The use of amorphous solid dispersions (ASD) to overcome poor drug solubility has gained interest in the pharmaceutical industry over the past decade. ASDs are challenging to formulate because they are thermodynamically unstable, and the dispersed drugs tend to recrystallize. Until now, most research on ASDs has focused on immediate-release formulations, supersaturation, and stability; only a few studies have recently reported on the manufacturing of sustained-release ASDs.

The process of mucoadhesion has been widely studied using a wide variety of methods, which are influenced by instrumental variables and experiment design, making the comparison between the results of different studies difficult. The aim of this work was to standardize the conditions of the detachment test and the rheological methods of mucoadhesion assessment for semisolids, and introduce a texture profile analysis (TPA) method.

Results of experiments on prolonged release of paracetamol from polymer matrix tablets with cross-linked poly(acrylic acid) Carbopol®Ultrez 21 as the prolonging polymer were reported. The effects of factors such as tableting technology, type of alkaline agent, and ratio of Carbopol® to alkaline agent on paracetamol release kinetics were studied. It was established that matrices prepared by wet granulation had the best potential for prolonging the release. The ratio of Carbopol®to alkaline...

ABSTRACT The study carried out here was focused on developing conventional monolithic controlled release matrix tablet of Atorvastatin calcium using carbomer as release controlling polymer. This system ensures the drug release at the alkaline pH region where the drug has got maximum solubility. Further the study was concentrated on comparing the impact of gelling agent polyvinyl pyrrolidone on drug release. Quality by design tools were considered during formulation development and the polymer...

Abstract The oral delivery of mucoadhesive patches has been shown to enhance the absorption of large molecules such as peptides. We hypothesized that this mechanism could have utility for poorly soluble small molecules by utilizing a mucoadhesive polymer as the matrix for an amorphous solid dispersion. Binary dispersions of itraconazole and carbomer (Carbopol 71G) were prepared utilizing a thermokinetic mixing process (KinetiSol Dispersing) and the physicochemical properties were investigated...
