Neuroprotective Drugs

Cardiac arrest is one of the critical illnesses that is directly life-threatening, and patients who survive cardiac arrest develop severe neurological deficits or even die. The effectiveness of drugs to improve neurological function in resuscitated brain-injured patients has been a focus of research in the field of resuscitation. Butanephthalein has an ameliorating effect on the damage of central nervous function in patients with acute ischemic stroke, and can promote the improvement of patients' neurological deficits. On this basis, the present study was designed as a multicenter, prospective randomized controlled experiment, with internationally accepted methods for assessing near-term and long-term neurological function, to determine the effectiveness of butalbital in improving neurological function after cardiac arrest, with the aim of searching for new methods and ideas to improve neurological function and prognosis after cardiac arrest.

Butylphthalide (NBP) is a neuroprotective medication capable of ameliorating neurological dysfunction induced by ischemia, hypoxia, and reperfusion injury in the brain. However, evidence regarding the improvement of neurological function prognosis in patients with return of spontaneous circulation (ROSC) after cardiac arrest (CA) by NBP is limited. This study aims to evaluate the safety and efficacy of NBP treatment in improving the neurological function prognosis of patients with ROSC after CA.The study will be a single-center, randomized, double-blind, placebo-controlled trial. The sample size is estimated to be 100 patients. Eligible patients will be randomly allocated in a 1:1 ratio to receive either NBP or placebo treatment daily for a duration of 14 days. The initial administration of NBP or placebo treatment will commence within 6 hours after ROSC following CA. The primary outcome is the proportion of patients with Cerebral Performance Category (CPC) scores of 1-2 at 90 days after randomization in each group. The primary safety outcome is the percentage of severe adverse events occurring during the 14-day treatment period. This trial will determine the efficacy of NBP in providing neuroprotective effects for patients with ROSC after CA.

The goal of this clinical trial is to learn if semaglutide works to treat acute ischemic stroke (AIS). It will also learn about the safety of semaglutide in AIS. The main question it aims to answer is: Does semaglutide improve the 90-days functional outcome in participants with acute large vessel occlusion who receive the endovascular treatment (EVT)? Researchers will compare semaglutide injection to non-injection to see if semaglutide works to improve the functional outcome in participants with EVT. Participants will: * Receive 0.5mg semaglutide injection before (Day 0) and 1 week (Day 7) after EVT , or EVT alone. * Have additional blood test before and after EVT. * Receive neurological assessment before EVT, Day 1, Day 3, Day 5-7 after EVT or on hospital discharge (whichever earlier), Day 90±14 after EVT. Audio or video of the assessment may be recorded if possible. * Receive brain CT + CT angiogram + CT perfusion and MRI after EVT, where the CT scan may be repetitive.
