Résumé
Patients suffering from allergic rhinitis seek for several therapeutic symptomatic options, including nonconventional treatments, to control their symptoms.
Through the present proof-of-concept study, we prospectively investigated the potential role of Puressentiel® nasal protection spray (SNPA) in patients suffering from cypress pollen allergic rhinitis.
In 15 adults, we performed two nasal provocation tests, with a cypress pollen extract, with a 15-day interval, with and without previous randomized administration of SNPA, and evaluated a nasal symptom score, the nasal inspiratory peak flow, and the concentration of inflammatory cytokines in the nasal lavage after the procedures.
Comparing results in patients challenged with and without the SNPA spray before the nasal challenge, we found a 57% mean decrease in symptoms, and a 62% average difference in inspiratory peak flow, after the use of the spray.
Puressentiel® SNPA is effective in reducing nasal symptoms, as assessed by nasal symptoms score and nasal inspiratory peak flow, and could be a valid natural non-pharmacological option in patients suffering from allergic rhinitis.
