Metabolism The pharmacokinetic profile of metoprolol (Lopressor) is similar to that of propranolol. Metoprolol is readily and rapidly absorbed after oral administration and is subject to a significant amount of first-pass metabolism by the liver. Curiously, the duration of metoprolol’s action is longer than one would predict from its plasma half-life, which ranges from 0.5 to 2.5 hours. The degree of binding of metoprolol to plasma proteins is modest (10%). The extensive distribution of metoprolol to the lungs and kidney is typical of a moderately lipophilic drug. Metoprolol undergoes considerable metabolism;only 3 to 10% of an administered dose is recovered as unchanged drug.The metabolites are essentially inactive as -receptor blocking agents and are eliminated primarily by renal excretion. Small amounts of the drug are present in the feces.
