Formulation And Evaulation Of Some Medicated Polymeric

The importance of pharmaceutical application of polymeric films was established for providing drug release from the desired dosage forms. These controlled release systems represent a relatively new development that evolves out of a continuing need to prolong and control drug administration . For instance , polymers can be used lo control the diffusion of drugs ; by controlling how rapidly the drug molecules move through the polymer film .The release rates for many drugs from polymeric films were significantly changed ifa) Different polymers were used in a mixture .b) The amount of drug in matrix was varied .c) Drug solubility was varied .d) Additives were included .e) Different solvents were used .Synthetic polymeric films have been widely used successfully in many pharmaceutical, industrial and medicinal applications. .
