Abstract

See full text

This invention discloses a method for treating human patients suffering from dermatitis, particularly severe dermatitis which does not respond adequately to non-prescription drugs. Such patients are treated using dextromethorphan (DM), an antitussive agent normally used in cough syrup. If the patient is a so-called 'extensive metabolizer,' an antioxidant drug (such as quinidine) can be coadministered to inhibit the DM-degrading activity of debrisoquin hydroxylase, an enzyme that will rapidly convert DM into its metabolite, dextrorphan. This treatment has been shown to be highly effective in treating severe dermatitis, and in most patients this drug combination causes no significant adverse side effects.
