How Does Bisoprolol Lower Blood Pressure?

Bisoprolol blocks beta1-adrenergic receptors, reducing sympathetic stimulation of the heart. This slows heart rate and lowers cardiac output. It also reduces renin release from the kidneys, which affects the renin-angiotensin system involved in blood pressure regulation. Its beta1 selectivity is strongest at lower doses and becomes less selective as the dose rises.

Who Is Treated With Bisoprolol?

Bisoprolol fumarate tablets are approved for management of hypertension in adults. They can be used alone or with other blood pressure medicines. Pediatric use has not been established under current U.S. tablet labeling. Kidney or liver impairment affects starting dose selection and calls for cautious dose increases.

How Are Bisoprolol Tablets Dosed?

The usual starting dose is 5 mg once daily. Some patients start at 2.5 mg. When 5 mg does not lower blood pressure adequately, the dose can increase to 10 mg and then to 20 mg once daily. Patients with marked kidney dysfunction or liver impairment commonly start at 2.5 mg once daily.

What Safety Problems Need Attention With Bisoprolol?

Bisoprolol can cause slow heart rate, low blood pressure, dizziness, fatigue, and worsening heart failure in susceptible patients. Abrupt withdrawal can worsen angina or trigger myocardial infarction in people with coronary artery disease. Cardiogenic shock, overt heart failure, advanced heart block, and marked sinus bradycardia are contraindications under current labeling.
