Excipient
Excipient
Excipient (/ɪkˈsɪpiənt/) is a substance that is included in a medication to facilitate the drug's delivery. The term is derived from the Latin word "excipere," which means "to take out."
Definition
An excipient is a pharmacologically inactive substance used as a carrier for the active ingredients of a medication. In other words, it is a substance that is included in a drug to facilitate its delivery. Excipients can also be used to aid the process of drug absorption or to improve the taste or appearance of a medication.
Types of Excipients
There are several types of excipients, each with a specific role in the formulation of a drug. These include:
- Fillers: These are used to bulk up the formulation, making it easier to handle and consume.
- Binders: These help to hold the ingredients together, ensuring that the drug remains intact until it reaches the desired location in the body.
- Disintegrants: These help the drug to break down into smaller particles, aiding in its absorption.
- Lubricants: These help to prevent the drug from sticking to the machinery during production.
- Coatings: These are used to protect the drug from the environment, improve its appearance, and mask any unpleasant tastes or odors.
Uses
Excipients are used in a variety of pharmaceutical applications. They can be used to improve the taste or appearance of a drug, to aid in its absorption, or to ensure that it remains stable during storage. Excipients can also be used to control the release of a drug, ensuring that it is delivered to the body at the right time and in the right amount.
