Problems solved by technology

Respiratory tract infection is often accompanied by phlegm, and a large amount of sputum affects the absorption of drugs, thereby affecting the therapeutic effect
At present, in the clinical treatment of respiratory tract infections, single-use antibiotics (such as azithromycin) or expectorants (such as ambroxol hydrochloride, erdosteine, etc.) are often used, and the dosage is relatively large; The method of compatibility of expectorant preparations is used to treat respiratory tract infection diseases, but often the dosage of compatibility application is not accurate enough
In a word, the drugs in the existing treatment methods have disadvantages such as poor curative effect, large dosage, and difficult dosage control.

Abstract

The present invention relates to a compound medicine preparation for curing acute and chronic respiratory tract infection. It is made up by using azithromycin and phlegm-removing active component according to the weight mixing ratio of 1:0.05-2.

Description

Technical field: [0001] The invention relates to a medicine, in particular to a compound chemical medicine preparation for treating acute and chronic respiratory infections. technical background: [0002] Respiratory tract infection is a common infectious disease. The pathogenic microorganisms are mainly bacteria, followed by viruses and mycoplasma. my country is a country with a high incidence of bacterial infectious diseases. Due to factors such as air pollution, the number of children infected is particularly high. Respiratory tract infection is often accompanied by phlegm, and a large amount of sputum affects the absorption of drugs, thereby affecting the therapeutic effect. At present, in the clinical treatment of respiratory tract infections, single-use antibiotics (such as azithromycin) or expectorants (such as ambroxol hydrochloride, erdosteine, etc.) are often used, and the dosage is relatively large; The method for the compatibility of expectorant preparations is...
