The purpose of this research work was to develop oral sustained release matrix tablets using the combination of HPMC 4000 cps (methocel K4M CR) and xanthan gum (3:1), in order to probe the effect of these polymers on release mechanism from matrix tablets. The matrix tablets of Ketotifen fumarate were prepared by direct compression process using methocel K4M CR and xanthan. The dissolution profiles were carried out by USP apparatus 2 (paddle) at 50 rpm in 500 ml 0.1 N HCl and distilled water. A One way analysis of variance (ANOVA) was used to interpret the result. Statistically significant differences were found among the drug release profile from different matrices. At a higher polymeric content (70% of the total tablet weight), drug release from the combination of methocel K4M CR and xanthan gum (3:1) was slower. On the contrary, at a lower polymeric level (40% of the total tablet weight), the rate of drug release was prominent. The best-fit release kinetics was accomplished with the Higuchi model followed by the zero-order plot, Korsmeyer and Hixson Crowell equations. One formulation showed drug release is more controlled. The data obtained proved that the formulations are useful for a sustained release of ketotifen fumarate. From these formulations corresponded more controlled of the drug release by the higher polymeric level of methocel K4M CR & xanthan and vice versa. The release of the model drug from the higher combination of methocel K4M CR and xanthan gum  matrix tablets was prolonged. As a result, an oral release dosage form to evade the frequency of administration of such type of drug.
