Atenolol
Atenolol is a beta-blocker medication used to lower high blood pressure and ease chest pain. Tenormin is the listed formulation. It comes as a film-coated tablet for daily dosing.
Key points
- Also used to stabilise irregular heart rhythms, in addition to its roles in blood pressure and chest pain control.
- Works by blocking adrenaline from reaching beta-receptors on the heart, which slows the heartbeat and lightens the force of each contraction.
- Because the heart needs less oxygen once it works less forcefully, angina attacks become less frequent.
What is Atenolol?
Atenolol belongs to a class of medications called beta-blockers. These drugs slow the heart rate and reduce the force of each heartbeat. By doing so, they lower the pressure in your blood vessels.
What Atenolol is used for
Atenolol addresses Hypertension by reducing elevated blood pressure, which eases strain on the cardiovascular system. It also controls Angina Pectoris by reducing the heart’s oxygen demand, which decreases chest pain episodes. Additionally, it regulates Arrhythmia by stabilising irregular heart rhythms.
How does Atenolol work?
Atenolol works by blocking adrenaline from binding to beta-receptors on the heart. This action slows your heartbeat and reduces the force of contractions.
With the heart working less forcefully, blood pressure drops and the heart muscle needs less oxygen. This is why atenolol eases both high blood pressure and chest pain linked to angina.
