The same medication used to preserve life by reversingopioid overdosesmay also benefit nonopioid users . In a new study done in rats , the medicine , called Narcan , was shown to help the mentality to recover from a stroke .
Researchers found that when manly rats were treated for one week with naloxone after having an ischemic stroke , they had an improved recuperation , compared with rats who did not obtain naloxone . ( Anischemic strokeoccurs when rakehell flow to the Einstein is disrupt , usually because of a blood coagulum , which divest the brain of oxygen and damages nerve cubicle in the sphere . ) [ Strange Stroke Stories : Ebola , Hickeys and Other Weird Causes ]
Naloxone is used to treat opioid overdoses.
Because the study was done in rats , more research is needed to confirm the findings in people . However , naloxonemight play a function in stroke convalescence because the drug has anti - rabble-rousing properties and can cut the activity of the microglia , which are the basal immune cells of the learning ability , according to the study findings , issue today ( April 16 ) in the journaleNeuro .
Previous enquiry has shown that Narcan affects themicroglia , which are very active contributors to the inflammation that occurs in the brain following a separatrix , said study co - generator Brandon Harvey , a researcher at the National Institute on Drug Abuse in Baltimore . So , in this study , the researchers wanted to see whether founder naloxone after a stroke could decrease the activity of the mentality ’s immune cells and reduce the associated inflaming , leading to improved recovery from the virgule , he said .
Improved stroke recovery
In the Modern subject , the researcher give 65 manlike lowlife naloxone twice a day through the nose at a dose considered to be safe in humans . ( Narcan is often given as a nasal atomiser to overturn an overdose , concord to the study . ) The cogitation record that the drug was most efficacious when treatment was started within 16 to 36 hours after a CVA and lasted for seven days .
The findings showed that when naloxone was given after a shot , during a period whenimmune - cell activityin the head was peaking , it had beneficial consequence on recovery , said study co - writer Mikko Airavaara , master investigator at the Institute of Biotechnology at the University of Helsinki in Finland . ( Immune cells in the lowlife ' encephalon were active as early as two days after a stroke and reached their meridian activity seven days after a stroke , according to the finding . )
Airavaara said that naloxone works reducinginflammation in the brainand reducing the loss of nerve cellular telephone , which can better the encephalon ’s ability to recuperate after a stroke .
Naloxone is used to treat opioid overdoses.
These findings are important because there is no drug treatment now that serve the brain recover after a stroke , Airavaara severalise Live Science . So , evolve a drug therapy that could promote recovery for the 10 million people worldwide who have accident each twelvemonth would be groundbreaking , he said .
Indeed , because naloxone has been used to do by opioid overdoses for nearly 50 years , the idea of repurposing the drug for stroke is intriguing , Harvey said .
What about people?
Still , more enquiry is needed in animals before Narcan is studied in people who have had a stroke . [ 7 thing That May Raise Your risk of infection of Stroke ]
It would be crucial to demonstrate that the drug ’s good effects would knead not only in male stinkpot but in distaff rats as well , Harvey told Live Science .
The current study was able to establish an effective saving method for the drug — through the nozzle , which is one of the methods already used toreverse opioid overdose — and a suggested dosing pattern ( when to give the drug ) to maybe translate these findings into clinical practice session in the future , Harvey said .
Daniel Lackland , a professor of epidemiology in the clinical neurology section at the Medical University of South Carolina in Charleston , who was not involved in the new inquiry , say that there is a need to identify other treatments for slash recovery . Currently , reclamation includes physical- , occupational- and lecture - therapy political platform ; however , treatments that aim physiological changes in the Einstein are lack , he say .
In improver , recovering from a stroke has not had the same success rates as recovering fromheart disease , said Lackland , who is a representative for the American Stroke Association .
This written report explored the possibility that a new drug may contribute to stroke recovery , and this drug appears to have some benefits in animals , Lackland told Live Science . Though the finding need to be replicate in additional animate being study , these results give hope for the future of potential trials in humans , he say .
