What is the role of bisoprolol (beta blocker) as an antihypertensive agent?

From the Guidelines

Bisoprolol has a significant role as an antihypertensive agent, particularly in patients with heart failure, post-myocardial infarction, or angina, as it reduces morbidity and mortality, as recommended by the 2013 ACCF/AHA guideline for the management of heart failure 1.

Key Points

• Bisoprolol is a cardioselective beta-1 receptor antagonist that lowers blood pressure by reducing heart rate, cardiac output, and renin release from the kidneys.
• The typical starting dose is 2.5-5 mg once daily, which can be titrated up to a maximum of 20 mg daily based on blood pressure response.
• Bisoprolol is beneficial for hypertensive patients with concurrent conditions like angina, heart failure, or post-myocardial infarction, as it reduces the risk of cardiovascular morbidity and mortality, as stated in the 2017 ACC/AHA/AAPA/ABC/ACPM/AGS/APhA/ASH/ASPC/NMA/PCNA guideline for the prevention, detection, evaluation, and management of high blood pressure in adults 1.
• Its cardioselectivity means it has fewer respiratory side effects compared to non-selective beta-blockers, making it safer for patients with mild to moderate asthma or COPD.
• Common side effects include fatigue, dizziness, and bradycardia, and patients should not abruptly discontinue bisoprolol to avoid rebound hypertension.
• Blood pressure and heart rate monitoring is essential when initiating therapy or adjusting doses to ensure optimal response and minimize adverse effects, as recommended by the 2013 ESH/ESC guidelines for the management of arterial hypertension 1.

Considerations

• Beta-blockers, including bisoprolol, may be inferior to some other drug classes for certain outcomes, such as stroke prevention, but are effective in preventing coronary outcomes and reducing cardiovascular events in patients with a recent myocardial infarction or heart failure, as reported in the European guidelines on cardiovascular disease prevention in clinical practice (version 2012) 1.
• Vasodilating beta-blockers, such as carvedilol and nebivolol, may have a more favorable profile than traditional beta-blockers, with reduced central pulse pressure and aortic stiffness, and less effect on insulin sensitivity.
• The choice of antihypertensive agent should be individualized based on patient characteristics, comorbidities, and concomitant medications, with consideration of the potential benefits and risks of each agent.

From the FDA Drug Label

Bisoprolol fumarate is indicated in the management of hypertension. It may be used alone or in combination with other antihypertensive agents.

The role of bisoprolol as an antihypertensive agent is to manage hypertension. It can be used alone or in combination with other antihypertensive agents. The mechanism of action of its antihypertensive effects has not been completely established, but factors that may be involved include:

• Decreased cardiac output
• Inhibition of renin release by the kidneys
• Diminution of tonic sympathetic outflow from the vasomotor centers in the brain 2.

From the Research

Role of Bisoprolol as an Antihypertensive Agent

Bisoprolol is a cardioselective beta-blocker that plays a significant role in the treatment of hypertension. The key aspects of its role include:

• Reduction of blood pressure: Bisoprolol has been shown to effectively lower systolic and diastolic blood pressure in patients with hypertension 3.
• Improvement of cardiac function: Studies have demonstrated that bisoprolol can improve cardiac function in patients with heart failure, which is often comorbid with hypertension 4, 5.
• Reduction of resting heart rate: Bisoprolol has been found to reduce resting heart rate, which is a strong predictor of total mortality and hospitalization due to heart failure in hypertension patients 6.

Efficacy and Safety of Bisoprolol

The efficacy and safety of bisoprolol in the treatment of hypertension have been established through various studies. Some key findings include:

• Bisoprolol has been shown to be effective in reducing blood pressure and improving cardiac function in patients with hypertension and heart failure 3, 4.
• The drug has been found to be safe and well-tolerated, with no significant increase in adverse reactions compared to other beta-blockers 4, 7.
• Bisoprolol has been compared to other beta-blockers, such as carvedilol and metoprolol succinate, and has been found to have similar effects on mortality amongst patients with chronic heart failure 7.

Clinical Applications of Bisoprolol

Bisoprolol has several clinical applications, including:

• Treatment of hypertension: Bisoprolol is commonly used to treat hypertension, either as a monotherapy or in combination with other antihypertensive agents 3.
• Treatment of heart failure: Bisoprolol is also used to treat heart failure, particularly in patients with reduced left ventricular ejection fraction 4, 5.
• Perioperative correction of hypertension: Bisoprolol may be used to correct hypertension in the perioperative period, particularly in patients undergoing surgery 3.
