Competitively inhibit the adsorption of plasminogen on fibrin, prevent its activation, protect fibrin from being degraded and dissolved by plasmin, and achieve hemostatic effect; directly inhibit plasmin activity, reduce the effect of plasmin activating complement, and prevent the occurrence of hereditary angioedema.

Competitively inhibit the adsorption of plasminogen on fibrin, prevent its activation, protect fibrin from being degraded and dissolved by plasmin, and achieve hemostatic effect; at the same time, directly inhibit the activity of plasmin, reduce the effect of plasmin in activating complement, and prevent the occurrence of hereditary angioedema.

This product is a non-peptide endothelin receptor antagonist, which can antagonize endothelin-induced vasoconstriction, blood pressure increase and vascular smooth muscle cell proliferation, reduce vascular endothelial damage; increase NO synthesis, relax vascular smooth muscle; inhibit platelet aggregation, anti-coagulation, and improve blood rheology characteristics. This product can also inhibit cholesterol synthesis, lower blood lipids, scavenge free radicals, prevent lipid peroxidation damage; affect complement, enhance immune function, and have certain analgesic and antispasmodic effects.

This product is an opioid receptor antagonist, which has almost no pharmacological activity itself, but can competitively antagonize various opioid receptors and has a strong affinity for m receptors. It can completely or partially correct the central inhibitory effects of opioid substances, such as respiratory depression, sedation and hypotension; it has a wake-up effect on animals with acute ethanol poisoning; it is a pure opioid receptor antagonist and does not cause respiratory depression, psychotomimetic reactions or miotic reactions; there is no drug resistance, nor physiological or mental dependence.
