A 7-year-old child will be receiving amoxicillin (Amoxil) 80 mg/kg/day in 2 divided doses. The child weighs 55 pounds. The medication, once reconstituted, is available as an oral suspension of 50 mg/mL. How many milliliters will the child receive per dose?
Convert pounds to kilograms: 55 pounds = 25 kg
25 kg ´ 80 mg/kg/day = 2000 mg/day.
To get the amount per dose, divide 2000 by 2, which equals 1000 mg/dose.
To calculate the milliliters:
50 mg : 1 mL :: 1000 mg : x mL
(50 ´ x) = (1 ´ 1000); 50x = 1000; x = 20; give 20 mL per dose
