1. What Concor Cor 2.5 is and what it is used for

The active substance in Concor Cor 2.5 is bisoprolol fumarate. Bisoprolol belongs to a group of medicines called beta-blockers. These medicines affect the body's response to certain nerve impulses, particularly in the heart. As a result, bisoprolol slows down heart activity and thereby improves the heart's efficiency in pumping blood throughout the body.
Heart failure occurs when the heart muscle is weak and unable to pump enough blood to meet the body’s needs.
Concor Cor 2.5 is used in the treatment of stable, chronic heart failure.

2. Important information before taking Concor Cor 2.5

When not to take Concor Cor 2.5

  • you have untreated phaeochromocytoma, a rare tumour of the adrenal gland,
  • you have metabolic acidosis, a condition in which blood pH is abnormal,
  • you have acute heart failure,
  • your heart failure worsens and intravenous administration of drugs that increase heart contractility becomes necessary,
  • you have symptoms of a slow heartbeat,
  • you have symptoms of low blood pressure,
  • you have certain heart conditions causing very slow or irregular heartbeat (second- or third-degree atrioventricular block, sinoatrial block, sick sinus syndrome) in the absence of a pacemaker,
