What type of medication is Serevent Diskus (salmeterol)?

• A. Long acting beta 1 agonist
• B. Long acting beta 2 agonist
• C. Short acting beta 2 agonist
• D. Short acting beta 1 agonist

Answer: (B)

Serevent Diskus, which contains the active ingredient salmeterol, is classified as a long-acting beta 2 agonist. This categorization is significant because beta 2 agonists are primarily used in the management of asthma and chronic obstructive pulmonary disease (COPD) due to their action on the bronchial smooth muscle, leading to bronchodilation. Salmeterol works by binding to beta 2 adrenergic receptors, which are predominantly located in the respiratory tract. As a long-acting agent, it provides sustained bronchodilation lasting up to 12 hours or more, making it suitable for maintenance therapy in patients with chronic respiratory conditions. This contrasts with short-acting beta 2 agonists that are typically used for quick relief during asthma attacks. Understanding the classification of salmeterol is crucial for both safe prescribing and effective treatment planning for patients with respiratory issues, as it helps distinguish between medications that provide immediate relief versus those that prevent symptoms over an extended period.
