What Is Bisoprolol?

Bisoprolol is a drug that belongs to a group called beta-blockers. These medicines affect the blood flow through arteries and veins by blocking the action of epinephrine on the heart and blood vessels. It is used to treat hypertension and heart failure, as it lowers blood pressure and prevents heart attacks, stroke, and kidney diseases. It comes as a tablet, and only available on prescription.

Bisoprolol is well-tolerated because it is a cardioselective β1-adrenergic blocking agent and is a useful alternative to non-selective β-blocker drugs like Carvedilol and Labetalol. It can be used alone or in combination with other drugs and is useful in patients with chronic obstructive pulmonary disease (COPD).

What Is Bisoprolol Used For?

It is used to treat hypertension and heart failure. Lowering blood pressure prevents heart attacks, strokes, and kidney problems. Apart from high blood pressure, Bisoprolol is also used to treat atrial fibrillation and prevent chest pain due to angina.

How Does Bisoprolol Work?

Bisoprolol works by enhancing the heart’s ability to relax. It makes the heart beat slower and less forcefully. This relaxes the arteries and veins and reduces blood pressure and relieves irregular heart rhythms.

Bisoprolol blocks the adrenalin stimulation of beta receptors found in the heart muscle cells and heart conduction tissue. Usually, adrenalin and noradrenalin stimulation by beta receptors result in contraction of heart muscles and blood vessels, which increases the heart rate and blood pressure. Bisoprolol blocks this action, which makes the heart to contract slowly and lowers heart rate and blood pressure.


What Is the Dosage of Bisoprolol?

Bisoprolol tablets are available in 5 mg (milligram) and 10 mg strengths. Always take any tablet as prescribed by the doctor. Do not alter the dosage, unless suggested by the doctor. The dosage is:

  • For hypertension - 2.5 to 5 mg orally once a day, can increase up to 10 or 20 mg per day if necessary.

  • For heart failure - 1.25 mg orally once a day, can increase gradually not more than 10 mg per day.

For people suffering from asthma or any respiratory problems, kidney and liver problems, the doctor will prescribe 2.5 mg of Bisoprolol and then increase the dose gradually if needed.
