Abstract

Formulation and development of Famotidine floating tablets for gastric irritation

Author(s): Abhishek Kumar Chauhan, Arun Kumar, Manish Kumar, Sachin Kumar, Sweta Singh

The purpose of the study was to prolong the gastric residence time of famotidine by designing its floating tablets and to study the influence of different polymers on its release rate. Three formulations of famotidine containing varying concentrations of polymers were designed by optimization. The floating matrix tablets of famotidine were prepared by direct compression method. The prepared tablets were evaluated for physicochemical parameters such as hardness, floating properties (floating lag time, floating time and matrix integrity), and drug content. The physicochemical parameters of formulated tablets were found to be within normal range. The floating lag time of all the formulations was within the prescribed limit (54 Sec). All the formulations showed good matrix integrity and retarded the release of drug for 12 hours. The drug release from F-II was found to follow zero order kinetics. It was also found linear in Higuchi�?¢�?�?��?�?�s plot, which confirms that diffusion is one of the mechanisms of drug release.
