A 60-year-old male patient is prescribed IV gentamicin once daily for a severe infection. To optimise dosing, an adjusted body weight (AdjBW) should be used. The patient weighs 95kg and has a height of 5 feet 10 inches. The following equations are provided: Ideal body weight (IBW) Men: IBW (kg) = 50 + 2.3kg for each inch over 5 feet Women: IBW (kg) = 45.5 + 2.3kg for each inch over 5 feet Adjusted body weight (AdjBW)AdjBW (kg) = IBW + 0.3 × (actual body weight − IBW)   Gentamicin should be dosed at 5mg/kg once daily, using AdjBW. Doses should be rounded to the nearest 20mg.   What is the recommended daily dose of gentamycin in milligrams for this patient?
