The total body clearance (CL) of amikacin is 6 L/hr and its apparent volume of distribution (V) is 20 liters. If you want to target a peak level of 20 mcg/ml at steady state and the trough level cannot fall below 5 mcg/ml what i.v. dosing regimen would you suggest?  Use the peak approach and choose the largest dosing interval from the following (every 4, 6, 8, 12, or 24 hours). The drug is administered parenterally.
