analgesic non-narcotic agent
Pharmacodynamics:Paracetamol has antipyretic and analgesic effect. The drug blocks cyclooxygenase 1 and 2 in CNS affecting the centers of pain and thermoregulation. In inflamed tissues, cellular pyroxidases neutralize the effect of paracetamol on cyclooxygenase, which explains the almost complete absence of anti-inflammatory effect of the drug. The absence of blocking effect on prostaglandin synthesis in peripheral tissues determines the absence of its negative effect on water-salt metabolism (Na+ and water retention) and erosive-ulcerative lesions of the gastrointestinal mucosa. Pharmacokinetics:
Paracetamol is rapidly and almost completely absorbed from the gastrointestinal tract. The maximum concentration of paracetamol in the blood is reached 16 – 28 hours after administration of the drug and is 26 – 56 mg/liter. When rectal administration the completeness of paracetamol absorption is lower than after oral administration.
Paracetamol is quickly and evenly distributed throughout the body tissues. With plasma proteins 10 – 15% of the taken dose is bound. Amount of distribution and bioavailability are not significantly different in children and adults. The drug penetrates through the blood-brain and placental barriers. Less than 1% of the administered dose goes into the breast milk of nursing mothers.
Paracetamol is metabolized by microsomal liver enzymes. About 80% forms conjugates with glucuronic acid and sulfates to 17% undergoes hydroxylation to form active metabolites that conjugate with glutathione. In overdose or lack of glutathione these metabolites can cause necrosis of hepatocytes.
The half-life of paracetamol is 20-40 hours. It may increase in patients with severe liver dysfunction and elderly patients. Twenty-four hours after taking it, 85-90% of paracetamol is excreted in the urine as glucoronides and sulphates; 3% of it remains unchanged.
In children under 10 – 12 years of age, the formation of conjugates with sulfates is the main route of metabolism and excretion of paracetamol. The likelihood of hepatotoxic effects in children is lower than in adults. Other pharmacokinetic parameters of adults and children do not differ.
