體內(nèi)研究
Orexin A human, rat, mouse (3-30 mg/kg; i.v.; 5 min pre-test) significantly increases the latency to response at 10 and 30 mg/kg i.v. when given 5 min pre-test from 24.8±2.0 s in vehicle-treated mice to 35.0±3.7 s and 45.7±4.5 s, respectively.
Orexin A human, rat, mouse (3, 10 and 30 mg/kg; i.v.) was given immediately before phenylp-quinone (PPQ) and increases the latency to the first PPQ-induced constriction from 357.4±35.2 s in vehicle-treated mice to 500.3±31.2 s at 10 mg/kg and 594.5±5.5 s at 30 mg/kg.
| Animal Model: | Female mice (mouse carrageenan-induced thermal hyperalgesia test) |
| Dosage: | 3, 10 and 30 mg/kg |
| Administration: | i.v.; 5 min pre-test |
| Result: | Significantly increased the latency to response at 10 and 30 mg/kg. |
