Pharmaceutical Excipients

Pharmaceutical excipients are crucial ingredients used in the formulation of pharmaceuticals to improve their stability, efficacy, and acceptance by patients. These ingredients play a crucial part in the creation and administration of medications as inert additives. They are often carefully chosen for their compatibility with active pharmaceutical ingredients (APIs) and their capacity to provide the final dosage form with a variety of desirable properties. Pharmaceutical excipients are a broad category of compounds that include, among others, binders, diluents, lubricants, disintegrants, and flavoring ingredients.
