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 …
WebThe volume and clearance of the effect compartment determine the equilibration half-life. Thiopental reaches the brain quickly and is washed out rapidly because of the high blood flow to the brain which determines the high effect compartment clearance. It is the rapid washout of thiopental that leads to a short equilibration half-life of about Web1. by definition, clearance is NOT constant-half life 1. half life varies as a function of the initial concentration 2. half life is NOT constant (changes depending upon the starting concentration) how does the drug concentration decay curve for …
