Can the Nasal Cavity Help Tackle COVID-19?
"found out the components within the Xlear nasal sprayTM, particularly grapefruit seed extract (GSE) and xylitol, were successful in statistically significant reduction of the viral load of SARS-CoV-" "5.9. Nasal Delivery of Hypochlorous Acid
Hypochlorous acid (HClO), which is known as a potent broad-spectrum antibacterial agent, has shown strong antimicrobial (antibacterial, fungicidal or virucidal) effect in nasal formulations ... a unique Acid-Oxidizing solution (AOS2020) containing pure and stable HClO in a liquid carrier solution, using APR’s Tehclo™ nanotechnology delivery platform, which entraps HCLO in an aqueous solution, enabling its inhalation. AOS2020 comprises a hypotonic solution with unique physicochemical characteristics in terms of pH 2.5–3, oxidative reduction potential 1000–1200 mV and free chlorine species of which pure HClO is not less than 95%... The study involves COVID-19 patients with mild symptoms of the disease and aims at evaluating the efficacy and safety of the spray product in reducing viral load in the upper respiratory airways in recently infected individuals. Results, when available, could represent an additional near-term protective option that could be particularly helpful in high-risk environments."
