The dose of beclomethasone inhalant is 200mcg twice a day. The commercial inhaler delivers 50mcg per inhalation and contains 200 inhalations. How many inhalers should be dispensed to a patient if a 60-day supply is prescribed?

Answer 1

200 mcg 2x daily = 400 mcg/day.
The inhaler is good for 50 mcg/squirt so that gives it 400/50 ps (per squirt) = 4 spd (squirts per day). One inhaler, then, is good for 200 squirts/4 spd = 50 days. You can work out the remainder. Check my arithmetic and thinking.
