Introduction
Doxylamine succinate is a first-generation antihistamine primarily used as an over-the-counter sleep aid and for relief from allergy symptoms. Its sedative properties make it highly sought after in both over-the-counter (OTC) medications and prescription formulations. Recognizing the key suppliers for doxylamine succinate is crucial for pharmaceutical industry stakeholders, including manufacturers, distributors, and regulators, aiming for supply chain security, competitive procurement, and formulation development.
Global Manufacturing Landscape
The global landscape of doxylamine succinate supply is characterized by a limited number of large-scale API (Active Pharmaceutical Ingredient) producers primarily located in China, India, and a few European countries. These manufacturers serve as the backbone of the supply chain, providing raw material to pharmaceutical companies worldwide.
