COMPARATIVE FORMULATION, EVALUATION AND OPTIMIZATION OF IMIDAPRIL MOUTH DISSOLVING TABLETS USING DIFFERENT SYNTHETIC SUPERDISINTEGRATING AGENTS
Objective: The aim of this work was preparing once daily mouth disintegrating tablets to handle easily for adult hypertensive patients who have difficulty in swallowing.
Methods: Imidapril mouth dissolving tablets (MDTs) were prepared by direct compression method using different concentrations of synthetic super disintegrants namely Sodium starch glycolate, Croscarmellose sodium & Kyron T-314. The prepared tablets were evaluated for weight variation, thickness, hardness, friability, content uniformity, disintegration time and In-vitro dissolution studies.
Results: The micropolitics study indicates that all formulations were of acceptable to good flowability. Tablet hardness and friability indicated that the prepared formulations were having good mechanical strength. The most satisfactory formulation F5 containing Sodium starch glycolate showed minimum disintegration time of 19 s and released a maximum amount of drug in 30 min in phosphate buffer 6.8pH, by an appropriate combination of excipients. The optimized F5 formulation containing Sodium starch glycolate was found to be stable during stability studies conducted for 3 mo as per International Conference on Harmonization (ICH) guidelines.
Conclusion: The present study conclusively proved that Imidapril MDTs could be successfully developed using various super disintegrants. The prepared tablets gave promising results with respect to the faster release of Imidapril. Further clinical studies are suggested to confirm the ability of the best-achieved system to avoid the first pass metabolism of Imidapril and improve patient compliance.
