Abstract :
The use of natural excipients to deliver the bioactive agents has been hampered by the synthetic materials. However advantages offered by these natural excipients are their being non-toxic, less expensive and freely available. Excipients are any component other than the active substances intentionally added to formulation of a dosage form Research in natural polymers has witnessed growing interest and attention. This is attributable to a number of factors which include their relative abundance, low cost, and biodegrable and eco-firendly profiles. Natural polymers are basically polysaccharides so they are biocompatible and without any side effects. This review discusses various natural polymers.
