An Overview on Film Coating Tablet

Abstract

Tablet dosage form is a common Pharmaceutical dosage form. Tablet coating advantages is masking taste, odour, and colour of the drug, Providing Physical, chemical Protection and bioavailability of active ingredient. In coating process polymer sprayed onto the free surface deposition of a thin, uniform film on the tablet. But that process required a skilled operation, various types of tablet coating include enteric coating, sugar coating and film coating. Development of film coated tablet has based on different types of polymer in various organic solvent system, aqueous system or hydro alcoholic system to prepare pharmaceutical solid dosage form. Film coating are dry blend of polymer, plasticizer and surfactants. A polymer used for film coating of tablets has great importance. This review focus on the basic concept tablet coating, coating techniques and various aspect on tablet coating.
