General description

Atipamezole has an imidazole structure and gets localized in the central nervous system on administration.[1]

Application

Atipamezole has been used as a α2-adrenoceptor antagonist in mesencephalic trigeminal nucleus (MTN) neurons,[2] CD4+ T-lymphocyte[3] and human embryonic kidney (HEK293) membrane preparation.[4]

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.[1] Atipamezole shows no affinity towards muscarinic[1] and dopamine or neurotransmitter receptors.[5] Atipamezole when used along with morphine elicits antinociceptive effects.[6]
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 a selective α2 adrenergic blocker; neutral antagonist
