The usual dose of a novel drug for adult over 25 y of age is 6 to 56 mg/kg of body weight. What would be the usual range for a adult weighting 170 lb?


Click on the button below to see the answer and explanations

lb equals 460 mg - 4300 mg kg


  • Simple DA method for 6 mg drug
`(6 \quad mg)/(1\quad kg) × 170 \quad lb × (0.454\quad kg)/(1\quad lb)` = 463.08 mg


  • Simple DA method for 56 mg drug
`(56 \quad mg)/(1\quad kg) × 170 \quad lb × (0.454\quad kg)/(1\quad lb)` = 4322.08 mg


Therefore, range is from 463.08 mg to 4322.08 mg actually, literatures round these numbers and express as 460 mg to 4300 mg
