Perforating Artery Infarction

The goal of this clinical trial is to learn if Y-6 sublingual tablets work to improve functional outcomes in patients with acute perforating artery infarction. It will also learn about the safety of Y-6 sublingual tablets. The main questions it aims to answer are: Does Y-6 sublingual tablets increase the proportion of participants who achieve a modified Rankin Scale (mRS) score of 0-1 at Day 90 after treatment? What medical problems do participants have when taking Y-6 sublingual tablets? Researchers will compare different doses of Y-6 sublingual tablets and placebo to evaluate the effectiveness and safety of Y-6 sublingual tablets in patients with acute perforating artery infarction. Participants will: Take Y-6 sublingual tablets or placebo according to the assigned treatment regimen. Visit the clinic for assessments of neurological function, functional outcomes, and safety during the study period. Complete clinical assessments, including neurological examinations, laboratory tests, and other safety evaluations. Be followed for functional outcomes and safety events after treatment.
