Supply Chain and Quality Assurance Considerations

• Regulatory Compliance: Procurement from manufacturers compliant with cGMP, and with global regulatory approvals such as FDA, EMA, or WHO prequalification.
• Quality Documentation: Certificates of Analysis (CoA), Batch Records, and stability data are essential.
• Supply Risks: Political, logistical, or regulatory changes can disrupt sourcing; diversification of suppliers reduces vulnerability.
• Manufacturing Capacity: Consider API production capacity relative to demand, especially in the context of COVID-19-induced supply chain disruptions.

---

Strategic Sourcing Approaches

• Vertical Integration: Collaborate directly with manufacturers to streamline supply chains.
• Long-term Contracts: Secure supply stability and pricing predictability.
• Regional Sourcing: Leverage nearshoring opportunities to reduce lead times.
• Quality-focused Due Diligence: Continuous audits, supplier qualification, and track record assessment.

---

Regulatory and Intellectual Property Landscape

• Many API manufacturers operate within a complex regulatory environment, necessitating due diligence on their compliance status.
• Patent considerations are less restrictive for APIs like levonorgestrel and ethinyl estradiol, which are often off-patent, but formulation-specific patents may impact manufacturing rights and sourcing.

---

Emerging Trends and Future Outlook

• Growing demand for biosimilar and branded generic APIs presents opportunities for diversification.
• Technological advances in API synthesis and purification processes aim to improve quality, reduce costs, and enhance supply resilience.
• Increased regulatory scrutiny encourages manufacturers to uphold high standards, particularly amid global health crises.
