Total tried: Correct: Wrong:
The adult dose of a drug is 1200 mg every 8 hours. For an elderly patient with impaired renal function, the dose is reduced to 600 mg every 6 hours. Calculate the percentage reduction in the daily dose.

lb equals 33.33% kg
Adult total dose = `(1200 mg) / (8 hr) × (24 hr) / (1 day)` = 3600 `(mg) / (day)`
Reduced total dose = `(600 mg) / (6 hr) × (24 hr) / (1 day)` = 2400 `(mg) / (day)`
Amount reduced = 3600 mg – 2400 mg = 1200 mg
The percentage reduction in the daily dose
= `(1200 mg)/(3600 mg) × 100 %` = 33.33 % Ans.
Reduced total dose = `(600 mg) / (6 hr) × (24 hr) / (1 day)` = 2400 `(mg) / (day)`
Amount reduced = 3600 mg – 2400 mg = 1200 mg
The percentage reduction in the daily dose
= `(1200 mg)/(3600 mg) × 100 %` = 33.33 % Ans.
