Total tried: Correct: Wrong:
If the adult dose of a drug is 450 mg, calculate the approximate dose for a child with a BSA of 0.71 m2

lb equals 319.50 mg kg
- Here Patient's BSA = 0.71 `m^2`
- Adult dose for patient = 450 mg
We know that,
Patient's dose (mg) = `(Patient's \quad BSA \quad m^2)/(1.73 \quad m^2)` × Drug dose (mg)
Patient's Dose = `(0.71 \quad m^2)/(1.73 \quad m^2)` × 450 mg = 319.5 mg Ans.
