A kind of pharmaceutical composition for preventing and treating covid-19 and preparation method thereof

Abstract

The invention belongs to the field of medical technology, and in particular relates to a pharmaceutical composition for preventing and treating COVID-19 (a disease caused by a novel coronavirus) and a preparation method thereof. The pharmaceutical composition comprises Mycobacterium vaccae and salbutamol sulfate for injection The active ingredient, its composition and weight ratio are: mycobacterium vaccae for injection: salbutamol sulfate is 1:50-200. The medicine made from the pharmaceutical composition can be treated by aerosol inhalation. Through short-term aerosol inhalation, providing patients with this special-purpose medicine can improve patient compliance, make medication convenient for patients, and reduce medical expenses. . The pharmaceutical composition for the prevention and treatment of COVID-19 described in the present invention can not only effectively prevent and treat COVID-19, reduce the patient's conversion to severe or critical illness, shorten the average time of negative nucleic acid conversion by about 4 days, and shorten the treatment time accordingly. The non-specific prevention and treatment of other respiratory viral infections provides new ways and solutions for the clinical prevention and treatment of COVID‑19 and respiratory viral infections.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a pharmaceutical composition for preventing and treating COVID-19 (a disease caused by a novel coronavirus) and a preparation method thereof. Background technique [0002] Interferon (IFN) is the most important and possibly the only natural non-specific antiviral natural component in the body. IFN is currently the most important non-specific antiviral component found and recognized in the body, which is divided into type I (IFN-β and IFN-α), type II (IFN-γ) and type III (IFN-λ1, IFN- λ2, IFN-λ3) IFN. After IFN is produced, it activates the intracellular JAK-STAT pathway at the infected site, regulates the transcription of hundreds of related effector antiviral genes (ISGs), thereby inhibiting virus proliferation, promoting apoptosis of infected cells, and allowing uninfected cells to enter Antiviral status, IFN can also promote the maturation of various innate immu...

Problems solved by technology

At present, in the latest diagnosis and treatment plan ("Diagnosis and Treatment Plan for Pneumonia Infected by Novel Coronavirus (Trial Version 5 and 6)" issued by the National Health and Health Commission on January 27, 2020), nebulized inhalation of α-IFN (500 mg per adult for adults) is recommended. 10,000 U, add 2ml of sterile water for injection, twice a day), but its actual therapeutic effect is still uncertain. Consider its high cost and whether aerosol inhalation of α-IFN can reach the lower respiratory tract and lung tissue
