Question

A patient weighing 66 lbs. is prescribed Augmentin 30 mg/kg/day by mouth in divided doses every 8 hours. How many mg of the medication should the patient receive for each dose?

Answer 1

Answer:

A patient who weighs 66 pounds, about 30 kg, should receive a 30 mg dose of Augmentin, according to the recommended dose.

Explanation:

Augmentin is an antibiotic composed of amoxicillin and clavulanic acid, used in the treatment of respiratory infections.

If a patient is prescribed Augmentin, at a rate of 30 mg/kg/day orally every 8 hours:

• Recommended dose: 30 mg/kg/day
• Interval between doses: 8 hours (TID)
• Patient weight: 66 pounds = 29.94 Kg ≈ 30 Kg

The patient's weight must be converted from lbs to Kg, which is done through the equivalence of measurements, where 1 lb = 0.453592 Kg.

Weight (Kg) = 66 X 0.453592 = 29.937072 ≈ 30 Kg

To calculate the dose of the drug, the dose per day should be multiplied by the patient's weight, and then divided by the three recommended doses (c/8h):

• Augmentin dose = (30 mg X 30 mg/day) / 3
• Augmentin Dose = 900 mg/3
• Augmentin dose = 300 mg

The patient should receive 300 mg per dose of Augmentin during his treatment.
