A 24-year-old man experiences seasonal allergic rhinitis. Which type of drug is effective for short-term relief of his symptoms?

• A. B-Adrenergic agonist
• B. a-Adrenergic agonist
• C. Nicotinic cholinergic antagonist
• D. Muscarinic agonist

Answer: (B)

For someone experiencing seasonal allergic rhinitis, effective short-term relief of symptoms is typically achieved through the use of α-adrenergic agonists. These drugs act as decongestants, working to constrict blood vessels in the nasal passages, which reduces swelling and congestion. This action provides symptomatic relief by clearing nasal passages and improving airflow, making it easier for the patient to breathe.

While β-adrenergic agonists primarily target bronchial tissues and are more relevant in conditions like asthma, they are not particularly effective for rhinitis symptoms. Additionally, nicotinic cholinergic antagonists and muscarinic agonists do not have a pertinent role in alleviating nasal congestion or symptoms associated with allergic rhinitis.

In summary, the role of α-adrenergic agonists is significant in providing immediate relief for nasal congestion, making them the suitable option for treating acute symptoms of seasonal allergic rhinitis.
