What are excipients?
Excipients (or inactive ingredients) are ingredients used to transform active compounds into dosage forms suitable for administration. All pharmaceutical or nutritional products – whether they are tablets, capsules, liquids, vaccines or other – contain excipients. It is simply not possible to formulate these products without using binders, fillers, stabilizers and/or disintegrants.
Pharmaceutical excipients are substances other than the active pharmacological ingredient (API) which are included in the manufacturing process. Excipients are added to support the manufacturing process, to protect, support or enhance stability, or for bioavailability or patient acceptability.
Choosing the right excipients is a key determinant of the quality and functionality of a pharmaceutical product.
