WebJun 30, 2015 · Half-life (t½) is the time required to change the amount of a drug in the body by one-half during elimination. The two main factors which affect drug half-life are … The half-life of a drug is an estimate of the time it takes for the concentration or amount in the body of that drug to be reduced by exactly one-half (50%). The symbol for half-life is t½. For example, if 100mg of a drug with a half-life of 60 minutes is taken, the following is estimated: 1. 60 minutes after … See more * Note that half-life varies depending on the source used.
