This invention discloses a method for increasing the effectiveness of dextromethorphan (DM) as an antitussive agent (i.e., as a cough suppressant). This method involves the concurrent administration of DM and a second agent which inhibits the oxidative activity of debrisoquin hydroxylase, a cytochrome P450 oxidase enzyme. Effective anti-oxidant compounds include quinidine, yohimbine, and fluoxetine.
