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.
Highlights • Cilostazol has low oral bioavailability due to poor aqueous solubility. • Cilostazol was loaded in nanoemulsion formulations. • Developed formulation possessed good physical stability. • Drug loaded nanoemulsion enhances permeation of drug through membrane. • Nanoemulsion showed increase in oral bioavailability of drug.
