Novel Pharmacological Approaches for Neuroprotection in Acute Stroke

Abstract

Acute stroke remains a leading cause of mortality and long-term disability worldwide, necessitating urgent advancements in neuroprotective strategies to mitigate brain damage and improve patient outcomes. Despite progress in reperfusion therapies, the translation of preclinical neuroprotective agents to clinical success has been limited by challenges such as narrow therapeutic windows, heterogeneity in stroke pathology, and safety concerns. This review critically examines the current landscape of neuroprotection in acute stroke, highlighting emerging pharmacological approaches and the barriers to their clinical implementation. The review explores novel pharmacological strategies, including targeted molecular therapies like nerinetide and repurposed drugs such as glibenclamide, which show promise in addressing excitotoxicity and cerebral edema. It also discusses innovative delivery methods, such as intranasal administration and nanotechnology-based systems, designed to enhance drug bioavailability and bypass the blood-brain barrier (BBB). Insights from clinical trials, including the ESCAPE-NA1 and EXTENDIA TNK studies, underscore the potential of combining neuroprotection with reperfusion therapies. Additionally, the review evaluates non-pharmacological adjuncts like transcranial magnetic stimulation (TMS) and hypothermic neuroprotection, which may complement traditional drug treatments. The integration of multi-target therapeutics and temporal targeting approaches is emphasized as a means to address the dynamic pathophysiology of stroke. Finally, the review highlights the role of advanced technologies, such as artificial intelligence and systems biology, in accelerating the development of next-generation neuroprotective agents. Future research should focus on refining preclinical models to better mimic human stroke conditions and optimizing clinical trial designs to validate the efficacy of emerging therapies. The exploration of holistic approaches targeting the neurovascular unit and the combination of neuroprotection with rehabilitation techniques represents a promising frontier. By fostering interdisciplinary collaboration and leveraging cutting-edge innovations, the field can overcome existing challenges and realize the potential of neuroprotection as a cornerstone of comprehensive stroke care.
