Biochem/physiol Actions

Atipamezole is a selective α2 adrenergic blocker; neutral antagonist
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.

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.

Opioid analgesics are effective in the treatment of chronic pain, but they have serious adverse effects such as development of tolerance and dependence. Adrenergic α(2) agonists and μ-opioid receptor agonists show synergistic potentiation and cross-tolerance in spinal analgesia, whereas α(2)-adrenergic
