Abstract The administration of methamphetamine (METH, 10 mg/kg, i.p.) to male ICR mice induced stereotyped behavior consisting of nail and/or wood chip biting (86.0%), continuous sniffing (12.0%), head bobbing (1.1%), and circling (1.0%) during the observation period of 1 h. Pretreatment of the mice with metoprine (2, 10, and 20 mg/kg, i.p.), a selective inhibitor of histamine N -methyltransferase (HMT), which metabolizes histamine in the brain, significantly increased and decreased METH-induced continuous sniffing (20.5, 51.3, and 80.3%) and nail and/or wood chip biting (77.4, 45.3, and 14.2%), respectively, in a dose-dependent manner. The hypothalamic contents of histamine and its metabolite Nτ -methylhistamine were significantly increased and decreased by metoprine (10 mg/kg, i.p.), respectively. The metoprine action on METH-induced behavior was completely abolished by pyrilamine (10 and 20 mg/kg) and ketotifen (10 mg/kg), selective, centrally acting histamine H1 receptor antagonists, but not by fexofenadine (20 mg/kg), zolantidine (10 mg/kg) and thioperamide (10 mg/kg), a peripherally acting histamine H1 receptor antagonist and a selective, brain-penetrating antagonist for histamine H2 and H3 receptors, respectively. The metoprine action was mimicked by SKF 91488 (100 μg/animal, i.c.v.), another HMT inhibitor, and the action of SKF 91488 was also blocked by pyrilamine. The frequency of the expression of METH-induced total stereotypic patterns was unchanged after metoprine pretreatment. Mice pretreated with metoprine displayed no anxiety-like behavior in the elevated plus maze test. These results suggest that brain histamine, increased by agents such as metoprine and SKF 91488, binds to histamine H1 receptors in the brain, resulting in the modulation of dopaminergic transmission associated with stereotyped behavioral patterns induced by METH.
