Bulk Active Pharmaceutical Ingredient (API) Sources for DEMULEN 1/35-28

Last updated: August 11, 2025

Introduction

The pharmaceutical landscape relies heavily on the sourcing of Active Pharmaceutical Ingredients (APIs), which constitute the core therapeutic component of formulated drugs. For products like DEMULEN 1/35-28, a medication used to alleviate coughs and colds, ensuring a reliable supply of high-quality APIs is foundational for manufacturing, regulatory compliance, and market continuity. This report offers a comprehensive analysis of potential bulk API sources tailored for DEMULEN 1/35-28, considering quality standards, geographic considerations, regulatory frameworks, and market dynamics.

Understanding DEMULEN 1/35-28 and API Composition

DEMULEN 1/35-28 is presumed to be a proprietary formulation. Based on typical cough syrups, its core APIs likely include Dextromethorphan Hydrobromide and Guaifenesin, both common in OTC cough and cold medications. These APIs serve antitussive and expectorant functions, respectively. Accurate identification of API specifications is crucial for sourcing, especially considering the stringent quality, purity, and stability requirements dictated by regulatory authorities such as the FDA, EMA, and other international agencies.

Market Overview of API Suppliers

1. Global API Manufacturing Hubs

Key regions dominate the API supply chain, offering varied options in terms of quality, cost, and regulatory compliance:

• India:
  India remains the world's largest API producer, boasting numerous WHO-GMP and ISO-certified manufacturers. Companies such as Granules India, Sun Pharma, and Aarti Industries have extensive experience in synthesizing APIs like Dextromethorphan and Guaifenesin (see [1]).

• China:
  China supplies a significant portion of the global API market, with large-scale facilities operated by firms like Hubei Biocause Pharmacy and Shandong Xinhua Pharmaceutical. Although competitive on cost, regulatory hurdles and quality assurance remain areas for diligence ([2]).

• Europe and North America:
  These regions prioritize high-quality, GMP-compliant API production, often for markets with stringent regulatory requirements. Companies such as Candor Group and Vasudha Pharma manufacture APIs with advanced quality systems tailored for international markets ([3]).

2. API Sources Specific to Dextromethorphan Hydrobromide

• Major Suppliers:

  • Glenn Pharma (India)
  • Hubei Xinzheng Pharmaceutical (China)
  • Vasudha Pharma Chem Ltd. (India)

• Quality Standards:
  Suppliers certify their APIs per pharmacopeial standards such as USP, EP, or BP, ensuring API purity (> 99%), low residual solvents, and proper Particle Size Distribution.

3. API Sources Specific to Guaifenesin

• Major Suppliers:

  • Jubilant Life Sciences (India)
  • Shandong Sino-Pharm Chem (China)
  • Pranav Antioxidants & Chemicals (India)
