FORMULATION AND EVALUATION OF FAST DISSOLVING TABLET OF APREPITANT BY USING NATURAL AND SYNTHETIC SUPERDISINTEGRANTS

Abstract

Objective: The present study was aimed to formulate fast dissolving tablets (FDTs) of Aprepitant (APT) using natural and synthetic superdisintegrants with the desired onset of action, increased bioavailability by reducing the frequency of dosage and also reduce the first-pass metabolism of the drug. Methods: In this research, the gum isolated from cordia dichotoma was investigated as super disintegrants in fast dissolving tablets (FDTs). The aprepitant tablets were prepared separately using cordia dichotoma (natural), sodium starch glycolate and croscarmellose sodium (synthetic) as superdisintegrants by direct compression method. The tablets were evaluated for various precompression and post-compression parameters. Results: The optimized formulation (APT F3) of cordia dichotoma (8%) showed satisfactory physicochemical properties, minimum disintegration time (34 seconds) and highest dissolution rate (86.52%) in 10 min than the other synthetic superdisintegrants. Also, the pharmacokinetic study of the optimized formulation showed effective results as compared with marketed product of aprepitant. Conclusion: The developed formulation can improve the onset of action as well as improve patient compliance.
