What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 66 participants in total. It began in 2025-09-15 with a primary completion date of 2028-09-14.

Brief Summary

Although mechanical thrombectomy or thrombolytic therapy for large vessels can achieve a revascularization rate (TICI ≥2b) of over 90%, 30-50% of patients still exhibit poor functional outcomes. This phenomenon of "ineffective reperfusion" suggests that microcirculatory dysfunction plays a decisive role in post-stroke neural injury. Therefore, it is necessary to combine brain protection strategies with microcirculatory reperfusion therapy to improve the functional prognosis of stroke patients.Increasing cerebral blood flow (CBF) and neurovascular unit (NVU)-based cerebral protection are current hotspots in the emergency treatment of stroke. Galantamine, extracted from Lycoris aurea (a traditional Chinese medicinal herb), is an acetylcholinesterase inhibitor (AChEI) that has been widely recognized for improving cerebral blood flow and modulating inflammatory responses in ischemic stroke (IS). Therefore, the applicant will conduct an internationally compliant, randomized controlled clinical study with routine treatment to evaluate the efficacy of galantamine in the treatment of acute cerebral infarction. This project will conduct a comprehensive assessment of the drug's efficacy from multiple aspects, including improvements in stroke-related outcomes, Traditional Chinese Medicine (TCM) syndrome manifestations, cognitive function, cerebral blood flow, and inflammatory factors.
