The manufacturing process of minocycline hydrochloride API is performed under proper quality control systems that comply with the regulations of international Good Manufacturing Practice (GMP) to provide safe and high-quality API.  

Minocycline undergoes a chemical reaction where the dimethyl amino group protonates, producing the salt form of minocycline, minocycline hydrochloride, from hydrochloric acid solutions. Impurities are then extracted from the active ingredient by crystallization, centrifugation, drying, filtration, milling, and/or sieving. Minocycline hydrochloride is thoroughly purified and tested in accordance with quality standards until it achieves 99% min purity.
