General description
Atipamezole has an imidazole structure and gets localized in the central nervous system on administration.[1]
Application
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.[4] Atipamezole when used along with morphine elicits antinociceptive effects.[5]
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

The C-terminal half of the alpha 2C-adrenoceptor determines the receptor's membrane expression level and drug selectivity

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

Anesthesia and analgesia, 112(6), 1500-1503 (2011-05-06)
Ultralow-dose opioid antagonists prolong opioid antinociception and block tolerance. In this study we determined whether low doses of the α-2 adrenergic receptor (A2-R) antagonist, atipamezole, similarly influenced A2-R-induced antinociception and tolerance. In rats, intrathecal norepinephrine (NE) or clonidine in combination
