Pharmaceutical excipients are substances that are included in a pharmaceutical dosage form not for their direct therapeutic action, but to aid the manufacturing process, to protect, support or enhance stability, or for bioavailability or patient acceptability. They may also assist in product identification and enhance the overall safety or function of the product during storage or use.
Ideal Excipient Properties :
• Stable and Reproducible
• No unwished interaction with drug
• Pharmacologically inert
• Desired functionality
• Cost effective
