  • Patent number: 11857520
    Abstract: A nasal spray formulation and a method of using a locally acting sodium channel blocker to treat pain is disclosed, wherein the nasal spray formulation comprises from about 5% to about 30% w/v of a locally active sodium channel blocker, from about 0.25% to about 5% w/v of a buffering agent, and from about 5 to about 99% w/v of a pharmaceutically acceptable carrier for nasal administration. The nasal spray formulation is preferably contained in a mechanical multi-dose pump which sprays a unit dose of the nasal spray formulation with a wide plume and small droplet size, such that the unit dose is administered by actuating the mechanical multi-dose spray pump device and spraying a volume of the nasal spray formulation into each nostril of a human subject. Preferably, the nasal spray formulation does not include a preservative.
