Abstract

The invention belongs to the field of a medicine preparation and relates to an inhalant acetylcysteine solution and a preparation method of the inhalant acetylcysteine solution. Physiological seawater is added into the solution, so that the sensitization of the acetylcysteine solution is effectively reduced.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to an acetylcysteine ​​solution for inhalation and a preparation method thereof. Background technique [0002] Acetylcysteine ​​(acetylcysteine, NAC), the chemical name is N-acetyl-L-cysteine, is the acetyl compound of L-cysteine, and its molecular weight is 163.2, because it contains active sulfhydryl (- SH), was used clinically as an expectorant in the early 1960s, and is an expectorant for the treatment of respiratory infections with good curative effect and high safety. Its molecular formula is as follows: [0003] [0004] Acetylcysteine, as a cysteine ​​derivative, is a mucolytic drug, mainly through the sulfhydryl group in the molecule to break the disulfide bond (-S-S-) of the acidic glycoprotein polypeptide in the mucus sputum, purulent sputum The DNA lysis in the middle can exert a strong sputum dissolving effect on white sticky sputum or sticky sputum purul...
