Paracetamol Renewal effervescent tablets 500 mg 12 pcs. (Paracetamol)

Pharmacological action

Paracetamol (a derivative of paraaminophenol) has analgesic, antipyretic and mild anti-inflammatory effects. The exact mechanism of analgesic and antipyretic effects of paracetamol has not been established.

Apparently, it includes central and peripheral components.

The drug blocks cyclooxygenase I and II mainly in the central nervous system, affecting the centers of pain and thermoregulation. In inflamed tissues, cellular peroxidases neutralize the effect of paracetamol on cyclooxygenase, which explains the almost complete absence of an anti-inflammatory effect of

.

The drug does not adversely affect water-salt metabolism (sodium and water retention) and the gastrointestinal mucosa due to the lack of influence on the synthesis of prostaglandins in peripheral tissues.

From the digestive system: nausea, diarrhea, epigastric pain, increased activity of "liver" enzymes, usually without the development of jaundice, hepatonecrosis (dose-dependent effect).

Drug Interactions

Phenytoin reduces the effectiveness of paracetamol and increases the risk of hepatotoxicity.

Patients taking phenytoin should avoid frequent use of paracetamol, especially at high doses.

Probenecid almost halves the clearance of paracetamol, inhibiting the process of its conjugation with glucuronic acid.

With simultaneous administration, consideration should be given to reducing the dose of paracetamol.

Caution should be exercised while using paracetamol and inducers of microsomal liver enzymes (e.g. ethanol, barbiturates, isoniazid, rifampicin, carbamazepine, anticoagulants, zidovudine, amoxicillin + clavulanic acid, phenylbutazone, tricyclic antidepressants).

Overdose of

Symptoms: gastrointestinal upset (nausea, vomiting, decreased appetite, abdominal discomfort

and / or abdominal pain), pallor of the skin, sweating, malaise.

With simultaneous administration to adults of 7.5 g or more or children over 140 mg / kg, hepatocytes are cytolized with complete and irreversible liver necrosis, development of liver failure, metabolic acidosis and encephalopathy, which can lead to coma and death.

12–48 hours after administration of paracetamol, an increase in the activity of hepatic transaminases, lactate dehydrogenase, a concentration of bilirubin, and a decrease in the concentration of prothrombin are noted.

A detailed clinical picture of liver damage manifests itself in 1-2 days and reaches a maximum on 3-4 days.
