Celectol, known generically as celiprolol, is a medication primarily used in the management of high blood pressure (hypertension) and to prevent the occurrence of chest pain from angina. It belongs to a class of drugs known as beta blockers, which work by blocking the action of certain natural substances in your body, such as epinephrine, on the heart and blood vessels. This action helps to lower heart rate, blood pressure, and strain on the heart. Celiprolol is distinct from other beta blockers as it is a selective beta-1 adrenergic receptor antagonist with partial beta-2 agonist activity, which means it specifically targets the heart, thereby minimizing effects on the lungs and other parts of the body. This makes Celectol a suitable option for patients with mild to moderate asthma or chronic obstructive pulmonary disease (COPD) in need of a beta blocker. However, like all medications, it should be used under the guidance of a healthcare provider, who can evaluate its benefits against potential risks and side effects.
