The bioavailability of high surface area danazol formulations was evaluated in a mouse model to determine what effect high supersaturation, as measured in vitro, has on the absorption of a poorly water soluble drug. Danazol, a biopharmaceut…

High-potency danazol particles with high dissolution rates were produced by evaporative precipitation into aqueous solution (EPAS). Aqueous suspensions formed by EPAS were centrifuged to remove the nonadsorbed surfactant. The resulting surf…

The objective of this study was to produce, by spray freezing into liquid (SFL) technology, high-potency, high glass transition temperature (Tg) danazol/polymer powders that remain amorphous and exhibit high dissolution rates after 6 months…

The objective of this study was to investigate the use of organic solvents in the spray freezing into liquid (SFL) particle engineering process to make rapid dissolving high potency danazol powders and to examine their particle size, surfac…

PurposeTo develop and demonstrate a novel particle engineering technology, spray freezing into liquid (SFL), to enhance the dissolution rates of poorly water-soluble active pharmaceutical ingredients (APIs).MethodsModel APIs, danazol or car…
