Which of the following sympathomimetics is a selective Beta-2 agonist commonly used to treat acute bronchospasm?
Show answer and explanation
Correct answer: Salbutamol (Albuterol)
Salbutamol is a short-acting beta-2 agonist (SABA) that causes rapid relaxation of bronchial smooth muscle. Its selectivity for beta-2 receptors over beta-1 receptors minimizes unwanted cardiac side effects like tachycardia at therapeutic doses.
