In medicine, metoprolol is a adrenergic beta-antagonist that is a "selective adrenergic beta-1-blocking agent with no stimulatory action. It's binding to plasma albumin is weaker than alprenolol and it may be useful in angina pectoris, hypertension, or cardiac arrhythmias." It is also used for heart failure.[1]
Metabolism
It is metabolized by cytochrome P-450 2D6 allele and so may have drug interactions[2] and inherited variations in metabolism.[3]
Dosage
For healthy adults, the starting dose is 25 to 100 mg daily in single or divided doses and the maximum dose is 400 to 450 mg/day.
Efficacy
Metoprolol can benefit patients with heart failure.[4]
