ABSTRACT
Pharmaceutical nonactive excipients have long been applied in a variety of pharmaceutical dosage forms to provide a wide range of functional characteristics that facilitate the optimal delivery of a drug to achieve the desired therapeutic effects. Pharmaceutical excipients are inert materials with no adverse effects on the safety and efficacy of therapeutic products. The Food and Drug Administration (FDA) website (1) provides a database listing all the FDA-approved nonactive pharmaceutical excipients. This provides formulation scientists a useful reference for efficient choices of the suitable excipients for the desired formulations of drug.
