| Bioactivity | Dexmedetomidine hydrochloride ((+)-Medetomidine hydrochloride) is a potent, selective and orally active agonist of α2-adrenoceptor, with a Ki of 1.08 nM. Dexmedetomidine hydrochloride shows 1620-fold selectivity against α1-adrenoceptor. Dexmedetomidine hydrochloride exhibits anxiolysis, sedation, and modest analgesia effects[1][2][3]. |
| Invitro | Medetomidine has high selectivity for α2 adrenoceptors (Ki=1.08 nM) over α1 adrenoceptors (Ki=1750 nM) in rat brain membranes as measured by the displacement of [3H]clonidine[1].Medetomidine (0.1-100 nM) inhibits the twitch response in field-stimulated mouse vas deferens, with a pD2 of 9.0[1]. |
| In Vivo | Medetomidine (10-100 μg/kg; i.v. at 5-min intervals) produces a dose-dependent pupillary dilatation in pentobarbitone-anaesthetized rats[1]. Animal Model: |
