Bisoprolol fumarate is a highly selective beta-blocker, and this type of drug is used more often in clinical settings with relatively few side effects. Possible adverse reactions that may occur during the administration of the drug include headache, dizziness, fatigue, sleep disorders, and in some people, bradycardia may occur after taking bisoprolol because the dose chosen is not very appropriate. In addition, some patients may induce airway spasm after taking this drug for people who have bronchial asthma or chronic obstructive pulmonary disease themselves. Studies have also confirmed that taking this drug may affect glucose and lipid metabolism, so patients with diabetes should also be careful about taking this drug. In clinical practice, this drug is mainly used for the treatment of hypertension, angina pectoris, and heart failure.
