Problems solved by technology

Moreover, Houttuynia cordata injection is generally placed in glass ampoules, which is troublesome to open and inconvenient to store, and needs to be filled in nasal drops or nasal spray devices, which cannot be conveniently used by patients with nasal inflammation
Therefore, the dosage form of Houttuynia cordata injection is not suitable for treating rhinitis and sinusitis. It is necessary to develop a new Houttuynia nasal preparation

Abstract

A medicnie for treating rhinitis and nasosinusitis is prepared from houttuynia, polysorbide, sodium hydrogen sulfite, antiseptic, sodium chloride, purified water and pH regulator through distilling houttuynia to extract its active components, proportionally mixing them with others, filtering, and steam sterilizing.

Description

technical field [0001] The invention relates to a medicine for treating acute and chronic rhinitis, sinusitis, rhinitis sicca, atrophic rhinitis, epistaxis and other nasal inflammation diseases, or after nasal surgery, specifically a Houttuynia nasal preparation and its production process. Background technique [0002] Rhinitis and sinusitis are common, frequently-occurring and difficult diseases in the Department of Otolaryngology. They are infectious inflammations caused by local lesions in the nasal cavity caused by viruses or bacteria or infected lesions in adjacent organs of the nasal cavity. Acute and chronic rhinitis are respectively called "nasal congestion" and "nasal choking" in traditional Chinese medicine theory. "Cold and nasal congestion" is caused by wind-cold or wind-heat evil blocking the lung system and invading the nasal orifices. It is related to the disorder of the two viscera and Yangming meridians or blood stasis and turbid ph...
