Abstract

Film coating is the process of application of a thin, uniform layer or film of polymeric material on the surface of the tablet. Tablet coating is one of the oldest pharmaceutical processes still in existence. Now days different organic and aqueous solvents are used in coating. There are various polymers from different chemicals characteristics are used for film coating; e.g. vinyl polymers, cellulose ethers, silicones etc. But many of the organic solvents are toxic in nature and causes problem in coating. Use of water over organic solvent is economic. Polymers and solvents are one of the important parts of coating. Coating also alters release of medicament and solubility. The main aim of review is to understand advantages and problems in aqueous film coating.

Keywords: Aqueous film coating, Polymers, Solvents, Coating process parameters.
