Abstract

The invention belongs to the technical field of medicine and particularly relates to a sevoflurane inhalant which contains sevoflurane, peppermint oil and ethanol and is prepared through the following method: dissolving peppermint oil in ethanol to form a solution, adding the solution in sevoflurane to form a mixture, and filling the mixture in a glass bottle. Compared with the prior art, the technology is simple, and the stability is excellent.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a sevoflurane inhalation agent. Background technique [0002] The compound sevoflurane (1,1,1,3,3,3-hexafluoroisopropylfluoromethyl ether or hexafluoroisopropylfluoromethyl ether or (CF3)2CHOCH2F) is a widely used inhalational anesthetic, especially Suitable for outpatient surgery. Therefore, a cost-effective method for the preparation of stable sevoflurane is highly desired. [0003] A number of methods for the preparation of sevoflurane have been described, many of which have limited commercial application. U.S. Patent 3,683,092 describes four preparations, three of which start with 1,1,1,3,3,3-hexafluoroisopropylmethyl ether (reaction with potassium fluoride in sulfolane or with bromine trifluoride reaction), one starting with 1,1,1,3,3,3-hexafluoroisopropanol (reaction with formaldehyde and hydrogen fluoride). US Patent 3,897,502 describes the direct fluorina...
