The elimination half-life of a drug is the time in which the concentration of the drug in the plasma falls to one half of its original amount. The elimination half-life describes a drug's rate of disappearance from the body, whether by metabolism, excretion, or a combination of both. The...

For a given reaction the half-life, t1/2, of a reactant is the time required for its concentration to reach a value that is the arithmetic mean of its initial and final (equilibrium) value.
The Half-Life of a chemical reaction can be defined as the time taken for the concentration of a given reactant to reach 50% of its initial concentration.
