Design, Formulation and Evaluation of Fexofenadine HCl Immediate Release Tablets by Solid Dispersion Method using Solvent Evaporation Technique

Abstract

Currently, this study focuses on developing immediate-release Fexofenadine hydrochloride tablets. The Fexofenadine HCl tablets have super disintegrants that help to accelerate dissolution and bioavailability. Sodium lauryl sulphate, microcrystalline cellulose as filler, crospovidone, and sodium starch glycolate were used to make the tablets using a direct compression method (2-8 percent). Pre and post compressional parameters were used in the preparation of the tablets. The In-vitro disintegration study shows that as concentration of sodium starch glycolate is increased, there is an increase in the amount of time it takes for the solution to disintegrate, but at the same time, there is a decrease in the amount of time it takes for the solution to disintegrate when the crospovidone level is increased. When combined with the crospovidone tablet formulation, the test found that the resulting tablets broke down in approximately 3 to 6 minutes, with enough force to release the fragments but not to harm the friability of the product. It was found that Fexofenadine hydrochloride tablet, a fast-acting form of treatment for allergic rhinitis, could be formulated in an immediate-release form.
