Question

which of the following is a long acting beta adrenergic maintenance agent in dpi form? accolate xopenex serevent epinephrine

Explanation:

To determine the long - acting beta - adrenergic maintenance agent in DPI (Dry Powder Inhaler) form:

• Accolate is a leukotriene modifier, not a beta - adrenergic agent.
• Xopenex is a short - acting beta - adrenergic agonist (SABA), used for acute relief rather than long - term maintenance.
• Serevent (salmeterol) is a long - acting beta - 2 adrenergic agonist (LABA) and is available in DPI form for maintenance therapy of asthma and COPD.
• Epinephrine is a short - acting agent, mainly used in emergency situations like anaphylaxis, not as a long - term maintenance agent in DPI form.

Answer:

C. Serevent
