What route of administration is effective for administering intranasal antihistamines?

• A. Oral
• B. Topical
• C. Intravenous
• D. Intranasal

Answer: (D)

The effective route of administration for intranasal antihistamines is intranasal itself. This method delivers the medication directly into the nasal passages, where it can exert its action more rapidly and efficiently on the relevant histamine receptors involved in allergic responses. By bypassing the systemic circulation, intranasal administration can also minimize potential side effects that may arise with oral or intravenous routes. Using intranasal antihistamines directly targets the site of allergen exposure and can provide quicker relief from symptoms such as sneezing, itching, and congestion associated with allergic rhinitis. This route is advantageous for patients who may have difficulty swallowing tablets or for those who prefer a localized treatment approach that can quickly address nasal symptoms without the need for systemic mediation.
