Pharmacotherapeutic group: non-steroidal anti-inflammatory drug (NSAIDs).
ATX code: M01AE01
Pharmacological properties of
The mechanism of action of ibuprofen, a derivative of propionic acid from the group of non-steroidal anti-inflammatory drugs (NSAIDs), is due to inhibition of the synthesis of prostaglandins – pain mediators, inflammation and hyperthermia. Indirectly blocks cyclooxygenase 1 (COX-1) and cyclooxygenase 2 (COX-2), as a result of which it inhibits prostaglandin synthesis. In addition, ibuprofen reversibly inhibits platelet aggregation. It has analgesic, antipyretic and anti-inflammatory effects. The analgesic effect is most pronounced for pain of an inflammatory nature. The drug lasts up to 8 hours.
Absorption – high, rapidly and almost completely absorbed from the gastrointestinal tract (GIT) (connection with plasma proteins – 90%). After taking the drug on an empty stomach in adults, ibuprofen is detected in blood plasma after 15 minutes, the maximum concentration (Cmax) of ibuprofen in blood plasma is reached after 60 minutes. Taking the drug with food can increase the time to reach maximum concentration (TCmax) up to 1-2 hours. The half-life (T1 / 2) is 2 hours. Slowly penetrates into the joint cavity, lingers in the synovial fluid, creating higher concentrations in it than in blood plasma. After absorption, about 60% of the pharmacologically inactive R-form slowly transforms into the active S-form. It is metabolized in the liver. It is excreted by the kidneys (unchanged no more than 1%) and, to a lesser extent, with bile.
In limited studies, ibuprofen was found in breast milk at very low concentrations.

Side effects are predominantly dose dependent. The following adverse reactions were observed with short-term use of ibuprofen in doses not exceeding 1200 mg / day. In the treatment of chronic conditions and with prolonged use, other adverse reactions may occur. The frequency of adverse reactions was estimated based on the following criteria: very frequent ( 1/10), frequent (from 1/100 to <1/10), infrequent (from 1/1000 to <1/100), rare (from 1/10 000 to <1/1000), very rare (<1/10 000), the frequency is unknown (data on frequency estimation are not available). Violations of the blood and lymphatic system ÐÂ· Very rare: hematopoiesis (anemia, leukopenia, aplastic anemia, hemolytic anemia, thrombocytopenia, pancytopenia, agranulocytosis). The first symptoms of such disorders are fever, sore throat, superficial oral ulcers, flu-like symptoms, severe weakness, nosebleeds, and subcutaneous hemorrhages, bleeding, and bruising of unknown etiology.

Overdose In children, overdose symptoms may occur after taking a dose exceeding 400 mg / kg body weight. In adults, the dose-dependent effect of an overdose is less pronounced. T1 / 2 of the drug in case of an overdose is 1.5-3 hours. Symptoms: nausea, vomiting, pain in the epigastric region or, less commonly, diarrhea, tinnitus, headache and gastrointestinal bleeding. In more severe cases, manifestations of the central nervous system are observed: drowsiness, rarely – agitation, convulsions, disorientation, coma. In cases of severe poisoning, metabolic acidosis and an increase in prothrombin time, renal failure, damage to liver tissue, decreased blood pressure, respiratory depression and cyanosis can develop. In patients with bronchial asthma, an exacerbation of this disease is possible. Treatment: symptomatic, with mandatory airway management, ECG monitoring and basic vital signs up to the normalization of the patient’s condition. Oral administration of activated charcoal or gastric lavage for 1 hour after taking a potentially toxic dose of ibuprofen is recommended. If ibuprofen has already been absorbed, alkaline drink may be prescribed in order to excrete the acid derivative of ibuprofen by the kidneys, forced diuresis. Frequent or prolonged seizures should be stopped in / in the introduction of diazepam or lorazepam. With exacerbation of bronchial asthma, the use of bronchodilators is recommended.
