Abstract

The invention belongs to the technical field of medicine, and particularly relates to an amorphous ambroxol hydrochloride compound and a preparation method thereof. The amorphous ambroxol hydrochloride compound has high purity and stability, does not have obvious moisture absorption and weight increase even under the condition of high humidity, ensures that relative substances do not grow, and has higher dissolution rate than crystalline ambroxol hydrochloride. The invention also relates to an application of the amorphous ambroxol hydrochloride compound in preparation of medicine for the treatment of acute and chronic pulmonary diseases with the symptom of ropy sputum and difficult expectoration, phlegm eliminating treatment of acute exacerbation of chronic bronchitis, asthmatic bronchitis and bronchial asthma, prophylactic treatment of lung complication after an operation, and treatment of infant respiratory distress syndrome (IRDS) of premature infants and neonates.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to an amorphous ambroxol hydrochloride compound and a preparation method thereof. Background technique [0002] Ambroxol hydrochloride is a mucus dissolving agent, also known as bromcycline hydrochloride, which is widely used in clinical practice due to its strong effect on eliminating phlegm and improving lung function. The drug can act on secretory cells, regulate the secretion of serous and mucus, increase serous secretion, dissolve and dilute mucus, strengthen the swing of cilia, increase the clearance ability of mucus transport system, and make sputum easy to discharge. Ambroxol hydrochloride is also a protective agent for the respiratory system, which has anti-oxidation, inhibits the release of inflammatory mediators, relaxes airway smooth muscle, and promotes the synthesis and secretion of pulmonary surfactant. Ambroxol hydrochloride can also increase the drug c...
