Bisoprolol is a drug acting as a blocker of cardioselective β1 receptors. It belongs to the group of drugs known as β-blockers. It is prescribed for the treatment of heart disease, alone or in combination with other medications.

The cardiovascular diseases for which bisoprolol is prescribed are the following: arterial hypertension, coronary diseases, heart rhythm disorders, ischemic heart disease and it is also prescribed after an acute myocardial infarction. Its action is prolonged and therefore a single daily intake can be prescribed.

Bisoprolol can also be prescribed for asthmatic patients, but due to its low effect on the β2 receptors of the lung, patients must undergo a high medical control.

In addition, bisoprolol may have other indications such as anxiety and hyperthyroidism.
