gonyyong I think the distribution half-life and elimination half-life was saying that by the time you checked, it had fully distributed (10 half-lifes) and had not been cleared yet (super long half-life) +14

soph 1000ug= 1mg and 1g=1000000ug so then 4ug/ml * 1g/ 1000000ug= 0.000004 g/ml 0.000004g/ml * 1000ml/L= 0.004 g/L 80mg*1g/1000mg= 0.08 g vd= 0.08g/ 0.04g/l =20L +4

tiredofstudying Or, like a normal human, convert 4ug/mL into mg/L ... which is 4 mg/L. 80mg/4mg/L is 20L. +17

skinnynomore this kid has chronic pyelonephritis due to recurrent UTIs (VUR/hydronephrosis is a risk factor). And -itis = inflammation. That was my take on it. +3
