Antiviral drug. It has the effect of inhibiting the growth of many viruses such as respiratory syncytial virus, influenza virus, hepatitis A virus, adenovirus, etc. in vitro, and its mechanism is not fully understood. This product does not change the adsorption, invasion and uncoating of viruses, nor does it induce the production of interferon. After entering the virus-infected cells, the drug is rapidly phosphorylated, and its product acts as a competitive inhibitor of viral synthase, inhibiting inosine monophosphate dehydrogenase, influenza virus RNA polymerase and mRNA guanosine transferase, thereby causing a decrease in intracellular guanosine triphosphate, impairing viral RNA and protein synthesis, and inhibiting viral replication and transmission. It may also have an immune effect and neutralizing antibody effect on respiratory syncytial virus.

This product is an adrenal cortex hormone drug. It has multiple pharmacological effects such as anti-inflammatory, anti-allergic and immunosuppressive. Its main mechanisms are: 1. Anti-inflammatory effect: Glucocorticoids reduce and prevent tissue response to inflammation, thereby reducing the manifestation of inflammation. 2. Anti-allergic and immunosuppressive effects: prevent or inhibit intermediate immune responses, delayed allergic reactions, and reduce the expansion of primary immune responses.

It has the effect of directly stimulating vascular α1 receptors and causing vasoconstriction, thereby alleviating congestion and edema caused by inflammation.

Has anti-inflammatory and anti-allergic effects

This product is a broad-spectrum antibiotic that has antibacterial effects on most Gram-negative and some Gram-positive bacteria. Its mechanism of action is to inhibit bacterial protein synthesis.
