评价单次、多次静脉滴注银杏内酯B注射液在中国健康受试者体内的安全性和耐受性

Previous clinical studies have confirmed that revascularization or recanalization rate after intravenous thrombolysis is closely related to the formation of thrombus, which also results in poor neurological function after thrombolysis. Platelet activating factor (PAF) strong platelet aggregation may be involved in thrombosis. Formation process. The main components of Ginkgolide injection (Ginkgo) are ginkgolide, ginkgolides A, ginkgolides B and ginkgolides C. Ginkgo biloba lactone can antagonize PAF and has strong anti-platelet aggregation. . Therefore, it can be speculated that ginkgolides injection combined with alteplase intravenous thrombolysis may improve the recanalization rate after thrombolysis and reduce the reocclusion rate.
In addition, clinical studies have also found that ginkgolide injection has a good auxiliary effect on hypertensive intracerebral hemorrhage, which can regulate inflammatory factors such as IL-6, TNF-α and high-sensitivity C-reactive protein (CRP) in patients. Recovery of neurological function in patients. It is well known that TNF-α, IL-β, IL-1, IL-6, IFN-γ, etc. are all inflammatory factors associated with reperfusion injury. Therefore, we speculate that ginkgolides injection may also regulate inflammatory factors associated with reperfusion injury, such as IL-6, TNF-α, thereby reducing reperfusion injury, thereby improving patient prognosis.
The aim of this study was to determine the clinical efficacy of ginkgolides injection combined with alteplase in the treatment of acute ischemic stroke, and to improve the prognosis of patients with thrombolysis.
