How do half lives work
WebThe elimination half-life is the amount of time required for 50% of the drug to be removed from the blood during the terminal elimination phase. This can be determined graphically from a linear plot of time versus log concentration ( Fig. 50.4 ), or it can be calculated using the equation below: Figure 50.4.
