Abstract


Objective: Development of sustained released tablets of flurbiprofen (FP) using an alternative technique to the traditional method of wet granulation process aiming to lower labor cost of the granulation process and formulating tablets with better characteristics.

Methods: Eight matrix tablets formulae of FP were prepared by the alternative technique. The various characteristics of FP prepared tablets were investigated and comparatively evaluated by FP tablets prepared by the traditional method. The release data was analyzed according to various kinetic equations. The ulcerogenic effects of some FP tablets formulae were evaluated.

Results: FP tablets prepared by the alternative technique displayed the best physical characteristics. All FP prepared tablets displayed good sustained-release patterns. FP tablets prepared by the traditional method showed a progress decrease in drug dissolution by increasing matrix concentration and hence, more matrix agent or multiple granulations was needed which makes granulation process to be difficult and cost. While, FP tablets prepared by the alternative technique displayed dissolution profiles with minimal differences in-between reflecting the low labor cost of granulation process where good sustained patterns could be obtained by a minor of the matrix agent. Histologically, the ulcerogenic effects of FP on the rats were highly reduced by FP tablets prepared by the alternative technique rather than others. The release kinetics of different prepared FP tablets displayed a coupled release pattern between diffusion and dissolution.

Conclusion: This work proved the potential of the alternative technique as an effective economic approach for formulating FP sustained released tablets with better characteristics and low labor cost.

Keywords: Flurbiprofen, Sustained release, Matrix tablets, Alternative technique and dissolution.
