Drugs are hardly administered as such but are almost always formulated into suitable dosages with the aid of excipients which serve various functions such as binding, lubricating, gelling, suspending, flavoring, sweetening agent and bulking agents. These excipients play a critical role in creation of medicines, help in preserving the efficacy, safety and stability for active pharmaceutical ingredient and ensure that they deliver their promised benefits to the patients. The polymers which are used in the pharmaceutical industrial process for the formulations are obtained from the synthetic, semi synthetic and natural sources. The utilization of the natural polymers is been increased day by day due to their attributability towards their relative abundances, low cost, biodegradable property and eco-friendly profiles along with this these natural polymers can also enhance the drug functionality and also helps in innovative drug formulation. The increasing research interests in this group of materials are indications of their increasing importance. It is believed that as technology and testing techniques advance, more understanding of their physicochemical nature would be gained that can enable them to be tailored for wider pharmaceutical applications than their synthetic counterparts. Today, the whole world is increasingly interested in natural drugs and excipients. Natural materials have advantages over synthetic materials because they are non-toxic, less expensive and freely available. Furthermore, they can be modified to obtain tailor made materials for drug delivery systems allowing them to compete with the synthetic products that are commercially available.
