Abstract

The invention provides a drug for treating bronchitis and a preparation method thereof. The drug is prepared from esterified mangiferin, sodium houttuyfonate, acidized berberine, wormwood essential oil, an extract of orange peel, an extract of Guangxi leaf of strigose hydrangea and succinic acid, and the main components of mangiferin, berberine and various kind of essential oil are subjected to microencapsulation. Absorption of the drug by human body can be improved, the performing time of the drug can be longer through drug sustained release, the respiratory tract function can be effectivelyimproved so that respiration can be smooth, and meanwhile, the drug has the antiviral effect.

Description

technical field [0001] The invention belongs to the technical field of medicine preparation for respiratory diseases, in particular to a medicine for treating bronchitis and a preparation method thereof. Background technique [0002] Bronchitis refers to chronic non-specific inflammation of the trachea, bronchial mucosa and surrounding tissues. The main cause of bronchitis is chronic non-specific inflammation of the bronchi formed by repeated infections of viruses and bacteria. When the temperature drops, the spasm and ischemia of small respiratory vessels, and the decline in defense function are conducive to pathogenesis; chronic stimuli such as smoke and dust and air pollution can also cause disease; smoking can cause bronchospasm, mucous membrane variation, decreased ciliary movement, and increased mucus secretion, which is conducive to infection; allergies factors are also relevant. In today's society, the environment is increasingly polluted, leading to more and more ...
