Pharmacology
Paracetamol has analgesic properties; it acts on the CNS to produce analgesia. It also has antipyretic properties; it inhibits the actions of endogenous pyrogen on the hypothalamic heat regulating centres thereby leading to dissipation of body heat.
Pharmacokinetics: Absorption of paracetamol is rapid and almost completely absorbed from the gastrointestinal tract. Peak plasma levels are achieved within 0.5 to 2 hours.
Metabolism/Excretion: Paracetamol is extensively metabolised and excreted in the urine primarily as inactive glucuronate and sulphate conjugates (94%). Approximately 4% is metabolised via cytochrome P-450 oxidase to a toxic metabolite, which is detoxified by preferential conjugation with hepatic glutathione and excreted in the urine as conjugates of cysteine and mercapturic acid. When paracetamol is used chronically or taken in large doses, glutathione stores are depleted and hepatic necrosis occurs; 2% to 4% is excreted unchanged.
Elimination half-life: 1 to 3 hours.
Protein binding: varies from 20% to 50% at toxic serum concentration.
Indications
Analgesic and antipyretic actions. It is indicated for the treatment of mild to moderate pains, headache, toothache, earache, neuralgia and feverish conditions.
