In the present work, double walled microspheres of Tamoxifen (antiestrogenic drug) using Sodium alginate, Hydroxy propyl methyl cellulose (HPMC) K100,Guar gum, Xanthun gum were formulated to deliver Tamoxifen (TMX) through  oral route to treat breast cancer patients. Details regarding the preparation and evaluation of the formulations have been discussed in results. From the study following conclusions could be drawn. The results of this investigation indicate that Ion gelation method can be successfully employed to fabricate TMX microspheres. FT-IR spectra of the physical mixture revealed that the drug is compatible with the polymers and copolymer used. Microspheres containing sodium alginate along with HPMC in 1:1 ratio had a least size range of 610µm. Increase in the polymer concentration led to increase in % Yield, % Drug entrapment efficiency, Particle size. The  invitro drug release decreased with increase in the polymer and copolymer concentration. Among all formulations F7 shows Maximum drug release in 12 th hr  when compared with other formulations. Analysis of drug release mechanism showed that the drug release from the formulations followed the Non fickian diffusion mechanism and follows zero order kinectics. Based on the results of evaluation tests formulation coded F7 was concluded as best formulation.

Keywords : Tamoxifen, sodium alginate, HPMC, Microspheres, Diffusion, Copolymers,  Entrapment efficiency.
