An Active Pharmaceutical Ingredient(API) is the primary component in a drug that produces the intended therapeutic effect. It is the biologically active substance responsible for treating or preventing disease. APIs are manufactured through chemical synthesis, fermentation, or biotechnology and are combined with excipients (inactive ingredients) to create the final medicinal product. High purity, consistency, and regulatory compliance are essential in API production to ensure safety and effectiveness.
