The mechanism of carvedilol in heart failure is due to its inhibition of receptors in the adrenergic nervous system, which releases noradrenaline to the body, including the heart. [13] Noradrenaline is a hormone that causes the heart to beat faster and work harder. [13]
Alpha blockers work by blocking the effect of nerves in the sympathetic nervous system. This is done by binding to the alpha receptors in smooth muscle or blood vessels. [37] α-blockers can bind both reversibly and irreversibly. [2] There are several α receptors throughout the body where these drugs can bind.
[14] [15] [16] Bisoprolol, carvedilol, and sustained-release metoprolol are specifically indicated as adjuncts to standard ACE inhibitor and diuretic therapy in congestive heart failure, although at doses typically much lower than those indicated for other conditions. Beta blockers are only indicated in cases of compensated, stable congestive ...

Women are often concerned about the safety of antihypertensives and as a result, many do not take their treatment as prescribed. Shared decision-making aids have been shown to reduce women's uncertainty about taking antihypertensives and increase the number of women taking them as prescribed. [70] [71]

Unlike beta blockers, calcium channel blockers do not decrease the responsiveness of the heart to input from the sympathetic nervous system. Since moment-to-moment blood pressure regulation is carried out by the sympathetic nervous system (via the baroreceptor reflex ), calcium channel blockers allow blood pressure to be maintained more ...
