Research from the University of Leicester could provide a new lease of life to stroke victims.
The research confirms the safety of Lisinopril, a drug used to lower blood pressure.
Leicester is now trialling the drug with stroke patients.
Dr David Eveson, of the University of Leicester, said: "High blood pressure is common immediately after a stroke.
Stroke patients with high blood pressure tend to have a worse outcome than those with normal blood pressure and therefore it may be helpful to lower blood pressure immediately after a stroke."
Lisinopril has been shown to lower blood pressure while preserving the flow of blood to the brain, which is important in the aftermath of a stroke.
Dr Eveson continued: "Stroke is the second commonest cuase of death in the UK ad the commonest cause of adult disability. It is imperative that we strive to discover new treatments for stroke to reduce the substantial impact of the disease."
He said the study will pave the way for larger studies to fully establish the benefit of the drug.
