The main objective of review is to collate the current literature on natural polymers being used for production of different floating systems which includes effervescent and non-effervescent systems. Natural polymers are versatile in characteristics, they are safe, non-toxic and inexpensive for use. All these characteristics of natural polymers make them suitable for Gastroretentive system. Natural polymers are widely investigated for their medicinal use and there more effectiveness than synthetic polymers. Thus, the present study focusses on the various polymers being utilized in floating drug delivery system. Use of polymers including guar gum, xanthan gum, tamarind gum, starch, pectin, okra has been reported by researchers to sustained the release of drug over prolonged period.
