Understanding MAREZINE and its Manufacturing Challenges

Chlorpromazine hydrochloride, marketed under diverse brand names, exemplifies a phenothiazine derivative whose synthesis involves multi-step chemical processes employing specialized raw materials. The API must adhere to strict pharmacopeial standards, such as those outlined by the USP, EP, or JP, encompassing purity, residual solvents, endotoxins, and contamination levels. Given these complexities, sourcing from trusted manufacturers with validated Good Manufacturing Practices (GMP) is essential to mitigate risks related to adulteration or variability.
