ROLE OF NATURAL POLYMER IN SUSTAINED AND CONTROLLED RELEASE

Vaishali S. Kadam, G. R. Shendarkar

Now a day there has been an important development in different dosage forms for existing and newly designed drugs and natural products, and synthetic as well as semi-synthetic excipients always need to be used for a variety of purposes. Gums and mucilages are widely used as natural materials for conventional and novel dosage forms. With the increasing interest in polymers of natural origin, the pharmaceutical world has compliance to use most of them in their formulations. Moreover, the tremendous orientation of Pharmaceutical world towards these naturally derived polymers has become a subject of increasing interest to discover, extract and purify such compounds from the reported origin. These polymers such as natural gums and mucilage are bio-compatible, cheap and easily available and are preferred to synthetic and semi synthetic excipients because of their lack of toxicity, low cost, availability, soothing action and non irritant nature. In the present review gums and mucilage’s, used as a excipients as well as carrier for sustained or controlled release.
