Abstract Metformin is a relatively old drug mainly used to treat type 2 and gestational diabetes, which needs to be administered two or three times a day in high doses. It has a high aqueous solubility and is poorly absorbed following oral intake. Aiming to achieve a gastroretentive formulation for…

Abstract The taste of a drug impacts the compliance of patients for oral administration. In this study, the bitter taste of diclofenac sodium (DS) was masked with purolite A430MR through ion exchange. The DS-A430MR complexes (DACs) were prepared at a 1:1 (w/w) drug to resin through a simple aqueous…
