Dexmedetomidine is a potent agonist of a2 adrenergic and very specific experience of receptor-binding selectivity has a t ratio Ratio A2/A1 of 1600, or four hours Ago than clonidine. It strongly activates all three subtypes of a2-adrenergic receptor, all sensitive to the pertussis toxin Gi / o-coupled receptors are linked. The best known effects of dexmedetomidine in the brain is a AB1010 pr Synaptic inhibition of noradrenaline release and cell firing in noradrenergic neurons, but only a small fraction of a2 adrenergic receptors appears to be pr Synaptic. Consequently, several pharmacological effects of dexmedetomidine independent Ngig by inhibiting the release of norepinephrine.

In addition to the effects of hypnotics / sedatives and analgesics, low concentrations of dexmedetomidine, with one exception, have been found repeatedly to neuroprotective properties in experimental cerebral ish Excitotoxic neuronal chemistry and Sch have Apology.
The mechanism of neuroprotection is not known, but the neuroprotective effect of dexmedetomidine can be detected even under conditions where it does not reduce ish Chemistry-induced increase in brain norepinephrine. Target cells in the CNS adrenergic a2 job intersection go Ren astrocytes, which will in particular focus on the expression of subtype A2A / D-adrenoceptors. We previously reported that dexmedetomidine in the concentration range 25 nM, 100 causes phosphorylation of ERK1 and ERK2 in cultured mouse astrocytes, phosphorylation of ERK1 / 2 occurred rapidly, reached at 20 min and decreased 40 min after stimulation. Based on the inhibition of phosphorylation by tyrphostin AG 1478, an inhibitor of tyrosine kinase and by heparin, an antagonist of epidermal growth factor heparin-binding, we suggested that this effect is the result of the receptor transactivation is epidermal growth factor.
