Evaluation of Bactorinol® Nasal Spray in Adult Patients With Vasomotor Rhinitis

Vasomotor rhinitis is a chronic inflammatory condition of the nasal mucosa characterized by airflow obstruction, dysregulated mucus production, and impaired mucociliary clearance. Environmental factors, mucosal dryness, and alterations in epithelial function contribute to symptoms, and current treatment options are often limited or unsatisfactory. Bactorinol® nasal spray is a medical device formulated with winterized Pistacia lentiscus oil, which contains terpenes and polyphenols with recognized emollient, anti-inflammatory, antibacterial, and antibiofilm properties. These characteristics may help reduce mucosal irritation, improve mucociliary function, and relieve nasal congestion. This multicenter, prospective, randomized, controlled, parallel-group clinical trial will enroll 100 adults with a confirmed diagnosis of vasomotor rhinitis. Participants will be randomized 1:1 to receive either Bactorinol® nasal spray (3 puffs per nostril, three times daily) or isotonic saline solution with the same dosing schedule, for 20 days. The primary endpoint is the change in nasal airflow as measured by Peak Nasal Inspiratory Flow (PNIF) from baseline to the end of treatment. Secondary assessments include changes in quality of life measured by the SNOT-22 questionnaire, nasal cytology via rhinocytogram, treatment compliance, and adverse events. Clinical and cytological evaluations will be performed at baseline and at the end of the 20-day treatment period. The study is designed to determine whether Bactorinol® provides clinically meaningful improvement in nasal breathing and symptom burden in patients with vasomotor rhinitis and to assess its safety and tolerability when used as directed.
