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, du… WebLouise Peach. This is referred to as a "steady state."

WebThe steady state INR is higher when the C50 is low and the INR is lower when the C50 is high. How-ever, the time to reach a new steady state INR is not affected by the C50 because it is only determined by the half-life of the clot-ting factors. The prothrombin complex of clotting factors has an average elimination half-life of about 14 hours.
