Introduction
Bupropion hydrochloride and dextromethorphan hydrobromide are widely used pharmaceutical compounds with significant therapeutic applications. Bupropion is primarily prescribed for depression, smoking cessation, and ADHD, while dextromethorphan is a common cough suppressant found in many over-the-counter (OTC) and prescription formulations. The supply chain for these compounds is critical for pharmaceutical manufacturers, healthcare providers, and regulatory agencies. This article delineates key global and regional suppliers, exploring the landscape of manufacturing, sourcing, and distribution to inform stakeholders engaged in procurement, research, or regulatory operations.
