How does Metoprolol affect the sympathetic nervous system, and what physiological changes occur during its use for cardiovascular or stress-related conditions?
Metoprolol blocks beta-1 adrenergic receptors in the heart, reducing sympathetic stimulation. This leads to decreased heart rate, blood pressure, and cardiac workload, easing conditions like hypertension and angina.
