Pharmacology & Mechanism of Action
Dextromethorphan Hydrobromide is a cough suppressant which has a central action on the cough centre in the medulla. Although structurally related to morphine, it has no analgesic properties and in general it has little sedative activity. Addiction has not been observed after the administration of rather large doses for prolonged period. It is rapidly absorbed from the GI tract and exerts its effects in 15-30 minutes after oral administration. The duration of action is approximately 3-6 hours with conventional dosage form. Dextromethorphan hydrobromide is extensively metabolised in the liver and excreted in the urine as unchanged Dextromethorphan and demethylated metabolites including Dextrophan which has some cough suppressant activity. Urinary excretion of parent and metabolites accounts for up to 50% of the ingested dose over 24 hours. About 8% of the dose is excreted unchanged in the urine over the first 6 hours.
