Formulation and Evaluation of Gastro retentive Effervescent Floating Tablets of Famotidine: Effect of Formulation Variables and In Vitro In Vivo EvaluationBy R. Narayana Charyulu, Shaiju S Dharan, Mudit Dixit
Abstract: Gastro retentive effervescent floating tablets of famotidine were developed in an attempt to sustain the drug release as well as to prolong the presence of dosage form in the stomach or upper small intestine until drug is completely released in desired period of time from the formulation with special emphasis to the effect and concentration of different polymers on drug release and floatation. Tablets were prepared by direct compression method …

Formulation and Evaluation of Gastroretentive Bilayered Floating Tablets of Famotidine: Effect of Formulation Variables and in vitro in vivo EvaluationBy Shaiju S Dharan, R. Narayana Charyulu
Abstract: The present investigation concerns the development of bilayered floating tablets of famotidine for prolongation of gastric residence time. An attempt was made to prepare bilayered floating tablets of famotidine by direct compression method. Two layered formulations were designed with an immediate release layer (IR) comprising of the drug, the super disintegrant Croscarmellose sodium along with the other diluents like microcrystalline cellulose and dicalcium phosphate. Three batches of immediate release layer …
