Abstract

The present invention discloses a bromhexine hydrochloride injection and its preparation method. It is prepared by using bromhexine hydrochloride and medicinal carrier, and can be directly used for intravenous injection.

Description

technical field [0001] The invention relates to an injection and a preparation method thereof, in particular to a bromhexine hydrochloride injection and a preparation method thereof. Background technique [0002] Bromhexine hydrochloride is the preferred expectorant commonly used at home and abroad. It can decompose and break the acidic mucopolysaccharide fibers in sputum, and inhibit the synthesis of acidic mucopolysaccharides by glandular goblet cells, thereby reducing the viscosity of sputum and making it easier to cough up. This product still has nausea expectorant effect. It is mainly used for chronic bronchitis, asthma, bronchiectasis, silicosis and other patients with white sticky sputum that is difficult to cough up; it is especially suitable for surgical operations and critically ill patients. At present, there are dosage forms such as water injection and tablet for clinical use. There are bromhexine hydrochloride raw materials and tablets on page 691-693 of the ...
