Quizplus · Accepted Answer

Beta-blockers work by blocking the actions of the hormones epinephrine (adrenaline) and norepinephrine (noradrenaline), which are part of the body's fight-or-flight response. This results in various effects, including lowering heart rate, blood pressure, and reducing anxiety in certain situations. They do not primarily cause extreme drowsiness, are not less frequently used than benzodiazepines across all their indications, and do not block the activation of the parasympathetic nervous system.
