Non-selective beta blockers produce which combination of effects?

Explanation:
Non-selective beta blockers block both beta-1 receptors in the heart and beta-2 receptors in the airways. Blocking beta-1 reduces heart rate and contractility, lowering cardiac output and often decreasing blood pressure. Blocking beta-2 removes the usual bronchodilatory effect, leading to bronchoconstriction. Taken together, the expected effects are a slower heart rate, lower blood pressure, and narrowed airways. They would not cause an increased heart rate or bronchodilation, and they do have a physiologic effect.
