“…Fenfluramine produced no statistically significant effects on BPRS (Brief Psychiatric Rating Scale) subscales, although there were tendencies towards an improvement in activation and global BPRS ratings and a worsening in BPRS negative symptoms. A report on the clinical outcome of this study (Marshall et al 1989) showed that fenfluramine had a significant adverse effect on psychopathology. There was, however, evidence of some improvement in both positive (BPRS) and negative [BPRS, SANS (Adreason's Scale for the Assessment of Negative Symptoms)] symptoms in 2 patients on the active drug.…”

“…Since all patients showed clinical deterioration after the administration of fenfluramine (Marshall et al 1989), it was important to establish whether adverse changes in psychopathology might be related to fenfluramine-induced changes in the plasma concentrations of neuroleptic drugs or key metabolites. Thus ANOV A and the Student-Neuman-Keuls range test were used to detect significant differences in neuroleptic/metabolite concentrations before (group I), during (group 2) and after (group 3) fenfluramine treatment.…”

“…The exact mechanisms whereby adjunctive SSRIs improve the symptoms of treatment-refractory schizophrenic patients are unknown. In preliminary findings, fenfluramine, a serotonin-releasing agent improved negative symptoms, although this is not a consistent finding (Stahl et al, 1985;Alphs et al, 1989;Marshall et al, 1989). On the other hand, among direct serotonin antagonists both the non-selective agent, cyproheptadine (Silver et al, 1989) and the selective serotonin-2/1C antagonist, ritanserin (Duinkerke et al, 1993) have been associated with therapeutic effects.…”

“…Επιπλέον, πολλά από τα νεότερα άτυπα αντιψυχωτικά φάρμακα (ρισπεριδόνη, ολανζαπίνη) έχουν ισχυρές αντισεροτονινεργικές δράσεις σε αρκετούς από τους 5ΗΤ υποδοχείς (DaSilva Alves et al, 2008). Η υπόθεση ντοπαμίνης-σεροτονίνης έχει εξετασθεί σε πολλές μεταθανάτιες μελέτες στον εγκεφαλικό ιστό ασθενών με σχιζοφρένεια (Whitaker et al, 1981, Mita et al, 1986, Hashimoto et al, 1991 καθώς και σε προκλητές φαρμακολογικές μελέτες (Laferrere και Wurtman, 1989, Marshall et al, 1989, Krystal et al, 1993. Ωστόσο, τα αποτελέσματα παραμένουν ασαφή.…”
