Yes, Corex is banned in india. According to rule,fixed dose combination of centrally acting, antitussive with antihistamine, having high atropine like activity in expectorants is banned. Corex contains chlorpheniramine
maleate which is an antihistaminic having atropine like activity, and codeine which is a centrally acting antitussive. Each 5 ml of Corex Cough Syrup contains alcohol IP 8mg,chlorpheniramine Maleate IP 4 mg,Codeine Phosphate IP 10 mg,Carmoisine and Sunset.Corex cough syrup is indicated for the treatment of dry, irritating, disturbing cough in allergic or infective conditions of the respiratory passage, e.g., sinusitis, high fever
, acute bronchitis, tuberculosis
, and tropical eosinophilia
.Corex also if taken on a long term basis may lead to addiction due to presence of alcohol and codeine. In elderly persons, it may lead to respiratory depression. It is still available in large parts of India. According to me, it is not preferable to have a banned drug.Even you take it, you should not purchase it without prescription of physician. Hope, I satisfied your queries.
