The bioavailability of a single 100‐mg dose of danazol delivered from the commercial formulation (hard gelatin capsule) and from an experimental lipid emulsion formulation of danazol was studied in 11 healthy female volunteers in both fed and fasted states. The emulsion formulation (fasted) increased bioavailability fourfold compared with the capsule (P = .0001); the difference, however, was not significant in the fed state. Food increased the bioavailability of the capsule formulation more than threefold over fasted administration (P = .0001). In a separate study of 12 female volunteers, single doses of the emulsion formulation of danazol administered with food demonstrated essentially dose‐proportional pharmacokinetics over the dose range studied (50–200 mg). The authors conclude that factors that increase the extent of solubilization lead to significant enhancement in the bioavailability of danazol.
