Emulsion-templated freeze-drying to form solid drug nanoparticles is applied for the first time to the optimization of oral HIV therapies. A solid formulation with 70 wt% efavirenz is optimized and shown to have considerable long-term stability in the amorphous state, with lower cytotoxicity and higher in vivo oral bioavailability than conventional formulations. The results offer a reduced daily drug dose and the first oral HIV nanomedicine.
