WebMar 18, 2024 · Half-life ( t 1/2) is the time required for the plasma concentration to reduce the amount of drug in the body by 50%. Half-life is expressed in minutes or hours. Thus, after two half-lifes, 25% of the drug is left; after three, 12.5%; and after 4 half-lives, 6.25%. The half-life determines the length of the drug’s effect.
