Naltrexone Base API: Injectable & Micronized Grades for Long-Acting Formulations

Naltrexone Base is a potent, long-acting opioid antagonist with high affinity for μ-opioid receptors. By competitively blocking these receptors, it neutralizes the effects of exogenous opioids and reduces the cravings associated with alcohol dependence. It is the preferred active ingredient for Extended-Release (ER) injectables and implants, providing therapeutic coverage for up to 30 days.

At Micro Orgo Chem (MOC), we manufacture Naltrexone Base in our GMP certified facility. We understand that for long-acting suspensions, particle size is paramount. We offer Micronized Grades with precision-controlled Particle Size Distribution (PSD) and a validated Injectable Grade processed under strict aseptic conditions to ensure non-pyrogenicity and high stability.

Our API is compliant with USP, EP (Ph. Eur.), and IP pharmacopeias, supporting global partners in the critical field of addiction recovery medicine.
