Comparison of Isotonic Seawater Nasal Spray Containing Chamomile Liquid Extract and Other Isotonic Seawater Nasal Washing Solutions for Allergic Rhinitis.

Objective We aim to demonstrate the effect of an isotonic seawater spray containing chamomile liquid extract on symptoms and nasal mucociliary clearance in patients with allergic rhinitis by comparing it with other isotonic seawater nasal washing solutions. Methods The study included 123 patients. Based on Allergic Rhinitis and its Impact on Asthma guidelines, mometasone furoate intranasal spray treatment was started for all patients in the group diagnosed with allergic rhinitis. In addition to this treatment, isotonic seawater spray with chamomile liquid extract was added to Group A, isotonic seawater spray to Group B, and isotonic seawater nasal irrigation to Group C. The fourth group (Group D) was given only nasal steroid spray without nasal washing treatment. Before and after treatment in all patients, the Sino-Nasal Outcome Test-22 was performed, and nasal mucociliary clearance times were measured by the saccharin test. Results The differences in duration of nasal mucociliary clearance and Sino-Nasal Outcome Test-22 values were taken before and after treatment. In Group A, B, C, and D the Sino-Nasal Outcome Test-22 differences were statistically significant (P ≤.001; P ≤ .001; P ≤ .001, and P = .048, respectively). Only Group A and Group B experienced a significant difference in nasal mucociliary clearance times (P ≤ .001; P = .010, respectively). When the Sino-nasal Outcome Test-22 score and nasal mucociliary clearance time differences before and after treatment were compared between all groups, the Sino-Nasal Outcome Test-22 score difference was higher in Group A than in Groups B, C, and D, the differences were found as statistically significant (P = .010; P = .003; P ≤ .001, respectively). The nasal mucociliary clearance time difference was higher in Group A than in Groups C and D, the differences were found as statistically significant (P = .010; P = .001, respectively). Conclusion Isotonic seawater spray containing chamomile liquid extract is seen as a good alternative treatment option for allergic rhinitis patients.
