Recent trends in pharmaceutical technologies are towards the development of coating methods which overcomes the various disadvantages associated with solvent based coatings. In these newer technologies coating materials are directly coated onto solid dosage forms without using any solvent and then cured by various methods to form a coat, hence these methods sometimes called as solventless coatings. Various solventless coatings are available such as photocurable coating, magnetically assisted impaction coating, compression coating, hot melt coating, powder coating, electrostatic dry coating, supercritical fluid coating, herein only magnetically assisted impaction coating and electrostatic dry coating are discussed. This review summarizes the fundamental principles and coating processes of various dry coating technologies.
