BIORPHEN is a generic formulation typically used for psychotropic indications, specifically a combination of phenothiazine derivatives. Its active pharmaceutical ingredient (API) is primarily chlorpromazine hydrochloride.
API Composition and Manufacturing Standards
Chlorpromazine hydrochloride, the API in BIORPHEN, conforms to pharmacopoeial standards such as USP, EP, or JP. It is synthesized through multi-step chemical processes involving phenothiazine core formation, chlorination, and hydrochloride salt conversion.
