Introduction
Exelon, the brand name for rivastigmine, is a cholinesterase inhibitor primarily prescribed for the treatment of mild to moderate Alzheimer's disease and Parkinson's disease dementia. As a vital therapeutic agent in neurology, the supply chain for Exelon involves a complex interplay of raw material sourcing, active pharmaceutical ingredient (API) manufacturing, formulation, and distribution channels. Understanding its key suppliers is crucial for stakeholders across the pharmaceutical landscape seeking supply stability, cost efficiency, and regulatory compliance.
Manufacturers of Active Pharmaceutical Ingredient (API)
The core component of Exelon is rivastigmine, a cholinesterase inhibitor synthesized via multiple chemical routes. The API manufacturing stage constitutes the most critical point in the supply chain, influencing drug quality, regulatory approval, and market availability.
