Dicaine foaming compound anesthetic

Abstract

The present invention relates to a dicaine foaming compound anesthetic capable of foaming and expanding in cavity organs of nasal cavity, slowly and uniformly releasing and making full surface anesthesia. It is an mixed preparation which is made up by using water and water soluble polymer as carrier, using high-pressure nitrogen gas as propellant and dissolving caine or dicaine and vasoconstrictor in carrier. At the same time of making full surface anesthesia it can reduce irritation due to caine cotton pieces filled in the nasal cavity and mucous damage, and can fully fill any narrow cavity position so as to reduce pain of patient and labour intensity of doctor, and its preparation method is simple.

Description

Technical field: [0001] The invention relates to a new dosage form of caine, in particular to a caine foaming compound anesthetic capable of foaming and expanding in nasal cavity and other cavity organs, releasing slowly and evenly, and fully anesthetizing. Background technique: [0002] At present, the known caine topical anesthetic has two dosage forms of 1-2% aqueous solution and colloidal solvent. Taking the traditional topical nasal mucosal anesthesia method as an example, it needs to use cotton pads as the carrier. After soaking with caine, the cotton pads are repeatedly stuffed on the surface of the nasal mucosa for 1-3 times. The disadvantages of this method are: strong irritation and easy damage The mucous membrane, and the narrow lumen is difficult to fully fill, and the dosage of anesthetic drugs is difficult to control, which will cause adverse consequences such as excessive anesthetics and poisoning. Invention content: [0003] In order to overcome the shortc...
