RESUMO
Objective of present study was to enhance patient compliance in pediatrics and geriatrics patients of Hypertension. To achieve this target, innovative orodispersible tablets of atenolol and atorvastatin was developed to produce instant action by rapidly disintegrating into oral cavity. Three different techniques like direct compression, effervescent and sublimation methods were used to prepare these tablets (Five batches of tablets by each method) by using two superdisintegrants like Sodium starch glycolate and pregelatinized starch alone and in combination. Pre-formulation studies including rheological analysis (Bulk density, tapped density, Angle of repose, Carr's compressibility index, Hausner's ratio), compatibility studies such as Fourier transform infrared spectrophotometry (FTIR) and Differential scanning colorimetry (DSC), Post-compression and stability studies were also performed. Finally, results were statistically evaluated by the applying one way ANOVA test and mean. It was concluded that the formulation F8 containing Sodium starch glycolate 2% and pregelatinized starch 6% found best regarding disintegration time, wetting volume, wetting time, release studies etc. The order in which drug release was quicker is Pregelatinized starch plus Sodium starch glycolate > Pregelatinized starch > Sodium starch glycolate (primojel). It was concluded that sublimation method was the best among three methods used for orodispersible tablets formulations.
