WebJun 30, 2015 · Half-life (t½) is the time required to change the amount of a drug in the body by one-half during elimination. The two main factors which affect drug half-life are volume of distribution and clearance; the formula for half-life is (t½ = 0.693 × Vd /CL). The 0.693 factor is in fact the logarithm of 2, which represents the fact that drug clearance typically …
