Formulation and evaluation of immediate-release capsules of pregabalin

Abstract

The aim is to develop and evaluate capsules with various excipient compositions that satisfy the reference product's specifications to achieve an in-vitro correlation with the reference product after that. Pregabalin I.R. capsules were formulated using Corn starch, Dibasic calcium phosphate, Lactose anhydrous, and Avicel pH 102(Microcrystalline cellulose). After compatibility studies for the capsule blend were completed, the Drug was determined to be compatible with all excipients used in various formulations. After the blend was put into capsules, several metrics were examined, including average weight, disintegration, and assay. The formulation containing D.C.P. disintegrates at a faster rate than other formulations. It was discovered that the percentage of drug release in the F7 invitro dissolving profile was equal to that of the innovator product. Finally, it was concluded that the F7 formulation is better and similar to the innovator product.
