Drug Formulation

A Catalyst article describing how a medical drug is made into a form which works well in the body. Medicines rarely contain just one pure chemical substance. The vast majority are made of a complex mixture that contains an active ingredient (the compound that has the desired effect in the body) and compounds called excipients. This mixture is known as a formulation. The article looks at what excipients are, why they are included in drugs and how the formulations are designed.

This article is from Catalyst: GCSE Science Review 2009, Volume 20, Issue 1.
