For a 100 kg patient, what is the daily dose of ethambutol at 25 mg/kg/day?

Explanation:
Dosing by weight is done by multiplying the patient’s weight by the dose per kilogram per day. For a 100 kg patient receiving 25 mg per kg per day, you multiply 100 × 25, which equals 2500 mg per day. So the daily dose would be 2500 mg. In practice, ethambutol is given in a weight-based range (often 15–25 mg/kg/day), and clinicians round to available tablet strengths, but the calculated daily total at the specified 25 mg/kg/day is 2500 mg.
