Tranexamic acid treatment for head injury
Tranexamic acid reduces clot breakdown the investigators hypothesised that this drug could reduce bleeding into the brain and therefore improve patients outcomes.
London: Tranexamic acid has the potential to prevent people dying from head injuries, a new research has suggested.
The CRASH-2 Intracranial Bleeding Study highlights the potential of the cheap, off-patent drug to help people suffering from brain trauma.
According to the collaborators – led by the London School of Hygiene and Tropical Medicine - the results provide strong grounds to test the effect of this treatment in a larger and definitive study.
The forthcoming CRASH-3 trial will determine reliably the effectiveness of tranexamic acid in patients with head injury.
One of the frequent complications occurring after head injury is bleeding into the head. Usually this bleeding progresses in the first hours after the injury and produces more brain damage. Because tranexamic acid reduces clot breakdown the investigators hypothesised that this drug could reduce bleeding into the brain and therefore improve patients`` outcomes.
The CRASH-2 Intracranial Bleeding Study was the first to evaluate the effect of tranexamic acid on head injury patients. The results showed that patients who receive tranexamic acid were less likely to have bleeding progression, they survive more and with less disability.
Dr Pablo Perel, who is based in the Clinical Trials Unit at LSHTM, said: "Although the results are not definitive they provide hope about the potential effectiveness of this simple drug for head injury patients. If such an inexpensive and widely practicable treatment were found to improve patient outcomes after head injury this would have major implications for clinical care."
The study has been published online by the BMJ.
