Evaluation of delayed treatment of focal cerebral ischemia with three selective k-opioid agonists in cats
Ischemic Attack, Transient
Compounds that act at the kappa subclass of opiate receptors are effective in increasing survival, improving neurological function, and decreasing tissue damage and edema in a cat model of focal cerebral ischemia. The current study provides support for the benefits of treatment of acute cerebrovascular ischemia with kappa-opioid agonists. The agents may prove to be of superior clinical utility because of efficacy even when administered 6 hours after the onset of stroke.
