If a drug recommend 100mg/m2 per dose, what is the dosage (per dose) for an infant that have a BSA of 0.9?
Answers:
The dose is 90mg.
See below for calculations!
The units attached to BSA are meters squared.
So, is a BSA is 0.9 that means that the body surface nouns is 0.9 meters squared.
So...
A drug dosed at 100mg/meters squared is (100mg for EACH square meter):
100 mg/1 meter squared = X mg/0.9 meters squared
Solve for X using cross multiplication.
You get 90mg as the dose. Source(s): Pharmacy technician for 8 years, compund chemotherapy (uses BSA dose calculations), TA at a college of pharmacy that teaches this material
