betablockers

Cardiac rhythm medications

Beta-blockers are medications that slow the heart rate and reduce blood pressure by blocking the effects of adrenaline.

Doctors prescribe them for heart conditions, high blood pressure, anxiety, and migraines.

The name comes from their action on beta-adrenergic receptors: She takes beta-blockers for her arrhythmia.
