A biological half-life or elimination half-life is the time it takes for a substance (drug, radioactive nuclide, or other) to lose one-half of its pharmacologic, physiologic, or radiological activity. In a medical context, the half-life may also describe the time that it takes for the concentration of a substance in blood plasma to reach one-half of its steady-state value (the "plasma half-life"). The relationship between the biological and plasma half-lives of a substance can be complex, d… WebThe two major factors that affect drug half-life include: Kinetics: Two types of elimination kinetics may affect the half-life: First-order kinetics: The clearance rate directly depends on the initial concentration. The higher the amount, the higher the clearance. Most drugs follow first-order kinetics.
