Ipsapirone inhibits induced by 8-OH-DPAT and 5-methoxydimethyltryptamine (agonists of 5-HT1A receptors) behavioural effects (flat body posture and forepaw treading) in normal and reserpinized rats[1].
Ipsapirone (2.5-80 mg/kg), given alone to rats induces a slight flattening of body posture (~ 1 point at the highest dose) and a mild hind limb abduction observed at doses 2.5-80 mg/kg. Ipsapirone given alone at low doses (2.5-10 mg/kg i.p.) does not significantly change the body temperature in rats and mice, but decreased it in both those species at high doses (35 mg/kg i.p.) by ca. 2-2.5℃[1].
| Animal Model: | Male Albino-Swiss mice (18-24 g) and male Wistar rats (160-200 g)[1].
|
| Dosage: | 5 and 10 mg/kg. |
| Administration: | IP 30 min before 8-OH-DPAT and 5-MeODMT injections. |
| Result: | Behavioural responses (flat body posture, forepaw treading) to 8-OH-DPAT (5 mg/kg s.c.) in rats were antagonized by Ipsapirone (5 and 10 mg/kg i.p.). |
