 In a study in which a single 50 µg/kg subcutaneous dose was administered to eighteen healthy men, the peak serum concentration (Cmax) of 17.4 ± 5.4 ng/mL was reached at 3.2 ± 2.4 h (Tmax) following dosing.The terminal half-life was 6.9 ± 1.7 h. In a second study in which single 75 µg/kg subcutaneous and intravenous doses were administered to twenty-four healthy subjects, the pharmacokinetic profiles were similar between men and women.The absolute bioavailability of Neumega was >80%.
