Overview of Promethegan and Its Active Ingredient: Prochlorperazine

Prochlorperazine is a first-generation antipsychotic agent classified under phenothiazines. Its widespread prescription for antiemetic and antipsychotic indications necessitates a reliable supply of high-quality active pharmaceutical ingredients (APIs). Promethegan, as a branded or generic form, utilizes prochlorperazine dihydrochloride as the core API. The manufacturing and distribution of this API are tightly regulated, with suppliers required to meet strict standards set by authorities such as the FDA (Food and Drug Administration), EMA (European Medicines Agency), and other global regulatory bodies.
