Excipients are inactive ingredients that are used in the formulation of pharmaceutical products. They serve a variety of functions, including acting as a vehicle for the active ingredient, improving the stability and bioavailability of the product, and providing desired physical and chemical properties.

There are many different types of excipients, including fillers, binders, lubricants, and disintegrants, to name a few. The selection of excipients is an important aspect of formulation development, as they can significantly impact the performance and stability of the final product.

In addition to their functional properties, excipients also play a role in the physical characteristics of the product, such as its appearance, texture, and taste. This is important for patient compliance, as patients are more likely to take a medication that is easy to swallow and has a pleasant taste.

Excipients can also be used to mask the taste of an active ingredient, making it more palatable for patients. This is especially important for children or patients who may have a hard time swallowing pills or capsules.

Overall, excipients play a critical role in the formulation of pharmaceutical products. By carefully selecting and using excipients, companies can develop products that are safe, effective, and suitable for their intended use.
