What is the Role of Excipients in the CAPEX Drug?
Excipients are inactive substances used in drug formulations to stabilize active pharmaceutical ingredients (APIs), improve manufacturability, and enhance patient experience. For CAPEX, a drug identified primarily by its chemical name or code, excipients influence formulation stability, bioavailability, delivery method, and shelf life. They also impact manufacturing efficiency and regulatory compliance.
What Are Key Factors in Excipient Strategy for CAPEX?
Selection Criteria
- Compatibility: Ensures excipients do not react with APIs or other excipients.
- Functional Requirements: Depends on the dosage form—tablets, injections, or topical.
- Stability: Excipients must maintain chemical and physical stability of the final product.
- Regulatory Status: Use excipients with established safety profiles according to FDA or EMA guidelines.
- Supply Chain Security: Reliable sourcing to prevent manufacturing disruptions.
