Abstract

Traumatic brain injuries (TBIs) are among the most important clinical and research areas in neurosurgery, owing to their devastating effects and high prevalence. Over the last few decades, there has been increasing research on the complex pathophysiology of TBI and secondary injuries following TBI. A growing body of evidence has shown that the renin-angiotensin system (RAS), a well-known cardiovascular regulatory pathway, plays a role in TBI pathophysiology. Acknowledging these complex and poorly understood pathways and their role in TBI could help design new clinical trials involving drugs that alter the RAS network, most notably angiotensin receptor blockers and angiotensin-converting enzyme inhibitors. This study aimed to briefly review the molecular, animal, and human studies on these drugs in TBI and provide a clear vision for researchers to fill knowledge gaps in the future. © 2023 Korean Neurotraumatology Society.
