Abstract

The invention belongs to the technical field of medicine, in particular to a composition of ambroxol hydrochloride and arginine and a preparation method thereof. The weight ratio of the ambroxol hydrochloride and the arginine in the composition is 1:0.01 to 0.8. The invention also provides a preparation method of freeze-dried powder preparation of the composition, and a use of the composition in the preparation of expectorant drugs.

Description

1. Technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to a composition of ambroxol hydrochloride and arginine, a preparation method thereof, and an application in preparation of drugs for treating expectorant. 2. Background technology [0002] Ambroxol (Ambroxol) is the active metabolite of bromhexine, the chemical name is trans-4-[(2-amino-3,5-dibromophenyl)]cyclohexanol, which is a respiratory lubricating expectorant Drugs and mucolytic drugs have the characteristics of promoting mucus elimination and dissolving secretions. It can promote the elimination of viscous secretions in the respiratory tract and reduce the retention of mucus, thus significantly promoting expectoration and improving respiratory conditions. It can promote the secretion of pulmonary surfactant, the secretion of airway fluid and the movement of cilia. Its preparation method and pharmacological effects have been published in US Patent No. 3,536,...
