Problems solved by technology

[0004] At present, there is no clinical preparation for the treatment of combined infection. The antibacterial infection and antifungal infection programs are administered separately. The repeated and alternate use of the two types of drugs makes the administration cumbersome and the treatment time is long, which brings inconvenience to clinical use. Also bring the misery of administration to the patient, therefore, urgently need a kind of pharmaceutical composition that can bring into play the effect of antibacterial infection and antifungal infection simultaneously, facilitate clinical use, improve patient's adaptability

Abstract

The invention relates to a medicinal composition for treating complex infection and a preparation method thereof. The medicinal composition is characterized by comprising an active ingredient selected from one of glycopeptides antibacterial drugs of telavancin, dalbavancin, oritavancin, vancomycin, teicoplanin or a pharmaceutically acceptable salt thereof, and also comprising polyene and echinocandin type antifungal agents, and being prepared into a freeze-dried powder injection by adopting a conventional process. The medicinal composition provided by the invention realizes combined application of the antibacterial drugs and the antifungal agents, can simultaneously give play to an antibacterial infection effect and an antifungal infection effect, and is convenient for clinical use.

Description

Technical field: [0001] The invention belongs to the technical field of medicine preparation, and specifically relates to a composition containing glycopeptide antibacterial medicines and antifungal medicines and a preparation method thereof. Background technique: [0002] With the wide application of antibiotics, antineoplastic drugs, immunosuppressants and traumatic diagnosis and treatment techniques and the increase in the incidence of immunodeficiency syndrome, the number of patients with bacterial and fungal co-infection is increasing. For example, patients with hematological tumors, diabetes, and AIDS often have bacterial and fungal infections. Pathogens are often Candida albicans, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus enterica, etc., and most of them are multi-drug resistant bacteria. Treatment is very tricky, causing the disease to worsen and the mortality rate to increase. [0003] Glycopeptide antimicrobials vancomycin and teicoplanin a...
