Original Abstract

Nowadays in pharmaceutical research is problem that new chemical entities are poorly water soluble and therefore present a low dissolution rate. One approach to increase their solubility is to convert the crystalline form of a drug into the amorphous form. In this study, the co-amorphous IND-TRY mixtures were prepared by mechanical activation – ball milling. It was given different amount of polyvinylpyrrolidon to the mixture and was characterized. Solid - state properties were analyzed by dynamic mechanical analysis (DMA). It was found that addition of polyvinylpyrrolidon improved stability compared to the pure co-amorphous form. Glass transition state is growing with addition of PVP.
