API

An Active Pharmaceutical Ingredient (API) is the core component of a pharmaceutical drug that produces the intended therapeutic effect. APIs are responsible for diagnosing, treating, curing, or preventing diseases, while excipients are inactive substances that support the drug’s delivery and stability. In the pharmaceutical industry, APIs can be derived from chemical synthesis, fermentation, biotechnology, or natural sources. The quality, purity, and consistency of APIs are critical, as they directly impact the safety and efficacy of medicines. API manufacturing follows strict regulatory guidelines such as Good Manufacturing Practices (GMP) to ensure compliance with global health authorities. APIs may be produced in bulk and supplied to formulation companies or integrated into finished dosage forms like tablets, capsules, and injections.
