooxygenase-2 inhibitors, should be avoided.
Patients taking nimesulide who develop flu-like symptoms should discontinue its use.
Elderly patients have an increased frequency of adverse reactions to NSAIDs, especially possible bleeding and perforations in the digestive tract, which can be fatal.
Ulceration, bleeding or perforation in the digestive tract can be life-threatening, especially if there is a history of similar events in the patient when using any other NSAIDs (without a prescription). The risk of such events increases with increasing NSAID dose in patients with a history of gastrointestinal ulcer, especially complicated by bleeding or perforation, and in elderly patients. In such patients, treatment should be started with the lowest possible effective dose. For these patients, as well as for those taking concomitant low doses of acetylsalicylic acid or other drugs that increase the risk of gastrointestinal complications, the possibility of using combination therapy with protective agents, such as misoprostol or proton pump inhibitors, should be considered.
Patients with toxic lesions of the digestive tract, especially elderly patients, should report any unusual symptoms that occur in the digestive tract, especially bleeding. This is especially important in the initial stages of treatment. Patients taking concomitant medications that may increase the risk of ulceration or bleeding, such as corticosteroids, anticoagulants, selective serotonin reuptake inhibitors, antiplatelet agents (acetylsalicylic acid), should be informed of the need to exercise caution when using nimesulide.
If a patient receiving Nimesulide experiences bleeding or ulcers in the digestive tract, treatment with the drug should be discontinued.
Concomitant use of nimesulide with other drugs, such as oral contraceptives, anticoagulants, antiplatelet agents, may cause exacerbation of Crohn's disease and other diseases of the digestive tract.
Patients with a history of hypertension and/or heart failure, as well as patients with fluid retention and edema due to the use of NSAIDs, require appropriate monitoring of their condition and consultation with a doctor.
Clinical trials and epidemiological data suggest that some NSAIDs, especially at high doses and with long-term use, may carry a small risk of arterial thrombotic events, such as myocardial infarction and stroke. There is insufficient data to exclude a risk of such events with nimesulide.
Patients with uncontrolled hypertension, acute heart failure, established ischemic heart disease, peripheral arterial disease and/or cerebrovascular disease should be prescribed nimesulide after careful assessment of the condition. The same should be done before prescribing the drug to patients with risk factors for cardiovascular disease, such as hypertension, hyperlipidemia, diabetes mellitus, and smoking.
Patients with impaired renal function or heart failure should be prescribed the drug with caution due to the possibility of worsening renal function. In case of deterioration of the patient's condition, treatment should be discontinued.
Elderly patients require careful monitoring due to the possibility of bleeding and perforation of the gastrointestinal tract, deterioration of renal, hepatic or cardiac function. Since nimesulide may affect platelet function, it should be prescribed with caution to patients with hemorrhagic diathesis. However, nimesulide does not replace acetylsalicylic acid in the prevention of cardiovascular diseases.
Skin reactions.
Cases of fixed drug eruption have been reported with nimesulide. Nimesulide should not be re-administered to patients with a history of fixed drug eruption associated with nimesulide (see section 4.8).
There have been rare reports of severe skin reactions with NSAIDs, some of which may be fatal, such as exfoliative dermatitis, Stevens-Johnson syndrome, toxic epidermal necrolysis. In most cases, if these reactions occurred during the first month of previously prescribed treatment, the risk of their occurrence in patients is significantly increased. Nimesulide should be discontinued at the first signs of skin rash, mucosal lesions and other allergic manifestations.
Use during pregnancy or breastfeeding
Inhibition of prostaglandin synthesis may adversely affect pregnancy and/or foetal development. Epidemiological data suggest that use of prostaglandin synthesis inhibitors in early pregnancy may increase the risk of spontaneous abortion, foetal heart defects and gastroschisis. The absolute risk of cardiovascular malformation has been reported to increase from less than 1% to approximately 1.5%. The risk is thought to increase with dose and duration of exposure.
Nimesulide should not be taken during the first and second trimesters of pregnancy unless clearly necessary. If the drug is used in women attempting to conceive or during the first and second trimesters of pregnancy, the lowest possible dose and the shortest possible duration of treatment should be used.
In the third trimester of pregnancy, all prostaglandin synthesis inhibitors can lead to the development of the following in the fetus:
pneumocardial toxic lesion (with premature closure of the ductus arteriosus and hypertension in the pulmonary artery system);
renal dysfunction, which may progress to renal failure with the development of oligohydramnios.
In the mother and fetus at the end of pregnancy, it is possible:
increased bleeding time, anti-aggregation effect, which can occur even when using very low doses of the drug;
suppression of uterine contractile activity, which can lead to a delay or prolongation of the period of labor.
Therefore, nimesulide is contraindicated in the third trimester of pregnancy.
As an NSAID that inhibits prostaglandin synthesis, nimesulide can cause premature closure of the ductus arteriosus, pulmonary hypertension, oliguria, oligohydramnios. The risk of bleeding, labor weakness and peripheral edema increases. There are isolated reports of renal failure in infants whose mothers used nimesulide at the end of pregnancy. The potential risk for humans has not been determined, therefore, the use of nimesulide in the I and II trimesters of pregnancy is not recommended.
Since it is not known whether nimesulide passes into breast milk, its use is contraindicated during breastfeeding.
Nimesulide may impair female fertility and is therefore not recommended for use in women attempting to conceive. Women who are unable to conceive or who are undergoing investigation of infertility should consider discontinuing nimesulide. If pregnancy occurs during treatment with nimesulide, the physician should be informed.
Ability to influence reaction speed when driving vehicles or other mechanisms
Studies of the effect of nimesulide on the ability to drive or use machines have not been conducted, but if patients experience headache, dizziness, or drowsiness while taking nimesulide, they should refrain from driving or operating machinery.
Method of administration and doses
To minimize possible unwanted side effects, it is necessary to use the minimum effective dose for the shortest possible time. It is recommended to use after meals and drink plenty of fluids.
The maximum duration of treatment with Nimesulide is 15 days.
Adults: 1 tablet (100 mg) 2 times a day.
Elderly patients: No dose adjustment is required.
Children over 12 years of age: No dose adjustment is required.
Patients with renal impairment. For patients with mild or moderate renal impairment (creatinine clearance 30-80 ml/min), no dose adjustment is required, while severe renal impairment (creatinine clearance < 30 ml/h) is a contraindication to the use of Nimesulide.
Children.
Nimesulide is contraindicated in children under 12 years of age.
Overdose
Symptoms of acute overdose with NSAIDs are usually limited to the following: apathy, drowsiness, nausea, vomiting, epigastric pain. These symptoms are usually reversible with supportive therapy. Gastrointestinal bleeding, arterial hypertension, acute renal failure, respiratory depression, coma are possible, but such phenomena are rare. There have been reports of anaphylactoid reactions when using therapeutic doses of NSAIDs and in case of their overdose. There is no specific antidote. Treatment of overdose is symptomatic and supportive. There is no data on the removal of nimesulide by hemodialysis, but if we take into account the high degree of binding of nimesulide to blood plasma proteins (up to 97.5%), then dialysis is unlikely to be effective. In the presence of symptoms of overdose or after the use of a large dose of the drug within 4 hours after its administration, patients may be prescribed: artificial induction of vomiting, and/or administration of activated charcoal (60-100 g for adults) and/or administration of an osmotic laxative. Forced diuresis, increased urine alkalinity, hemodialysis and hemoperfusion may be ineffective due to the high degree of binding of nimesulide to blood plasma proteins. Kidney and liver function should be monitored.
