HPMC – Hydroxypropylmethylcellulose

Abstract Amorphous solid dispersions (ASDs) make a significant contribution to enhancing the solubility of poorly soluble drugs. The incorporation of surfactants in ASDs serves not only to facilitate the preparation process but also to further enhance solubility and bioavailability. However, the…

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 Hydroxypropyl methylcellulose (Hypromellose, HPMC) is a well-known excipient used in the pharmaceutical and nutraceutical fields due to its versatile physicochemical properties. HPMC (derived from cellulose and obtained through etherification) varies in polymerization degree and viscosity,…
