General description

Atipamezole has an imidazole structure and gets localized in the central nervous system on administration.

Application

Atipamezole has been used as a α2-adrenoceptor antagonist in mesencephalic trigeminal nucleus (MTN) neurons, CD4+ T-lymphocyte and human embryonic kidney (HEK293) membrane preparation.

Biochem/physiol Actions

Atipamezole elicits affinity towards adrenoreceptor subtypes namely α2A, α2B and α2C. High levels of atipamezole impairs cognitive functions. It also reverses the adrenoreceptor agonist functionalities. Atipamezole shows no affinity towards muscarinic and dopamine or neurotransmitter receptors. Atipamezole when used along with morphine elicits antinociceptive effects.
Atipamezole is a selective α2 adrenergic blocker. Atipamezole is more potent than yohimbine; it is very selective for α2 adrenergic vs α1 sites, but not selelctive for α2 subtypes.

Atipamezole is an alpha2-adrenoceptor antagonist with an imidazole structure. Receptor binding studies indicate that its affinity for alpha2-adrenoceptors and its alpha2/alpha1 selectivity ratio are considerably higher than those of yohimbine, the prototype alpha2-adrenoceptor antagonist. Atipamezole is not selective for subtypes
