Pharmacology Half Life Calculation?

Question

I'm really stuck on this question. I'm being asked to find the half life of a drug.The Vd is 50L/kg. The clearance is 0.1 L/hr/kg. The patient weighs 70 kg. Equation is:T1/2 (halflife) = 0.693 * Vd / Cl.I keep getting 0.693 * 50 / 0.1 = 346.5The right answer is 14.4 days but I can't figure it out.Thanks in advance

Answer 1

You're doing the calculation right. But you should always put units after your answer which will help you see clearly where you went wrong. According to your calculation the answer is 346.5 Hours and your answer is in Days. So, 346.5/24 = 14.4 Days.
