Answer 40

if you take a drug, using this formula, you can tell much of it is metabolized for a certain amount of time, and how much is still in your system
in this case 6 hours later 111.57 mg of the medicine is still in your system...and working I guess...can tell you you need to take another dose...can make sure you dont take to much..
