The selective 5-HT1A receptor ligand ipsapirone (IPS) induces hypothermia in humans. To explore 5-HT1A receptor-mediated thermoregulation in depression, 24 subjects (12 patients with unipolar depression and 12 individually matched controls) received 0.3 mg/kg IPS or placebo in random order. Compared with controls, the depressed patients exhibited(More)
Clinical studies suggest that 5-HT1A receptor function may be blunted in depression, while 5-HT1A agonists may possess antidepressant activity. Preclinical findings implicate changes in 5-HT1A receptor sensitivity in the mechanism of antidepressant action. The hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis in depression could be related to(More)
Pharmacokinetics and bioavailability of benperidol were determined in 13 schizophrenic patients after acute administration of 6 mg benperidol as an intravenous (i.v.) bolus injection, orally as liquid, and orally as tablets using a partially randomized cross-over design. Drug plasma levels were determined by high performance liquid chromatography with(More)
Tienocarbine (1,9-dimethyl-7,8,9,10-tetrahydrothieno[3,2-e] pyrido[4,3-b] indole lactate) in oral doses of 10 mg X kg-1 lowers dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) in the striata of rats without influencing contents of biogenic amines; this points to a reduced dopamine (DA) turnover. This effect is still present after 28 days of(More)
