Excipients are natural/ synthetic substances formulated alongside active ingredient of a medicine. These are included for bulking-up formulations which contain potent active ingredients.

Pharmaceutical Excipients are also useful in manufacturing process & aid in the handling of active substance concerned like by facilitating powder flow or non-stick properties while also aiding in vitro stability.

Pharmaceutical excipients are the substances included in the pharmaceutical dosage not for their direct therapeutic action but to aid the manufacturing process as well as to protect and enhance stability. These are also helpful in bioavailability or patient acceptability. Thousands of excipients are widely used in almost 90% of medicines and make up products.
