US combat soldiers in Iraq who received a shot of morphine within an hour of being wounded were less likely to develop post-traumatic stress disorder, according to researchers. Researchers reporting in the New England Journal of Medicine say taking the powerful pain killer is no guarantee of preventing PTSD.
But the discovery may help doctors find a better way to prevent this disorder. What they are not sure of just yet is whether the effect is from pain reduction or something the morphine actually does to memory.
Researchers are planning to look at the effect of other opiates and anti-anxiety drugs to see if they work as well.
