The colon targeted drug delivery has a number of important implications in the field of pharmacotherapy. Oral colon targeted drug delivery of insulin has recently gained attention. Targeting of insulin to the colon via oral administration protect the insulin from degradation or release in the stomach and small intestine. It also ensures abrupt or controlled release of the insulin in the proximal colon. Various drug delivery systems have been designed that deliver the drug quantitatively to the colon and then trigger the release of drug. This review will cover different types of Eudragit polymers which can be used in formulation of colon targeted drug delivery systems.
