Poor aqueous solubility of an active pharmaceutical ingredient (API) is a significant hurdle during drug development. Delivering a drug in its amorphous solid-state is a potential method to overcome this issue, since the amorphous form has increased apparent aqueous solubility. However, the amorphous state is only metastable, and is thermodynamically driven to recrystallize. As a result, pure amorphous drugs are seldom used in marketed products. Intimately mixing a drug in its amorphous form with a polymer, known as an amorphous solid dispersion (ASD), has the potential to significantly extend the physical stability of the amorphous form, while maintaining the benefit …
