title: Effects of indeloxazine hydrochloride (YM-08054) on anoxia.
abstract: Effects of indeloxazine hydrochloride [(+/-)-2-[(inden-7-yloxy)methyl]morpholine hydrochloride, YM-08054] on anoxia were examined. Indeloxazine significantly prolonged survival time of mice subjected to anoxia and improved anoxia-induced impairment of the passive and active avoidance learnings in rats. Indeloxazine at doses inducing anti-anoxic actions showed no effect on cerebral blood flow in cats and pentobarbital sleeping time in mice. Therefore, anti-anoxic actions of indeloxazine are not attributable to cerebral vasodilative or central depressant activities. Calcium hopantenate (cerebral metabolic enhancer) also showed anti-anoxic actions, whereas neither viloxazine, amitriptyline (antidepressant) nor dihydroergotoxine (cerebral vasodilator) showed any effect on anoxia. These results suggest that indeloxazine possesses anti-anoxic activities similar to calcium hopantenate. The mode of anti-anoxic actions of indeloxazine is also discussed.
