Tablet coating, an enduring pharmaceutical process, involves the application of a dry outer layer to confer specific benefits on the dosage form, such as taste and odor masking, physical and chemical protection, protects the drug from the gastric surroundings, and control over release profiles. This technique, applicable to various solid oral forms, including particles, powders, granules, crystals, pellets, and tablets, employs a sugar or polymeric coat. Traditional methods, like sugar coating, film coating, and enteric coating, were once prevalent, but recent advancements have circumvented their limitations. Modern coating technologies directly apply materials onto tablet surfaces without solvents, aligning with ICH guidelines advocating the avoidance of organic solvents for pharmaceutical safety. This comprehensive review elucidates the fundamental tablet coating concepts, types of coating, advantages, objective, recent technological strides, challenges encountered in the process, their solutions, and methods for coating evaluation.
