A certain drug dosage calls for 25 mg per kg per day

Question

A certain drug dosage calls for 25 mg per kg per day and is divided into two doses ( 1 every 12 hours). If a person weighs 180 pounds, how much of the drug should they get each dosage?

Answer 1

For l kg body weight, take 25 mg per day

180 lbs = 180/2.2 = 81.8 kg

This requires 81.8 × 25 mg total medicine per day = 2045.45;

dividing into two equal doses (per 12 hours) means each dose should be 1023 mg.
