How much drug excreted during the 2nd "half-life" period?
A doctor has provided 1 answer
See below: Half-life means how long it takes for half of the remaining substance to degrade or be cleared from the system. So if you have 1g, then during the 1st half-life, 500 mg is gone. You're left with 500 mg. After the 2nd half-life, 250 mg is gone, leaving 250 mg, and so on.
