HPMC – Hydroxypropylmethylcellulose
Gastroretentive systems for prolonged release of metformin based on osmotically driven expansion
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…

Hydroxypropyl Methylcellulose—A Key Excipient in Pharmaceutical Drug Delivery Systems
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,…

Hydroxypropyl-β-Cyclodextrin-Enhanced Azelaic Acid Hydrogel for Acne Treatment: Evaluation of…
Abstract
Purpose
Azelaic acid (AZE) is a widely used agent in acne treatment, but its poor water solubility limits its therapeutic potential. In this study, the effectiveness of azelaic acid (AZE)—a compound with limited therapeutic efficacy due to its poor water solubility—was investigated in…

Guiding excipient selection for physically stable Amorphous Solid Dispersions: A combined in-vitro…
Abstract
Fast screening of amorphous solid dispersions (ASDs) is a need in the pharmaceutical industry. To support this, several emerging technologies have been developed ranging from in-silico prediction to miniaturized high-throughput experimentation. However, a notable challenge lies in the…

Combining high-throughput ASD screening with the rDCS to streamline development of poorly soluble…
Abstract
Poor aqueous solubility and slow dissolution rate of active pharmaceutical ingredients (APIs) are often encountered challenges during oral drug development, leading to variable and insufficient bioavailability. To overcome these challenges, a so-called “enabling” formulation strategy is…

Predicting the tabletability of binary powder mixtures from that of individual components
Abstract
Predicting the tabletability, i.e., the relationship between tensile strength and compaction pressure, of powder mixtures based on that of pure materials would streamline tablet formulation development, saving both time and materials. This would be a significant step toward achieving…
