Indications & Uses
Dextromethorphan is indicated for:
Pharmacology
Dextromethorphan Hydrobromide is a cough suppressant that acts centrally on the cough centre in the medulla. Although it is structurally related to morphine, it has no analgesic properties and generally shows little sedative activity. No addiction has been observed even after fairly large doses are given over a prolonged period. It is absorbed quickly from the GI tract, taking effect within 15 to 30 minutes of oral administration, and its action lasts about 3 to 6 hours in conventional dosage form. The drug is extensively metabolised in the liver and is excreted in the urine both unchanged and as demethylated metabolites, including Dextrophan, which itself has some cough-suppressant activity. Together, the parent drug and its metabolites account for up to 50% of the ingested dose excreted in the urine over 24 hours, with about 8% excreted unchanged within the first 6 hours.
