Formulation Strategies
- Utilize high-purity excipients to reduce regulatory hurdles.
- Optimize excipient ratios to improve manufacturability and drop-weight uniformity.
- Incorporate multifunctional excipients (e.g., disintegrant and binder) to streamline formulations.
- Consider coated or functional excipients for targeted release profiles.
How does excipient selection affect manufacturing and regulatory pathways?
- Manufacturing Efficiency: Using excipients with high flowability and compressibility enhances throughput and reduces costs and rejects.
- Stability and Shelf Life: Excipients influence moisture content, degradation pathways, and chemical stability.
- Regulatory Approval: Regulatory bodies require excipient safety data; novel excipients increase approval timelines. Using well-established excipients shortens approval and market entry.
