DurgBank states the following information regarding metoprolol half-life:

Mean effective half-life: 3 to 7 hours

Administered orally, metoprolol has a bioavailability of about 50 percent; intravenous (IV) administration of metoprolol has a bioavailability of 100 percent. This means the body can absorb about half of the metoprolol available in a pill and all of the medication from an IV. The liver breaks down metoprolol, and the body eliminates the drug through urine. The drug does not accumulate in the body.
