Abstract

Objective: To enhance the solubility of poorly soluble drugs by using 23 factorial design in the formulation of fast dissolving tablets by employing starch oxalate as a superdisintegrant.


Methods: Starch oxalate was synthesized by gelatinization process. The physical and micromeritic properties were performed to evaluate the synthesized starch oxalate. By using 23 factorial design, atenolol fast dissolving tablet was prepared by employing starch oxalate as a superdisintegrant in different proportions in each case by direct compression method. In the evaluation of fast dissolving tablets the drug content, hardness, friability, disintegration time and other dissolution characteristics were utilized.


Results: The starch oxalate prepared was found to be fine, free-flowing completely amorphous powder. The compatibility between atenolol and starch oxalate were studied and showed no interaction. The drug content, hardness, and friability have been effective with regard to all the formulated fast dissolving tablets employing starch oxalate. The optimised formulation F8 has the least disintegration time i.e., 24±0.06s. The In–vitro wetting time was less (i.e., 28s) in optimized formulation F8. The water absorption ratio of the formulated tablets was found to be more in F8 formulation 94.42±0.18%. The cumulative drug dissolved in the optimized formulation F8 was found to be 98.70±0.24% in 5 min.


Conclusion: The dissolution efficiency of atenolol was enhanced when starch oxalate was found to be a superdisintegrant when combined with sodium starch glycolate, crospovidone and, hence to provide immediate release of the formulated fast dissolving tablets contained drug it could be used.
