Effects of selective activation of the 5-HT1B receptor with CP-94,253 on sleep and wakefulness in the rat.

Author information

Department of Pharmacology and Therapeutics, Clinics Hospital, Montevideo, Uruguay.


The effects of the 5-HT1B receptor agonist CP-94,253 were compared with those of the mixed beta-adrenoceptor and 5-HT1A/B receptor antagonist (+/-)pindolol in rats implanted for chronic sleep recordings. CP-94,253 (5.0-10.0 mg/kg) significantly increased waking and reduced slow wave sleep (SWS) and REM sleep (REMS). At 2.0-4.0 mg/kg (+/-)pindolol reduced REMS. Pretreatment with (+/-)pindolol (2.0-4.0 mg/kg) reversed the effect of CP-94,253 on waking and SWS, while REMS remained suppressed. It is suggested that the 5-HT1B receptor together with other 5-HT receptor subtypes may have a direct regulatory action on sleep and waking in the rat.
