How Does Aten 25 Mg Work?

Atenolol blocks the effects of adrenaline on the heart, causing the heart to beat more slowly and with less force.

This lowers blood pressure and reduces the amount of oxygen the heart needs.

Blocking adrenaline:

Atenolol, which is the chief generic element of the medicine, blocks the beta-1 adrenergic receptors.

This blocks the action of stress hormones like adrenaline and noradrenaline from attaching to these receptors and causing the heart to beat faster.

Reducing heart rate and relaxing blood vessels:

Doing this triggers a chain of events, such as reducing the rate of heartbeat. This automatically reduces the workload on the heart to pump out extra blood.

This action is crucial to get rid of chest pain and angina. Due to less blood pumped out of the heart, the arterial walls relax as well.

Reducing BP:

When the arteries relax and the blood flow inside them drops to normal levels,s it helps reduce BP levels.
