Abstract
The invention discloses a pharmaceutical composition for preventing and / or treating inflammatory storm, a preparation and application thereof. The pharmaceutical composition is prepared from baicalein, wogonin and oroxylin A, and the mass ratio of the baicalein to the wogonin to the oroxylin A is (0.25-1.5):(0.5-7):1. The self-microemulsion provided by the invention comprises the following components: a drugphospholipid complex, an oil phase, an emulsifier and a co-emulsifier, wherein the drugphospholipid complex is formed by compounding the medicine composition and a phospholipid material. Experimental results show that in an LPS-induced systemic inflammationstorm mouse model, the composition of the baicalein, the wogonin and the oroxylin A and the self-microemulsion preparation of the composition have the effects of inhibiting mouse cytokinestorm to different degrees. The pharmaceutical composition for preventing and / or treating inflammatory storm, the preparation and the application thereof provide a safe, effective and economical solution for clinical treatment of inflammatory storm.
Description
technical field [0001] The invention belongs to the field of medicine, and in particular relates to a pharmaceutical composition for preventing and / or treating inflammatory storm, its preparation and application. Background technique [0002] Inflammatory storm is an excessive immune response and inflammatory response of the body to external stimuli, characterized by the excessive proliferation of T cells and macrophages and the rapid release and overexpression of inflammatory cytokines. Inflammatory storms can be caused by many infectious or noninfectious diseases, such as influenza, new coronary pneumonia (COVID-19), Middle East respiratory syndrome (MERS-CoV), atypical pneumonia (SARS), familial hemophagocytic syndrome, sepsis, systemic Juvenile idiopathic arthritis (sJIA), chimeric antigen receptor (CAR)-T cell therapy and lupus erythematosus, etc. [0003] The inflammatory storm phenomenon caused by respiratory virus infection such as influenza virus and coronavirus is...
