Component Specifications

Definition
Active Pharmaceutical Ingredient (API) refers to the substance or mixture of substances in a pharmaceutical drug that is biologically active and responsible for the therapeutic effect. In pharmaceutical manufacturing, APIs are synthesized, extracted, or purified through controlled chemical, biological, or biotechnological processes to meet strict purity, potency, and stability standards. They form the core component of finished dosage forms such as tablets, capsules, or injectables.
Working Principle
APIs work by interacting with specific biological targets (e.g., receptors, enzymes) in the body to modulate physiological processes. Their efficacy depends on chemical structure, solubility, bioavailability, and pharmacokinetic properties. In manufacturing, APIs are produced under Good Manufacturing Practice (GMP) conditions to ensure consistency, purity, and compliance with regulatory standards.
Materials
High-purity chemical compounds, biologics (e.g., proteins, antibodies), or natural extracts. Common materials include small molecules (e.g., aspirin, ibuprofen), peptides, and recombinant proteins. Excipients are not included.
Technical Parameters
  • Purity ≥98% (typically 99-100% for critical APIs)
  • Potency Specified in mg/g or IU/mg
  • Stability Shelf-life ≥24 months under recommended storage
  • Particle Size Controlled (e.g., 10-200 μm)
  • Moisture Content <0.5%
  • Residual Solvents Per ICH Q3C guidelines
Standards
ISO 9001, ISO 13485, ICH Q7, USP, EP, JP

Frequently Asked Questions

What is the difference between API and finished dosage form?

API is the active substance that provides therapeutic effect, while finished dosage form (e.g., tablet) includes API plus excipients for delivery, stability, and patient compliance.

How are APIs manufactured?

APIs are produced via chemical synthesis, fermentation, extraction from natural sources, or recombinant DNA technology, followed by purification, drying, and milling under GMP conditions.

What regulations govern API production?

API manufacturing follows ICH Q7 GMP guidelines, regional pharmacopoeias (USP, EP), and regulations from agencies like FDA (US) and EMA (EU).

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
