Proponent Nasal Spray

Proponent Nasal Spray is a medical device developed by PRECLIN Biosystems AG for the treatment of unspecific nasal discomfort, including symptoms like dryness, irritation, and congestion. The spray's primary active component is ectoine, a natural extremolyte that forms a stable water layer known as the Ectoin-Hydro-Complex on the nasal mucosa. This layer acts as a physical barrier that stabilizes cell membranes and protects the underlying tissue from allergens and other environmental stressors. By facilitating the regeneration of the nasal epithelium and reducing inflammation through physical means, Proponent Nasal Spray provides immediate symptom relief. It has been evaluated in open-label observational studies to confirm its efficacy and safety in adult patients.
