Patients suffering from rhinitis and rhinosinusitis often experience symptoms such as nasal discharge, congestion, sniffles, and excess phlegm secretion. These symptoms can cause a feeling of impaired airflow, loss of patency, and uncomfortable breathing. In this context, a treatment method is proposed to alleviate these signs and symptoms. The drug target is the TRPM8 receptor on nerve fibers of the ostiomeatal complex. The active ingredient, a TRPM8 agonist, is delivered using an electronically controlled nebulizer that produces a vigorous air plume of defined particle sizes, which prevents entry into the lungs. The quantity of phlegm expelled from the nasal passage is used as an index of anti-inflammatory effectiveness. The optimized drug candidates for delivery and therapy are from a group of p-menthanecarboxamides. Preferred embodiments of these include the p-menthane amino acid esters: GlyOnPr, GlyOiPr, D-Ala-OnPr, and D-Ala-OiPr, delivered as a liquid suspension or solution at 0.1 to 1% (1 to 10 mg / mL), 0.5 to 0.8 mL per nostril over 3 to 5 seconds, using a nebulizer. This regimen, administered three times per day for three to five days, will help the patient manage and control their nasal congestion and phlegm secretion, and sleep better at night. The preferred embodiments delivered into the nasal cavity create a sense of cool breathing, refreshing coolness, and a feeling of negative heat flux, like an air conditioner in the nose. The secretion of phlegm is clearly decreased, as measured with a top-loading balance. This pharmacological treatment for patients with nasal inflammation has the potential to alter the course of rhino-disorders permanently.
