Introduction
Chlorpheniramine maleate is a widely used antihistamine primarily prescribed for allergy symptoms such as hay fever, conjunctivitis, and hives. Its efficacy and safety profile have made it a staple in both over-the-counter (OTC) and prescription markets globally. Ensuring a reliable supply chain for chlorpheniramine maleate is critical for pharmaceutical companies, healthcare providers, and regulatory agencies. This article offers an in-depth analysis of key suppliers, manufacturing sources, and global trends related to this essential API (Active Pharmaceutical Ingredient).
Overview of Chlorpheniramine Maleate
Chlorpheniramine maleate belongs to the alkylamine class of antihistamines. It functions by blocking H1 histamine receptors to reduce allergy symptoms. Historically developed in the mid-20th century, it remains one of the most commonly utilized antihistamines worldwide. Its widespread use necessitates a detailed understanding of the supply landscape, especially given recent geopolitical shifts, manufacturing consolidations, and regulatory considerations.
