Fred Flintstone • Obtain patient information -- • Age: 38 y.o. Gender: Male • Height: 5’9” Weight: 180 lbs (= 81.8 kg) • Serum creatinine: 0.9mg/dL • Perform pharmacokinetic calculations
Pharmacokinetic formulas Cockcroft and Gault equation: CrCl = [(140 - age) x IBW] / (Scr x 72) Volume of distribution (Vd) = Weight x 0.75 L/Kg Vancomycin: Kel = (0.00083 x CrCl) + 0.0044 T 1/2= 0.693 / Kel Calculate Loading dose (LD):_____mg. LD = 25mg/Kg Calculate Maintenance dose (MD):_____mg. MD = [(kel) x (Vd) x (ti) x (Cpeak desired) x (1 - e-kT)] / (1 - e-kti)
Pharmacist Note • Subjective / Objective: • 38 y/o caucasian male admitted with cellulitis, start vancomycin per pharmacy • Pertinent labs: • SCr: 0.9 mg/dL • WBC 18,000 Temp: 101.7 °F • 4/28/10 Wound cultures: pending • Assessment / Plan: • Give vancomycin loading dose 2000mg IV x1, then start vancomycin 1750mg IV every 12 hours for target concentration of 10-15mcg/ml. • Check level on 4/30/10 before morning dose
