Metoprolol Tartrate

Metoprolol Tartrate (CAS No.: 56392-17-7) is a selective β1-adrenergic receptor blocker, mainly used to treat cardiovascular diseases such as hypertension, angina, and arrhythmias. By inhibiting cardiac β1 receptors, it reduces heart rate and myocardial contractility, thereby decreasing myocardial oxygen consumption to achieve therapeutic effects. In vitro studies show that Metoprolol Tartrate inhibits β1 receptors in the nanomolar to micromolar range, with specific activity levels depending on experimental conditions and cell types. In cell models, it is commonly used to evaluate β1 receptor-mediated signaling pathways and the regulation of cardiomyocyte function. In animal models, Metoprolol Tartrate has been used to study its effects on cardiovascular function, and the doses or concentrations used in experiments typically depend on the experimental design and research objectives.
