N2 - The influence of liquid intake and a lipid-rich meal on the bioavailability of a lipophilic drug was investigated. Danazol was used as the model substance. In a randomized four-way crossover study eight healthy male volunteers received four different treatments with danazol at 2-week intervals following an overnight fast (one I.V. infusion and three oral treatments). The I.V. formulation contained 50mg danazol solubilized in 40% hydroxypropyl-beta-cyclodextrin. The oral treatments were a Standard treatment, a Standard + 800 ml water treatment and a Standard + lipid-rich meal treatment. The Standard oral treatment consisted of 200 ml water and one capsule containing 100mg danazol, three 500 mg paracetamol tablets and two 500 mg sulfasalazine tablets. Paracetamol and sulfasalazine were used as markers for gastric emptying and small intestinal transit times. Intake of danazol with a lipid-rich meal or extra 800 ml water increased the bioavailability by 400 and 55%, respectively. Gastric emptying times increased in the following order: Standard
