Beta blockers are readily titrated to optimal rate control in many pathologic states. [citation needed] The antiarrhythmic effects of beta blockers arise from sympathetic nervous system blockade—resulting in depression of sinus node function and atrioventricular node conduction, and prolonged atrial refractory periods.
The effect of taking beta blockers can help lower the heart rate as well as help improve the blood flow by opening up the blood vessels widely. Doctors may prescribe beta blockers as one of the medications that help reduce blood pressure , including diuretics and calcium channel blockers. [citation needed]
The combination of beta blockers and antihypertensive drugs will work on different mechanism to lower blood pressure. [17] For example, the co-administration of beta-1 blocker atenolol and ACE inhibitor lisinopril could produce a 50% larger reduction in blood pressure than using either drug alone. [18]
Since beta blockers are known to relax the cardiac muscle and constrict the smooth muscle, beta-adrenergic antagonists, including propranolol, have an additive effect with other drugs that decrease blood pressure or decrease cardiac contractility or conductivity. Clinically significant interactions particularly occur with: [35] Verapamil
Antihypertensive agents comprise multiple classes of compounds that are intended to manage hypertension (high blood pressure). Antihypertensive therapy aims to maintain a blood pressure goal of <140/90 mmHg in all patients, as well as to prevent the progression or recurrence of cardiovascular diseases (CVD) in hypertensive patients with established CVD.

When Dr. Oz sat Rachael Ray down for a blood pressure test during a segment of her show, he wasn't entirely pleased with the numbers he saw. In fact, he made her do it again -- and he called her ...
Metoprolol, sold under the brand name Lopressor among others, is a medication used to treat angina, high blood pressure and a number of conditions involving an abnormally fast heart rate. [4] It is also used to prevent further heart problems after myocardial infarction and to prevent headaches in those with migraines . [ 4 ]
Bisoprolol, sold under the brand name Zebeta among others, is a beta blocker which is selective for the beta-1 receptor [7] and used for cardiovascular diseases, [7] including tachyarrhythmias, high blood pressure, angina, and heart failure. [7] [8] It is taken by mouth. [7]
