Formulation and Evaluation of Controlled Release Matrix Tablets of Cefixime Trihydrate

Abstract: The main objective of the present work was to develop sustained release matrix tablets of Cefixime Trihydrate were prepared by direct compression techniques and evaluates the effect of formulation variables such as lubricant, binder, polymer content and viscosity grades of HPMC on the behavior of Cefixime Trihydrate release. The prepared tablets were evaluated for various physico-chemical parameters. In vitro release profile was check to evaluate the sustained release matrix tablet of Cefixime Trihydrate. The drug release from the optimized formulation was found to follow zero order kinetics. Thus the phenomenon of drug release showed that the release of optimized formulation is controlled by diffusion. Administration of Cefixime Trihydrate in a sustained release dosage would be more desirable for bacterial infections effects by maintaining the plasma concentrations of the drug well above the therapeutic concentration. From In vitro dissolution profile, Formulation S3 was prepared with Hydroxypropyl methylcellulose (K15M) combination where drug release was about 99.14% at the end of 24 hrs and followed zero order with non-Fickian diffusion method. It is selected as the best formulation.
