Introduction
Guaifenesin and pseudoephedrine hydrochloride are key active pharmaceutical ingredients (APIs) extensively used in over-the-counter (OTC) and prescription medications for respiratory ailments. Guaifenesin acts as an expectorant, facilitating mucus clearance, while pseudoephedrine hydrochloride is a potent decongestant commonly employed in cold and allergy remedies. The sourcing and supply chain management for these substances are critical, given their widespread utilization, regulatory scrutiny, and the complexities associated with their manufacturing and distribution.
This article provides a comprehensive overview of leading suppliers for both drugs, emphasizing their manufacturing capabilities, compliance standards, and strategic positioning in the global pharmaceutical supply chain. It aims to assist pharmaceutical industry stakeholders in identifying reliable sourcing options while considering regulatory and market dynamics.
