Practice exercise (made-up values, not clinical guidance). A patient starts regular doses of gentamicin, which has a half-life of 2 h. Using the rule that steady state is reached after about five half-lives, after how many hours tss is steady state reached?
Practice exercise (made-up values, not clinical guidance). A patient starts regular doses of vancomycin, which has a half-life of 10 h. Using the rule that steady state is reached after about five half-lives, after how many hours tss is steady state reached?
Practice exercise (made-up values, not clinical guidance). A patient receives an IV bolus of 100 mg of tobramycin. The level back-extrapolated to time zero is 7 mg/L and the half-life is 2.5 h. Find the clearance CL in L/h.
Practice exercise (made-up values, not clinical guidance). A 68 kg patient receives a theophylline infusion. The clearance is 0.04 L/kg/h. What infusion rate R in mg/h gives a steady-state level of 10 mg/L?
Practice exercise (made-up values, not clinical guidance). An 85 kg patient has a digoxin level of 0.4 mcg/L; the target is 1 mcg/L. The volume of distribution is 7 L/kg and the tablets have F = 0.7. What extra loading dose LD raises the level to the target?
Practice exercise (made-up values, not clinical guidance). A 78 kg patient takes oral theophylline (F = 1) every 12 h. The clearance is 0.04 L/kg/h. Each dose is 400 mg of theophylline. Find the average steady-state level Css,avg.
