ABSTRACT

Tablet coating is one of the oldest pharmaceutical processes still is existence. The advantages of tablet coating are taste masking, odor masking, physical and chemical protection, protects the drug in the stomach and to control its release profile. Control and sustain the release of the drug from the dosage form. Increase the mechanical strength of the dosage form. There are discusses the several techniques for tablet coating which include sugar coating, film coating and enteric coating. The disadvantages of the older techniques of coating have been overcome with the recent advancement in coating technologies. In these latest technologies coating materials are directly coated on to the surface of solid dosage forms without using any solvent various solvent less coatings are available such as electrostatic dry coating, magnetically assisted impaction coating, compression coating, powder coating and fluid bed coating, supercell coating. Magnetically assisted impaction coating, electrostatic dry coating, coating and Supercell coating technology also are available latest technique of coating. An ideal tablet should be free from of the visual functional defect. This review deal in detail approximately records, recent tablet coating technique and remedies associated with the tablet coating. In these review are also discusses the coating solution and evaluation.

Keywords: Tablet coating, magnetically assisted impaction coating, supercell coating, electrostatic dry coating, compression coating.
