Question

Quizplus · Accepted Answer

Beta-blockers work by blocking the effects of adrenaline on the heart, which can slow down the heart rate and lower blood pressure. This makes them a common choice for treating cardiac conditions such as hypertension, heart failure, and angina. Norepinephrine and epinephrine actually increase heart rate and are not used to reduce it. Anticholinesterases increase the activity of the parasympathetic nervous system, which can also increase heart rate.
