Which class of drugs does terbutaline belong to?

• A. Antihistamines
• B. Beta-agonists
• C. Calcium channel blockers
• D. Prostaglandins

Answer: (B)

Terbutaline is classified as a beta-agonist, specifically a beta-2 adrenergic agonist. This class of drugs is primarily used for their bronchodilator effects, making them effective in managing conditions such as asthma and chronic obstructive pulmonary disease (COPD). In the context of maternal and pediatric care, terbutaline can also be used to relax uterine smooth muscle, thereby inhibiting premature labor. The mechanism of action involves the stimulation of beta-2 receptors in the bronchial smooth muscle, leading to dilation of the air passages and providing relief from bronchospasm. While antihistamines are used primarily for allergic reactions, calcium channel blockers affect smooth muscle contraction differently, and prostaglandins have roles in inducing labor and regulating various physiological processes. Understanding the unique role of beta-agonists like terbutaline is essential for effective treatment in both respiratory conditions and managing preterm labor.
