The elimination half-life of an antibiotic is 3 hours with an apparent volume of distribution equivalent to 20% of body weight. The usual therapeutic weight range for this antibiotic is between 5 and 15µg/ml. adverse toxicity for this drug is often observed at serum concentration greater than 20µg/ml. Calculate a dosage regimen (multiple IV doses) that will just maintain the serum drug concentration between 5 and 15µg/ml.

An adult male (73 years old, 65 kg) with diabetes mellitus is placed on hemodialysis. His residual creatinine clearance is <5mL/min. The patient is given tobramycin, an aminoglycoside antibiotic, at a dose, at a dose of 1 mg/kg by IV bolus injection. Tobramycin is 90% excreted unchanged in the urine, is less than 10% to plasma protein, and has elimination half-life 2.2 hours in patient with normal renal function. In this patient, tobramycin has an elimination t1/2 of 50hours during...
