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: Male CD-COBS rats injected with 1 mg/kg haloperidol[1] Dosage: 0.16 mg/kg, 0.31 mg/kg, 0.63 mg/kg, 1.25 mg/kg, 2.5 mg/kg, and 5.0 mg/kg Administration: Subcutaneous injection; for 1 hour Result: Potently reversed haloperidol-induced catalepsy with an ED50 of 0.25 mg/kg.
