Fast dissolving tablets

ABSTRACTPantoprazole is a proton pump inhibitor that decreases the amount of acid produced in the stomach mainly used to treat erosive esophagitis and other condition involving excess stomach acid such as Zollinger-Ellison syndrome. The objective of present study was to Formulate and Evaluate fast dissolving tablets of Pantoprazole sodium. In the preformulation study, IR Spectra of pure drug and with different polymers showed no interaction (no shift in peak). To enhance faster disintegration rate, super disintigrants such as croscarmallose sodium, Crospovidone and Sodium starch glycolate were tried. To evaluate their role in fast dispersion, they were used in different concentrations hence in the present study 9 formulations were prepared. The prepared tablets were subjected to various parameters like uniformity of weight, hardness, friability, drug content, water absorption ratio, wetting time, in vitro disintegration time and in vitro dissolution studies. The effect of different super disintigrants over the Drug release profile was investigated. In the study, all powder blends showed good flow ability (angle of repose below 30º), bulk density in the range between 0.33-0.37 g/cm3 tapped density in the range between 0.34 and 0.39 g/cm3, and the compressibility index was found to be between 5.83 and 9.98 %, which ensures the blend that may be suitable for direct compression in to tablets. In vitro disintegration time for all formulation batches i.e. F-1 to F-9 showed wide variation in the range between 8.78.64 to 19.35 seconds and % Drug dissolved at 30 seconds. The prepared tablets exhibited satisfactory physico-chemical characteristics. The prepared formulations containing superdisintegrants, Crospovidone Along with microcrystalline cellulose showed faster dispersion and dissolution profile as compared with other two superdisintegrants containing formulations. Moreover, the  study revealed Crospovidone showed satisfactory results than the superdisintegrants like c

The aim of present work was to develop fast dissolving tablets of Valsartan by direct compression method using different binders such as acacia, sucrose, starch, gelatin, hydroxypropyl methylcellulose (HPMC) H7509, and Polyvinyl-pyrrolidone (PVP). During the compression of tablets, binders keep the composition of these fast dissolving tablets together. The right selection of binder or combination of these is essential to maintain the integrity and stability of the tablet. The prepared tablets were evaluated for parameters such as hardness, friability, drug content, weight variation, wetting time, water absorption ratio, in-vitro disintegration time, in vitro dissolution studies and stability studies. The study reveals that formulations prepared by direct compression (F5) exhibits better dissolution (90.57%) with lowest disintegration time (40 seconds) containing sucrose as binding agent.
