Methotrexate is the anchor drug in the treatment of rheumatoid arthritis patients. The investigators defined initial starting doses of methotrexate as low (10 mg/week or less) or high (15 mg/week or more) based on the last reported dose of methotrexate at no later than 8 weeks of follow-up.

Then, How do you work out body surface area in square meters?

DuBois D, DuBois EF. A formula to estimate the approximate surface area if height and weight be known.

meters inches.

Body Surface Area
Formula : BSA (m2) =
Mosteller : = √ height (cm) x weight (kg) 3600
DuBois & DuBois : = 0.20247 x height (m)0.725 x weight (kg)0.425

Considering this, How is chemotherapy dosed? Chemotherapy drug doses are usually formulated in theory for mg/m2 of body surface area. Doctors don’t usually know a person’s surface area but height and weight are easy to measure so they use them. Patients vary in response to a drug, even if the patients have the same BSA and hence same dose of anti-cancer agent.
