Bulk Active Pharmaceutical Ingredient (API) Sources for: STALEVO 75

Last updated: July 30, 2025


Introduction

STALEVO 75 combines entacapone, levodopa, and carbidopa into a single formulation for the management of Parkinson’s disease. At the core of this medication are three active pharmaceutical ingredients (APIs): entacapone, levodopa, and carbidopa. The sourcing of high-quality APIs is critical for pharmaceutical manufacturers aiming to ensure product safety, efficacy, and regulatory compliance. This article provides a comprehensive overview of bulk API sources for STALEVO 75, including key suppliers, quality considerations, and industry trends.


Overview of API Components in STALEVO 75

Entacapone

Entacapone inhibits catechol-O-methyltransferase (COMT), extending the half-life of levodopa. It is a selective, reversible COMT inhibitor with molecular formula C13H18N4O5.

Levodopa

Levodopa (L-DOPA) is a dopamine precursor critical for symptom management in Parkinson’s. Its molecular formula is C9H11NO4.

Carbidopa

Carbidopa enhances levodopa’s central nervous system availability by inhibiting peripheral decarboxylation, with a molecular formula of C12H14N2O4.

Industry Trends and Challenges in API Sourcing

Globalization of Supply Chains

The supply chain for APIs, especially from China and India, continues to expand, offering cost-advantages but raising concerns regarding quality consistency and regulatory compliance. Many Western manufacturers are now integrating Quality by Design (QbD) principles and audit programs to monitor suppliers.

API Policy and Regulatory Dynamics

Stringent regulations post-2019, especially during the COVID-19 pandemic, emphasize the need for robust quality control and transparency in API sourcing. Countries are promoting on-shore manufacturing and developing strategic API reserves.

Supply Chain Disruptions

Pandemic-related logistics and geopolitical issues increasingly threaten API continuity, prompting manufacturers to diversify suppliers and establish dual sourcing paths.


Conclusion

The procurement of APIs for STALEVO 75 involves a complex network of global suppliers committed to maintaining quality and compliance. Leading Chinese and Indian manufacturers dominate the market, offering competitively priced, GMP-compliant APIs. Strategic partnerships and rigorous due diligence are essential for pharmaceutical companies to ensure the integrity of their supply chains and maintain regulatory approvals worldwide. As the industry evolves, embracing diversification, technological innovation, and transparent supplier audits will be critical to ensuring continuous, high-quality API supply for Parkinson’s disease therapies.


Key Takeaways

  • Secure API sources from GMP-certified, regulatory-compliant suppliers with verifiable documentation.
  • Diversify supply chains to mitigate risks from geopolitical or logistical disruptions.
  • Prioritize suppliers with proven track records in high purity and consistent quality for APIs used in CNS treatments.
  • Monitor industry trends toward on-shoring and strategic API reserves to safeguard supply stability.
