Fast disintegrating tablet of Valsartan for the treatment of pediatric hypertension

Fast disintegrating tablets (FDTs) dissolve or disintegrate in the mouth without the need of additional water. The aim of the present study was to formulate FDTs of Valsartan for the treatment ofhypertension in children who could find difficulties in swallowing conventional solid dosage forms. The tablets were prepared by wet granulation technique. Superdisintegrants such as sodium starchglycolate (SSG) and crospovidone were optimized as 5% on the basis of least disintegration time. Different binders such as gelatin and HPMC k15m, at varying concentrations, were used along with theoptimized superdisintegrant concentration. All the formulations were evaluated for content uniformity, disintegration time, friability, hardness and in vitro dissolution. In addition, the antihypertensiveefficacy of optimized formulation(s) was investigated in vivo. The results of the physical parameters were found to be within the acceptable range. In vitro dissolution studiesshowed that increasing the concentration of superdisintegrant decreased the disintegration time, and thereby, promoted faster drug release from tablets. On the other hand, increasing binderconcentration adversely hindered drug release from the tested formulations. Of interest, optimized formulation(s) of Valsartan FDTs rapidly and efficiently reduced the blood pressure in hypertensiverats. Collectively, FDTs could represent a potential drug delivery vehicle for the management of pediatric hypertension, in tandem with, alleviating the problems encountered with the administrationof conventional oral solid dosage forms to children.
