Abstract: A method of using inactive isomer compositions as drug-resistance-reversal agents and in prophylactic treatment includes the steps of selecting an antihistaminically-inactive isomer of a preselected antihistamine, and making stereoselective use of the antihistaminically-inactive isomer for a clinical purposes. The making step includes choosing one of the following clinical purposes for which to make stereoselective use of the antihistaminically-inactive isomer: treatment of malaria, prophylaxis of malaria; and treatment of drug-resistant malignancies. The step of selecting an antihistaminically-inactive isomer involves preselecting an antihistamine from the group consisting of chlorpheniramine (?), btompheniramine (?), fluorpheniramine (?), pheniramine (?), bromodiphenhydramine, doxylamine, prophenpyridamine, chlorcyclizine, dimethindene (+), carbinoxamine (+), chlorphenoxamine, clemastine, orphenadrine, hydroxyzine, meclizine, and buclizine.
