    Differential effects of haloperidol, clozapine, and fluperlapine on tuberoinfundibular dopamine neurons and prolactin secretion in the rat (1987)

    Notes: Summary Two atypical neuroleptic agents, clozapine and fluperlapine, produced rapid elevations in plasma PRL concentrations that were similar in magnitude to those produced by haloperidol. However, the PRL response to clozapine or fluperlapine was of much shorter duration than that elicited by haloperidol. Clozapine, but neither fluperlapine nor haloperidol, produced a rapid increase in the activity of tuberoinfundibular dopamine (TIDA) neurons, as evidenced by an enhanced accumulation of dihydroxyphenylalanine (DOPA) in the median eminence after the inhibition of DOPA decarboxylase. The clozapine-induced increase in DOPA accumulation was evident within 30 minutes after its administration and persisted for at least 4 hours. The clozapine-induced increase in the activity of TIDA neurons may account, in part, for the abbreviated PRL response to this neuroleptic. In addition, ability to produce a short-lived increase in PRL secretion in the rat appears to be common to the atypicl neuroleptic drugs.

    A prospective study of clozapine in treatment-resistant schizophrenic patients (1989)

    Notes: Abstract Preliminary results of a non-blinded prospective study of the effect of clozapine on symptomatology and social function in 51 treatment-resistant schizophrenic patients are reported. The mean duration of treatment at the time of this report was 10.3±8.1 months, median 7.6 months. Overall, 3/51 patients (60.8%) showed at least a 20% decrease in total BPRS, a criterion of improvement in the study of Kane et al. (1988). Four of 51 (7.8%) had at least a 50% decrease in total BPRS. Improvements in both positive and negative symptoms were noted. Marked improvements in social function were noted within the first 6 months of treatment. Improvement was first noted at all time points, with only 45.2% of improvers being identified after 6 weeks of treatment. These results suggest a 6–12-month trial may be desirable before deciding to discontinue clozapine because of insufficient response. Higher total Brief Psychiatric Rating Scale (BPRS) score and higher ratings on the Paranoid Disturbance subscales of the BPRS were factors which discriminated clozapine responders from non-responders.

    Activity of tuberoinfundibular dopaminergic neurons and concentrations of serum prolactin in the rat following lithium administration (1988)

    Notes: Abstract Maintenance of rats on a lithium-containing diet for 3–21 days resulted in a suppression of prolactin (PRL) secretion in vivo and in vitro. Lithium treatment also resulted in an increase in the activity of tuberoinfundibular dopaminergic neurons, as evidenced by an increased accumulation of dihydroxyphenylalanine (DOPA) in the median eminence after inhibition of DOPA decarboxylase and an increased concentration of dopamine in the anterior pituitary gland. The accumulation of DOPA in the neurointer-mediate lobe of the pituitary gland, the prefrontal cortex, the striatum and the nucleus accumbens was also enhanced by lithium treatment. It is concluded that lithium treatment enhances the synthesis of dopamine in many brain regions and that an increased activity of tuberoinfundibular dopaminergic neurons results in an enhanced inhibitory control of PRL secretion.
