Thiazolidinediones: A Type 2 Diabetes Medication

Thiazolidinediones is a category of medications used to treat Type 2 Diabetes. It works extremely well when used in conjunction with healthy diet and exercise. Some medications that fall in this category include Actos, Avandia and Avandamet.

How do they work?
Thiazolidinediones work by reducing the insulin resistance in the body. As a result, the body is in a better position to respond to the insulin. This helps maintain normal blood sugar levels. However, they do not help the body to produce more insulin. Also, this medication does not work as a replacement for insulin. It just works as a substitute for a healthy diet that is ideally recommended for diabetics, by the doctors.

Usage
Thiazolidinediones are oral medications. They may be used alone or along with other diabetes medications. For increased effectiveness, it is important that the medicines be taken every day. Thiazolidinediones may take up to three months to show full effect. Also, do not stop using them unless asked to do so by your health care provider.
