Ciproxifan is an extremely potenthistamine H3inverse agonist/antagonist.

The histamine H3 receptor is an inhibitory autoreceptor located on histaminergic nerve terminals, and is believed to be involved in modulating the release of histamine in the brain. Histamine has an excitatory effect in the brain via H1 receptors in thecerebral cortex, and so drugs such as ciproxifan which block the H3 receptor and consequently allow more histamine to be released have an alertness-promoting effect.[1][2][3]

Ciproxifan produces wakefulness and attentiveness in animal studies, and produced cognitive enhancing effects without prominent stimulant effects at relatively low levels of receptor occupancy, and pronounced wakefulness at higher doses.[4] It has therefore been proposed as a potential treatment for sleep disorders such asnarcolepsy and to improvevigilance in old age, particularly in the treatment of conditions such asAlzheimer's disease.[5][6] It also potentiated the effects of antipsychotic drugs, and has been suggested as an adjuvant treatment for schizophrenia.[7]
