Fast dissolving tablet are the novel dosage form which is well accepted now a days by geriatric and pediatric patients as it does not need water to swallow. The aim of the present article is to study the natural poymers used in fast dissolving tablets. Natural polymers like Mangifera indica gum, Hibiscus rosa sinenses mucilage, dehydrated banana powder, orange peel pectin, Locust bean gum, improve the properties of tablet and used as binder, diluent, superdisintegrant, increase the solubility of poorly water soluble drug, decrease the disintegration time and provide nutritional supplement. Natural poymers are obtained easily from the natural origion and they are cost effective, non-toxic, biodegradable, eco-friendly, devoid of any side effect, renewable and also provide nutritional supplement. It is proved from the studies that natural polymers are more safe and effective than the synthetic polymers.
