Explain how the effect of cardioselective beta-blocker drugs differs from that of regular beta-blocker drugs. What type of patient are cardioselective beta-blocker drugs specifically used to treat?
What will be an ideal response?
Answer: Regular beta-blocker drugs slow the heart rate and cause the blood vessels to dilate to treat hypertension. But these drugs also cause the bronchioles to constrict. Cardioselective beta-blocker drugs are more selective in their effect and only slightly block beta2 receptors in the bronchioles. Patients who have hypertension and lung disease are specifically given cardioselective beta-blocker drugs.
