What Is the Role of Body Surface Area (BSA) in Dosage Calculations?

Certain medications, especially chemotherapy agents, require dosing based on Body Surface Area (BSA). The BSA can be calculated using the Mosteller formula:
\[ \text{BSA (m}^2\text{)} = \sqrt{ \left( \frac{\text{Height (cm)} \times \text{Weight (kg)}}{3600} \right) } \]
For instance, if a patient’s height is 170 cm and weight is 70 kg, the BSA would be:
\[ \sqrt{ \left( \frac{170 \times 70}{3600} \right) } \approx 1.84 \text{ m}^2 \]
