Absorption: Well absorbed after oral administration. Distribution: Crosses the blood-brain barrier, crosses the placenta; small amounts enter breast milk. Metabolism and Excretion: Mostly metabolized by the liver (primarily by CYP2D6; the CYP2D6 enzyme system exhibits genetic polymorphism); ~7% of population may be poor metabolizers and may have significantly ↑ metoprolol concentrations and an ↑ risk of adverse effects.

Due to the high penetration across the blood-brain barrier , lipophilic beta blockers such as propranolol and metoprolol are more likely than other less lipophilic beta blockers to cause sleep disturbances such as insomnia and vivid dreams and nightmares. Serious side effects that are advised to be reported immediately include symptoms of bradycardia (resting heart rate slower than 60 beats per minute), persistent symptoms of dizziness, fainting and unusual fatigue, bluish discoloration of the fingers and toes, numbness/tingling/swelling of the hands or feet, sexual dysfunction , erectile dysfunction , hair loss, mental/mood changes, depression, breathing difficulty, cough, dyslipidemia and increased thirst.
