Assume that Ali (same patient in question 1) was prescribed vancomycin 1000 mg every 36 hours. After few days, Steady-state vancomycin concentrations were obtained before and after the fourth dose, and the peak concentration (obtained ½ hour after a 1- hour infusion of vancomycin) was 34 µg/mL while the trough concentration (obtained immediately before dosage administration) was 2.5 pg/mL. Compute a revised vancomycin dose for this patient to provide a steady-state peak concentration of 48 ug/mL and a steady- state trough concentration of 17 pg/mL. a. Estimate new rate constant (Ke) and half-life (t1/2) b. Estimate volume of distribution (Vd) using this equation Cmaxss + Cminss C. Calculate the new dose interval d. Calculate the new dose
