FOAMING COMPOSITIONS AND METHODS FOR DELIVERING ACTIVE AGENT INTO BODY CAVITY Russian patent published in 2019 - IPC A61K9/12 A61K47/44 

FIELD: medicine; pharmaceuticals.

SUBSTANCE: group of inventions refers to pharmaceutics, particularly to drug delivery systems, and discloses a foaming composition and a method of treating an infection. Foaming composition is characterized by that it contains hydrogen peroxide, monoglyceride crystals, at least one acid and/or buffer, which are present in an amount required to provide pH from 3 to 5 in the body cavity, a blowing agent in an amount sufficient to blow the foaming composition and formation of foam, and water. Foaming composition is suitable for application in the body cavity during blowing with formation of foam, the foam is destroyed at body temperature with releasing hydrogen peroxide in the body tissue at pH from 3 to 5 and represents a carrier in the form of a foaming composition for the active agent delivery.

EFFECT: foaming composition is a delivery system capable of treating the entire body cavity surface due to its solid crystalline structure and can be used to treat an infection in the body cavity.
