lb equals 400.00mg kg
Adult total dose = `(500 mg) / (6 hr) × (24 hr) / (1 day)` = 2000 `(mg) / (day)`
Reduced total dose = `(400 mg) / (6 hr) × (24 hr) / (1 day)` = 1600 `(mg) / (day)`
Amount reduced = 2000 mg – 1600 mg = 400 mg
Ans.
Reduced total dose = `(400 mg) / (6 hr) × (24 hr) / (1 day)` = 1600 `(mg) / (day)`
Amount reduced = 2000 mg – 1600 mg = 400 mg
Ans.
