How Has the Supply Chain Evolved and What Is Its Future?
Historical Trends
Initially produced by major pharmaceutical firms with branded formulations, manufacturing shifted predominantly to generics post patent expiry. The manufacturing process involves sterile compounding, which has faced regulatory crackdowns to limit unsafe preparations.
Current State and Future Outlook
- Consolidation of Suppliers: Reduced number of manufacturing entities due to regulatory compliance costs.
- Shift Toward Contract Manufacturing: Outsourcing to specialized sterile drug producers.
- Regulatory Trends: The FDA’s modernization efforts aim to tighten standards on compounded drugs (2021 Drug Quality Security Act updates).
