Understanding Paliperidone Palmitate: The API for INVEGA HAFYERA
Paliperidone palmitate is a long-acting injectable formulation of paliperidone, a serotonin-dopamine antagonist. As a produrg of paliperidone, it allows for sustained drug release, reducing dosing frequency and improving patient adherence. The API’s synthesis involves complex chemical processes, requiring advanced manufacturing capabilities and stringent quality controls to meet pharmacopeial standards (USP, EP, JP).

The supply chain for this API involves multiple stages: active ingredient synthesis, esterification to form palmitate, purification, and formulation. Ensuring consistent quality and supply is critical for maintaining the efficacy and safety profile of INVEGA HAFYERA.
