Polymers are becoming very important in the drug delivery field. To control the drug release rate from the formulation, polymers are being used as the main tool. Polymers can be used as taste masking agents, to enhance stability of drug and to modify drug release characteristics. Biodegradable materials are used in medicine and other areas. In recent years there has been increase in use of biodegradable polymers. Biodegradable polymers are of two classes; synthetic and natural polymers. Natural polymers offer few advantages than synthetic polymers. Although polymers are used extensively as pharmaceutical packaging, this review is concerned with the use of polymers in the formulation of various dosage forms.
