The number of 200-mg quinidine sulfate tablets that will be needed for this regimen is 15 tablets.
Since the patient is given an initial dose of 200 mg of quinidine sulfate, followed later in the day by two 200-mg doses. And since the daily dosage is then increased by 200 mg/day until a daily dose of 3000 mg is reached.
His daily dosage is thus 3000 mg per day.
Since we have 200-mg quinidine sulfate tablets, we require the number of 200-mg quinidine sulfate tablets that would give a dose of 3000 mg.
so, number of tablets required, n = dose/dose per tablet.
The dose = 3000 mg and the dose per tablet = 200 mg
n = dose/dose per tablet.
n = 3000 mg/200 mg
n = 15 tablets
So, the number of 200-mg quinidine sulfate tablets that will be needed for this regimen is 15 tablets.
