| Bioactivity | Idazoxan hydrochloride (RX 781094 hydrochloride) is an α2-adrenoceptor antagonist and is also a imidazoline receptors (IRs) antagonist competitively antagonized the centrally induced hypotensive effect of imidazoline-like drugs (IMs). Idazoxan hydrochloride also improves motor symptoms in Parkinson’s disease, L-DOPA-induced dyskinesias, and experimental Parkinsonism[1][2]. |
| In Vivo | Idazoxan (0.16-5 mg/kg; subcutaneous injection; for 1 hour; male CD-COBS rats) treatment potently reverses haloperidol-induced catalepsy with an ED50 of 0.25 mg/kg. Idazoxan (0.3 and 2.5 mg/kg) has no effect on extracellular DA and do not modify the rise of extracellular DA induced by haloperidol[1]. Animal Model: |
