Web23 Mar 2024 · One format involves calculating a mass amount of the original isotope. Using the equation below, we can determine how much of the original isotope remains after a certain interval of time. how much mass remains = 1 2n(original mass) n is the number of half-lives. Example 5.7.1. Web24 Feb 2024 · t½ = 0.693 × (Vd /CL) Where, Vd = Volume of distribution and CL = Clearance. 5. t max is peak plasma time. On the other hand, t 1/2 is the elimination half-life. 6. t max (peak plasma time) is a rough marker of the average rate of drug absorption. On the other hand, t 1/2 is an indicator of how fast a drug is eliminated from the body.
