Abstract

Coatings on tablets must be stable and strong enough to survive the handling of the tablet, must not make tablets stick

together during the coating process, and must follow the fine contours of embossed characters or logos on tablets.

Coatings can also facilitate printing on tablets, if required. Coatings are necessary for tablets that have an unpleasant

taste, and a smoother finish makes large tablets easier to swallow. Tablet coatings are also useful to extend the shelf-life

of components that are sensitive to moisture or oxidation. Opaque materials like titanium dioxide can protect light

sensitive actives from photo degradation. Special coatings (for example with pearlescent effects) can enhance brand

recognition. Such coatings onto the tablets also serve the stand alone brand identity to the reputed producers as well. So

taking into the consideration in this review a deep insight has been given about the formulation and evaluation of gelatin

enrobed tablets and its various designing constraints also been discussed.
