What are cardioselective beta blockers?
Beta blockers, also called beta-adrenergic blocking substances, B-blockers or beta antagonists, are medicines used for different cardiovascular conditions. Cardioselective beta blockers differ from non -selective beta blockers when targeting beta receptors in the cells of the cardiovascular system. It is assumed that at higher doses, cardi -selective beta blockers are not absolutely selective and can also bind to receptors in other areas of the body. Norepinephrine and adrenaline in the receptor activation stops by linking beta-entenaceptors. Some beta blockers provide some partial activation of the receptors, while others don't. Esmolol, nebivolol and bisoprolol are also cardioselective beta blockers. These drugs are primarily used to treat hypertension, but are also prescribed for cardiac arrhythmias, prolapse of mitral valves, Anginaa other conditions. Clinical studies have shown that drugs are beneficial to patients with congestive heart failure. Cardioselective blockers betaThey slow down the heart rate and act by increasing the ability of blood to bear oxygen, which is useful in the treatment of this disease.
by reducing heart rate and reducing heart rate, beta blockers alleviate hypertension. They keep the effects of stress hormonal epinephrine, also known as adrenaline, which increases heart rate and production. Some beta blockers are also vasodilators that reduce blood pressure by increasing the average of the arteries, allowing blood to flow through less force. They can also work in other ways, including reducing the kidney enzyme that helps regulate blood pressure.
The commonly reported side effects of beta blockers include cold hands and legs and a slow heart rhythm. Reduced heart rate can cause fatigue in Some patients. Betta blockers can also cause ankle swelling and joint pain. Some beta blockers have higher solubility in lipids and mayRelify the barrier of the bleed-stroke easier than those that are soluble in the water. This can cause side effects of the nervous system, including nightmares and other symptoms.
Concerns about the use of cardi -sectic beta blockers in patients with chronic obstructive pulmonary disease (COPD) and other mild to medium respiratory diseases have proven to be unfounded. Research shows that cardioselective beta blockers do not cause bronchial narrowing and convulsions in these patients. It is believed that patients with cardiovascular states in addition to lung problems could benefit from using B-blockers. Although in high doses, cardioselective beta blockers are not exclusively selective, research has shown that there is no negative effect on COPD symptoms with short -term use of these beta blockers.P>
