In the present research work pulsatile drug delivery system of Methylphenidate tablets were formulated by employing compression coating technology. Initially the core tablets were prepared by using various concentrations of super disintegrates , the formulated core tablets were coated with the polymers by using compression coating technology. All the core and press coated tablet formulations were subjected to various physical and chemical evaluation tests for core and press coated tablets. The thickness, hardness and weight variation shown by all the tablet formulations were found within the official pharmacopoeia limits. In vitro release of Methylphenidate of core tablet formulations F1-F12, F4 showed faster drug release within 30 mins. Hence it was selected as optimized core formulation for coating purpose. The core tablet is being coated with six coating formulations by using press coating technique. Among the six formulations C3 shown maximum drug release hence it was considered as the optimized formulation.
