Description

technical field [0001] The invention relates to the field of medicines, in particular to the application of a pharmaceutical composition in the preparation of antiviral medicines. Background technique [0002] Upper respiratory tract infection is called upper respiratory tract infection for short, also known as common cold. It is a general term including acute inflammation of the nasal cavity, pharynx or larynx, 70-80% of which are caused by viral infections, including influenza virus, rhinovirus, coronavirus, adenovirus, influenza and parainfluenza virus, respiratory syncytial virus, echo virus, Coxsackie virus, etc. [0003] At present, most of the antiviral drugs used to treat upper respiratory tract infection are synthetic drugs, such as ribavirin and oseltamivir, etc., which may cause drug resistance of the virus during long-term use, resulting in mediocre antiviral efficacy , And the side effects are large. In view of this, this patent is proposed. Contents of the...
