Effects of chamomile extract nasal drop on chronic rhinosinusitis treatment: A randomized double blind study

Frequency and causes of self-medication in patients with chronic rhinosinusitis, North of Iran, 2018-2019

PURPOSE

Chronic rhinosinusitis (CRS) is a frequent respiratory disease. As self-medication is a common issue in the world, this study aimed to estimate its frequency in patients with CRS.

METHODS

144 CRS patients referred to a university hospital, were evaluated for self-medication, included type, duration, frequency, and its causes, their SNOT-22 questionnaire and Lund-MacKay scores. The data were analyzed using SPSS v.21 and the level of significance was considered as P ≥ 0.05.

RESULTS

30.6% of the cases used self-medication (65.9% used chemical drugs and 63.6% used herbal drugs), not associated with their age, gender, educational or economic level. The most common chemical drugs were antibiotics, analgesics and decongestants (75.9%, 55.2% and 10.3%, respectively) and the most common non-pharmaceutical agents included steam inhalation and herbal infusions (71.4%). The efficacy of self-medication was rated as "none" to "little" in 54.64% of cases. The mean SNOT-22 score was 59.54 ± 10.93 and 73.27 ± 8.12 in cases without and with self-medication (P = 0.034), and the mean Lund-MacKay score was 11.8 ± 5.3 and 17.2 ± 4.3 in cases without and with self-medication, respectively (P = 0.002). The top reasons for self-medication were "considering the disease unimportant" and believing chemical drugs being "harmful", "expensive", or "non-effective". Most patients who used self-medication did "not" advise it to others (80%).

CONCLUSION

The high rate of self-medication in CRS patients calls for greater attention to this issue in these patients. It seems that self-medication is significantly associated with more severe grades of disease and lower QOL in CRS cases.

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.
