Taste masking of oral pregabalin liquid preparation by using ion exchange resins

Abstract

The purpose of this study was to use cation exchange resins to mask Pregabalin's unpleasant taste. Dowex-50, a crosslinked polystyrene backbone, was employed. DRCs were synthesised in batches with drug-to-resin ratios of 1:1, 1:2, and 1:3. The optimal drug-to-resin ratio as well as the time required for maximum complexation were discovered. In this work, an attempt was made to develop a taste-masked Pregabalin solution using a simple, rapid, and cost-effective flavour masking approach, such as complexation among ion exchange resin, that could be acceptable to industries. To mask the flavour, researchers used a combination of ion-exchange resins such as doshion P 542, Tulsion 344, Indion 234, Indion 204, and Kyron T 114, as well as formulation into a solution. The generated suspensions were tested for taste, drug content, particle size, viscosity, sedimentation volume, drug release, and accelerated stability. Kyron T 114 has been shown to effectively disguise the drug among the various resins. The newly developed formulation also has the benefit of simplifying the manufacturing process and being cost-effective. According to drug release studies, the entire medicament was released within 20 minutes.
