Most potent bronchodilator among inhalational anesthetic agent is
Correct Answer: Halothane
Description: Halothane is considered a potent bronchodilator, as it often reverses asthma-induced bronchospasm. This action is not inhibited by b-adrenergic blocking agents. Halothane attenuates airway reflexes and relaxes bronchial smooth muscle by inhibiting intracellular calcium mobilization. Halothane also depresses clearance of mucus from the respiratory tract (mucociliary function), promoting postoperative hypoxia and atelectasis. Morgan clinical anesthesia 5e pg: 16
