Overview of INDOCIN SR and Its API

INDOCIN SR, the sustained-release formulation of indomethacin, functions as an anti-inflammatory and analgesic agent primarily prescribed for arthritis, gout, and other inflammatory conditions. The active pharmaceutical ingredient (API), indomethacin, is a non-steroidal anti-inflammatory drug (NSAID) belonging to the acetic acid derivative class. The supply chain for indomethacin API is critical to ensuring drug quality, regulatory compliance, and cost-effectiveness. As of 2023, the global API market remains dynamic, influenced by manufacturing capacities, regulatory standards, geopolitical factors, and supply chain logistics.

Key Considerations in Selecting API Suppliers

Quality and Regulatory Compliance:
Suppliers must adhere to cGMP standards, with certifications from authorities such as the US Food and Drug Administration (FDA), European Medicines Agency (EMA), or World Health Organization (WHO). Certificates of Analysis (CoA), stability data, and regulatory dossiers are essential.

Manufacturing Capacity & Lead Time:
Capacity ensures uninterrupted supply, especially critical for sustained-release formulations. Lead times can vary from 3-6 months depending on the supplier’s batch size and regulatory clearance.

Cost and Contract Terms:
Pricing is influenced by manufacturing location, purity standards, and order volume. Long-term contracts can ensure price stability and priority manufacturing slots.

Supply Chain Reliability:
Diversification of sources reduces risks associated with geopolitical issues, raw material shortages, or regulatory disruptions.
