Component Specifications

Definition
Active Pharmaceutical Ingredient (API) is the substance in a pharmaceutical drug that produces the intended pharmacological effect. In tablet manufacturing, APIs are combined with excipients through processes like granulation, blending, and compression to form the final dosage form. APIs must meet strict purity, potency, and stability standards as defined by pharmacopeias and regulatory agencies.
Working Principle
APIs work through specific biochemical interactions with biological targets (e.g., receptors, enzymes) to produce therapeutic effects. In tablet formulation, APIs are uniformly distributed within excipient matrices to ensure consistent dosage delivery upon ingestion and dissolution.
Materials
APIs are typically organic compounds (small molecules) or biologics (proteins, peptides) with defined chemical structures. Common materials include synthetic chemicals, plant extracts, or fermentation products. Specifications include chemical purity (>98-99.5%), particle size distribution (10-200 μm), polymorphism control, and moisture content (<0.5%).
Technical Parameters
  • Purity ≥98.5%
  • Potency 95-105% of labeled amount
  • Stability 24-month shelf life under specified conditions
  • Solubility Water-soluble or lipid-soluble as required
  • Bulk Density 0.4-0.8 g/cm³
  • Particle Size D90 < 150 μm
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 pure drug substance that provides therapeutic effect, while finished dosage form (like tablets) contains API combined with excipients for administration.

How are APIs tested for quality?

APIs undergo rigorous testing including identity, assay, impurity profiling, residual solvents, microbial limits, and physical characterization per pharmacopeial standards.

What are common sources of APIs?

APIs are sourced from chemical synthesis, fermentation, extraction from natural sources, or recombinant DNA technology for biologics.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
