Pharmaceutical composition for preventing and treating COVID-19 and preparation method of pharmaceutical composition

The invention belongs to the technical field of medicines. The invention relates to a pharmaceutical composition, in particular to a pharmaceutical composition for preventing and treating COVID-19 (diseases caused by novel coronaviruses) and a preparation method thereof. The pharmaceutical composition comprises active ingredients of mycobacterium vaccae for injection and salbutamol sulfate, and the weight ratio of the mycobacterium vaccae for injection to the salbutamol sulfate is 1: (50-200). The medicine prepared from the medicine composition can adopt an aerosol inhalation treatment mode, and through short-term aerosol inhalation, the compliance of a patient can be improved by providing the medicine with a specific purpose for the patient, so that the patient can take the medicine conveniently, and the medical cost is reduced. The pharmaceutical composition for preventing and treating COVID-19 disclosed by the invention has the advantages that the COVID-19 can be effectively prevented and treated; severe or critical symptoms of patients are relieved, nucleic acid negative conversion time is shortened by about 4 days averagely, treatment time is correspondingly shortened, other respiratory virus infections can be prevented and treated nonspecifically, and a new way and scheme are provided for clinical prevention and treatment of COVID-19 and respiratory virus infections.

Alendronate sodium powder inhalation used for respiratory drug delivery and preparation method and application thereof

The invention provides alendronate sodium powder inhalation used for respiratory drug delivery and a preparation method and application thereof. Alendronate sodium powder inhalation includes single-component alendronate sodium micro powder and does not include auxiliary materials. In the production and preparation process of the alendronate sodium micro powder, other auxiliary materials or solvents are not involved, and alendronate sodium raw material medicine is directly smashed to prepare the alendronate sodium micro powder. The alendronate sodium powder inhalation can improve the breathing function of a chronic obstructive pulmonary disease (COPD) rat by about 40% and has a better effect than salbutamol sulfate with a common usage amount, and drug resistance of salbutamol sulfate and other beta2 receptor stimulants can be eliminated. The powder inhalation mainly makes sedimentation in the trachea, bronchia, bronchiole and other pulmonary respiratory ducts to directly take effect after drug-delivery inhalation, the diastolic function of the respiratory ducts becomes effective rapidly, and the drug effect lasts for a long time; the alendronate sodium powder inhalation enters pulmonary alveoli, is low in absorption and blood-entering amount, can avoid systematic side effects and is suitable for being developed to be a drug for treating COPD and asthma.
