ABSTRACT
Tablet coating is one of the oldest pharmaceutical process still in existence. It is a process of applying a thin polymer based film to a tablet or granule containing the active pharmaceutical ingredient. Solid dosage forms are coated for a number of reason, e.g. to control the drug release profile, to mask the bitter taste of the drug. There are various techniques for tablet coating such as sugar coating, film coating and enteric coating. Earlier, sugar coating was adopted for pharmaceutical as from the confectionary industry. But it was a tedious process and required skilled manipulation, therefore film coating was started to prefer over sugar coating. Film coating was mainly based on the solution of different polymers in organic and aqueous solution.
