1. It is a non-selective competitive inhibitor of adrenergic β-receptor blocker, blocking β1 and β2 receptors on the heart, antagonizing the effects of sympathetic nerve excitation and catecholamines, reducing the contractile force and contractile speed of the heart, while inhibiting the contraction of vascular smooth muscle, reducing myocardial oxygen consumption, and restoring the oxygen supply and demand relationship of ischemic myocardium to a low level of balance, and can be used to treat angina pectoris. 2. It inhibits the adrenergic excitement of cardiac pacemaker potentials and is used to treat arrhythmias. 3. It can be used to treat hypertension by blocking central and adrenergic neurons, inhibiting renin release and reducing cardiac output. 4. It competitively antagonizes the effects of isoproterenol and norepinephrine, blocks β2 receptors, and reduces the effects of plasma-related substances.
