Active Pharmaceutical Ingredient (API)
Active Pharmaceutical Ingredient (API) — The biologically active component in a formulation responsible for producing the intended effect. In peptide research, refers to the synthesized peptide itself.
What Is an API?
An active pharmaceutical ingredient (API) is the biologically active compound in a drug product responsible for the therapeutic effect. For peptide therapeutics, the API is the purified peptide itself, characterized by its amino acid sequence, purity, net peptide content, and counterion form. The API is combined with excipients to create the final drug product.
Peptide API Requirements
- Identity: Confirmed by MS, AAA, and peptide mapping
- Purity: Specified limits for individual and total impurities (deletions, degradation products)
- GMP compliance: Manufactured under cGMP with full batch documentation
