Rhinosinusitis Treatment with Cineole: Patient-Reported Quality of Life Improvements from a Non-Interventional, Pharmacy-Based Survey.

Abstract

Rhinosinusitis is commonly treated with decongestants, analgesics, and local corticosteroids. Phytotherapeutics are also utilised for symptomatic relief, including cineole, the main component of eucalyptus oil. The current non-interventional, anonymised survey investigated quality of life in participants with rhinosinusitis (with or without additional symptoms of bronchitis) via the German version of a validated quality of life questionnaire (RhinoQol). Overall, 310 subjects administered a cineole preparation (Sinolpan) and 40 subjects applying nasal decongestant were recruited in German pharmacies. Significant improvements in frequency (64.0%), bothersomeness (52.1%), and impact (53.9%) of rhinosinusitis symptoms were reported upon treatment with cineole over a mean treatment period of seven days (p < 0.001 each). The overall treatment efficacy of cineole was evaluated as good or very good by 90.0% of the participants, and the quality of life during work or leisure time improved upon treatment. Six (non-serious) possibly related side effects were reported in four participants who were administered cineole. The tolerability of the treatment was assessed as good or very good by 93.9% of the participants. Cineole can be considered as a safe and well-tolerated rhinosinusitis treatment conferring a clear improvement in quality of life outcomes.
