Well, a 150 lbm person about 5ft6inches tall has a Body Surface Area (BSA) of about 1.78 m2 and 150lbm=68kg. So converting 200mg/kg would go 200mg/kg * 68kg / 1.78m2 = 7640mg/m2. This must be the total dose over the several days of Kevetrin infusions (10 days of 764mg/m2 or 20 days of 382mg/m2). But convert back to the proper units - 20 days of 10mg/kg dosing is a total 200mg/kg dosage. Think I did that math correctly...
