Ibuprofen, Paracetamol | Nurofen Intensive painkiller tablets 200 mg + 500 mg 6 pcs.

Pharmacological action

Combined drug whose action is due to its constituent components. It has a directed action against pain (analgesic), antipyretic and anti-inflammatory effect. Ibuprofen and paracetamol differ in the mechanism and place of action. As a result of their mutually reinforcing action, a more pronounced decrease in pain sensitivity and increased antipyretic effect are achieved than individually.

Ibuprofen, a derivative of propionic acid from the group of non-steroidal anti-inflammatory drugs (NSAIDs), has anti-inflammatory, decongestant, analgesic and antipyretic effects. The mechanism of action of ibuprofen is due to the inhibition of the synthesis of prostaglandins - mediators of pain, inflammation and hyperthermia, through the indiscriminate inhibition of the activity of cyclooxygenase 1 (COX-1) and cyclooxygenase 2 (COX-2). The analgesic effect of ibuprofen is provided by its inhibitory effect at the peripheral level. The antipyretic effect of ibuprofen is associated with a central inhibition of prostaglandin synthesis in the hypothalamus. Ibuprofen inhibits the migration of leukocytes into the focus of inflammation. In addition, ibuprofen reversibly inhibits platelet aggregation.

Paracetamol is an analgesic non-narcotic drug that has analgesic, antipyretic and mild anti-inflammatory effects. Indirectly blocks COX-2, primarily in the central nervous system. Paracetamol can also stimulate the activity of the descending pathways of serotonin, which leads to stopping the transmission of pain impulse in the spinal cord. At the peripheral level, paracetamol has a mild effect on COX-1 and COX-2.

The drug has a faster therapeutic effect and a more pronounced analgesic effect than ibuprofen and paracetamol separately. After taking one tablet of the drug, the analgesic effect is observed on average after 15 minutes, the clinically significant analgesic effect is achieved after 40 minutes and lasts for 8 hours. After taking two tablets of the drug, the analgesic effect is observed on average after 18 minutes, the clinically significant analgesic effect is achieved after 45 minutes and lasts for 9 hours.

Ibuprofen pharmacokinetics

: Absorption is high, rapidly and almost completely absorbed from the gastrointestinal tract (GIT). Communication with blood plasma proteins - 90%. Slowly penetrates into the joint cavity, lingers in the synovial fluid, creating higher concentrations in it than in blood plasma. It is found in blood plasma 5 minutes after taking the drug on an empty stomach, the maximum concentration (Cmax) in blood plasma is reached after 1-2 hours. Concomitant use with food can reduce the concentration of ibuprofen in blood plasma and increase the time to reach maximum concentration (Tmax). The degree of absorption of ibuprofen is independent of food intake. It is metabolized in the liver. After absorption, about 60% of the pharmacologically inactive R-form slowly transforms into the active S-form. The half-life (T1 / 2) is 2 hours. It is excreted by the kidneys mainly in the form of metabolites (unchanged no more than 1%) and, to a lesser extent, with bile in the form of metabolites. In the elderly, no significant differences were found in the pharmacokinetic profile of ibuprofen compared to younger people. There is evidence that ibuprofen was found in breast milk in low concentrations.

Paracetamol: absorption is high, quickly absorbed from the digestive tract. Communication with blood plasma proteins is insignificant when taken in therapeutic doses, slightly increased with an overdose. It is found in blood plasma 5 minutes after taking the drug on an empty stomach, Cmax in blood plasma is reached 30-40 minutes after administration. Concomitant use with food can reduce the concentration of paracetamol in blood plasma and increase Tmax. The degree of absorption of paracetamol is independent of food intake. It is metabolized in the liver and excreted mainly in the form of glucuronides and sulfated conjugates with the formation of glutathione conjugates (about 10%). It is excreted by the kidneys. In the form of unchanged paracetamol, less than 5% of the dose taken is excreted. The half-life (T1 / 2) is 3 hours. Hydroxylated metabolite N-acetyl-p-benzoquinoneimine, which is formed in small quantities in the liver and kidneys under the influence of mixed oxidases and is usually detoxified by binding to glutathione, can accumulate with an overdose of paracetamol and cause damage to liver tissue. The elderly did not show significant differences in the pharmacokinetic profile of paracetamol compared to younger people. The bioavailability and pharmacokinetic parameters of ibuprofen and paracetamol, taken as part of this combined preparation, do not change both with single and multiple use.

Infrequent: increased levels of aspartate aminotransferase, alkaline phosphatase, creatinine phosphokinase, decreased hemoglobin, increased platelet count.

If side effects occur, you should stop taking the drug and consult a doctor.

Overdose of

Paracetamol

Symptoms: symptoms of an overdose of paracetamol during the first 24 hours: pallor of the skin, nausea, vomiting, anorexia, and abdominal pain. Damage to the liver can occur 12-48 hours after administration, therefore it is necessary to consult a doctor even in the absence of symptoms. Possible impaired glucose metabolism and metabolic acidosis. In severe poisoning, liver failure can progress with complications such as encephalopathy, hemorrhage, hypoglycemia, cerebral edema, and death. Acute renal failure with acute tubular necrosis (defined by lower back pain, hematuria and proteinuria) can develop even in the absence of severe liver damage. There are reports of heart rhythm disturbances and pancreatitis.

Treatment: immediate treatment is needed in case of an overdose of paracetamol. Despite the failure of significant early symptoms, patients should be urgently taken to hospital for immediate medical examination. Symptoms may be limited to nausea or vomiting and may not match

severity of overdose or risk of organ damage. Activated carbon treatment should be considered if the excessive dose was taken less than 1 hour ago. Plasma paracetamol concentration should be measured 4 hours or more after administration (earlier concentrations are unreliable). Treatment with N-acetylcysteine ​​can be carried out up to 24 hours after taking paracetamol, however, the maximum protective effect is achieved after about 8 hours after taking the drug. The effectiveness of the antidote gradually decreases after this time. If necessary, N-acetylcysteine ​​is administered intravenously in accordance with the established regimen. Outside the hospital, if there is no vomiting, you can use methionine inside. Patients who have severe hepatic dysfunction 24 hours after taking the drug should be referred to a poisoning specialist.

Additional information on special patient groups

An increased risk of liver damage due to an overdose of paracetamol is most likely in:

· patients who are receiving long-term treatment with enzyme-inducing agents (such as carbamazepine, phenobarbitone, phenytoin, primidone, rifampicin and hypericum perforated) , alcohol users in amounts higher than recommended

· patients with glutathione depletion (eg patients with eating disorders, cystic fibrosis, HIV infection, cachexia, starving).

Ibuprofen

In adults, the dose-dependent effect does not have a clear threshold. The half-life of the drug with an overdose is 1.5-3 hours.

Symptoms: nausea, vomiting, epigastric pain or, less commonly, diarrhea, tinnitus, headache, and gastrointestinal bleeding. In more severe cases, manifestations from 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, lowering blood pressure, may develop respiratory depression and cyanosis. 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 within 1 hour after taking a potentially toxic dose of ibuprofen is recommended. If ibuprofen has already been absorbed, an alkaline drink may be prescribed to excrete the acid derivative of ibuprofen by the kidneys, forced diuresis. Frequent or prolonged seizures should be stopped by the intravenous administration of diazepam or lorazepam. If bronchial asthma worsens, the use of bronchodilators is recommended.
