Background:
Metoprolol-d6is intended for use as an internal standard for the quantification of metoprolol by GC- or LC-MS. Metoprolol is a potent and selective β1-adrenergic receptor (β1-AR) antagonist (Ki= 47 nM).1It is selective for β1- over β2- and β3-ARs (Kis = 2.96 and 10.1 μM, respectively).In vivo, metoprolol (2.5 mg/kg per hour) reduces aortic atherosclerotic plaque area, serum levels of TNF-α and CXCL1, and plaque macrophage content in anApoE-/-mouse model of atherosclerosis.2Metoprolol (1 mg/kg per day) reduces biventricular cavity expansion and myocardial necrosis in a mouse model of encephalomyocarditis-induced congestive heart failure when administered in combination with captopril .3Formulations containing metoprolol have been used in the treatment of high blood pressure and heart failure.
