This drug was never marketed. Oxaprotiline is a racemic mixture of the isomers levoprotiline and dextroprotiline. Levoprotiline is the R or levo isomer of oxaprotiline (CGP-12,103-A). Dextroprotiline is the S or dextro isomer of oxaprotiline (CGP-12,104-A). Both enantiomers have antidepressant effects but levoprotiline also is an antihistamine and dextroprotiline has many other pharmacological actions."}]
