Concor® COR 2.5 mg contains Bisoprolol Fumarate, a Cardioselective beta-blocker primarily used in the treatment of stable chronic heart failure. It works by selectively blocking beta-1 adrenergic receptors in the heart, reducing the heart rate and the workload on the heart, thereby improving cardiac function. This helps alleviate symptoms associated with heart failure, such as shortness of breath and fatigue. The 30 film-coated tablets are taken as part of a long-term treatment regimen to manage heart failure and prevent its progression. Bisoprolol is typically prescribed alongside other therapies for heart failure to optimize outcomes.
