Persistent allergic rhinitis in children is commonly treated with intranasal corticosteroids (INS), which are considered first-line therapy. However, the delayed onset of action of INS may reduce patient adherence and delay symptom relief. This randomized controlled study evaluates whether adding short-term oxymetazoline nasal spray during the first 5 days of INS treatment ("bridge therapy") improves clinical outcomes, nasal airflow, quality of life, nasal inflammation, and medication adherence in children with persistent allergic rhinitis.
Children aged 4-18 years with moderate-to-severe persistent allergic rhinitis were randomized into two parallel groups. One group received mometasone furoate nasal spray alone for 4 weeks, while the other group received mometasone furoate combined with oxymetazoline during the first 5 days of treatment. Clinical symptoms, Peak Nasal Inspiratory Flow (PNIF), Pediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ), Nasal Nitric Oxide (nNO), and Medication Adherence Rating Scale (MARS) scores were evaluated.
