Elimination Half Life

Definition:

The elimination half life of a medication refers to the time necessary for the drug to be reduced to half of its original level in the body through various bodily processes. The longer the half life, the longer it will take the drug to be purged from the body. This may be especially important if a medication needs to be discontinued due to side effects or for certain changes in medication regimens.
