French company Valois has developed an intranasal spray that doesn’t require preservatives to maintain the quality of the product inside of them. Such preservatives often irritate the mucous membranes while also reducing and blocking the process of mucociliary clearance—nature’s way of protecting our upper airways. The system, code-named VPY, uses a closed-pump architecture that allows the medicinal formulation to occur absent any ambient air that might contaminate it. No word on if a similar system could be used to prevent those pesky coke-induced nosebleeds, but the new system should make it to market within a few years, pending FDA approval, natch.
