2. Oseltamivir (Tamiflu®) 150 mg + Ethanol. In this phase, subjects will drink the same amount of orange juice over 15 minutes that will now have ethanol (alcohol) added. The amount of ethanol that will be added is calculated to achieve a blood alcohol concentration of 0.08 g/dl, which is considered to be legally intoxicated. Fifteen minutes after drinking the orange juice + ethanol, subjects will receive two (2) 75 mg capsules of oseltamivir with 5 ounces of water. Blood samples will be collected at the same times as above. An additional blood sample (1 teaspoonful) for determining the blood alcohol concentration will be collected 30 minutes after drinking the orange juice + ethanol.
