If the usual adult dose of a drug is 120 mg, what would be the dose based on BSA for a person measuring 6 feet tall and weight 200 lb? (2.2lb/kg; 2.54 cm/in)
Normal Adult dose :120mg
Dose for a person measuring
Height=6 feet=72inch=182.8cm(one feet=12 inch)
Weight=200lb=90.9kg
BSA(body surface area)
m^2=√ht(cm)*wt(kg)/3600
=√182.8*90.9/3600
=√4.61
=2.14meter square
Dosage required=2.14*120/1.7m square
=151mg
Answer The dose for the person of height 6 feet and 200 pounds body weight is 151mg
Note:√=square root

For many drugs, it is important to adjust the dose for individual patients. A patient's body weight or body surface area (BSA) is sometimes used for estimating drug dosages for children and for estimating the starting dosage for chemotherapy for cancer patients. BSA is difficult to measure directly, but it may be calculated by the following formula based on height and weight. BSA = 71.84W0.425H0.725, where BSA is measured in square centimeters, W is weight in kilograms, and H is...
