Abstract

The invention provides a high-capacity bromhexine hydrochloride sodium chloride injection composition. The bromhexine hydrochloride sodium chloride injection provided by the invention is prepared from bromhexine hydrochloride, sodium chloride, tartaric acid, glacial acetic acid and injection water. The bromhexine hydrochloride sodium chloride injection provided by the invention has the advantages of low content of related substances, high stability and the like.

Description

technical field [0001] The invention relates to the field of chemical pharmacy, in particular to a stable bromhexine hydrochloride sodium chloride injection composition and a preparation method thereof. Background technique [0002] Bromhexine Hydrochloride (BRH), that is, N-methyl-N-cyclohexyl-2-amino-3,5-dibromobenzylamine hydrochloride, is a modified structure of Vasicine The obtained semi-synthetic product has a strong effect of dissolving mucus, can crack mucopolysaccharide cellulose or mucin in sputum, and reduce the viscosity of sputum. Bromhexine hydrochloride is suitable for treating chronic bronchitis, asthma and other patients with thick sputum that is difficult to spit out. [0003] Compared with small injections, it is very necessary to directly use bromhexine hydrochloride large-volume injection for the convenience of clinical medication and to prevent secondary pollution during dispensing. At present, there is bromhexine hydrochloride large-volume injection ...
