ABSTRACT
Tablets prepared by wet granulation method were found to be good without any chipping, capping and sticking. The hardness of the prepared tablets was found to be in the range of 4 to 5kg/ cm2. The friability values were found to be in the range of 0.50 to 0.72%. Disintegration time was found to be in the range of 1-3min. Formulation F6 showed good results than rest of the formulations in pre and post compression studies. The average weight and drug content of the prepared tablets indicate weight and drug content uniformity within the batches prepared. Formulation F6 (98.5%) displayed maximum drug release which shows similar drug release as that of F7, F8, but F7 and F8 were failed in mechanical properties like hardness and friability.IR-spectroscopic studies indicated that there is no drug–excipients interactions. The optimized formulation follows first order kinetics.
