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.
