A column-switching high-performance liquid chromatographic method with fluorescence detection was developed for the simultaneous determination of four benzamide-type anti-psychotic drugs: sulpiride, tiapride, sultopride and metoclopramide in human serum. In this method, a TSKgel Super-ODS column was used as an analytical column, and a TSKgel G 2000SW was prepared as a pretreatment column. Under...

Background: Sulpiride is a substituted benzamide derivative and a selective dopamine D2 antagonist with antipsychotic and antidepressant activity. Sulpiride is effective in the treatment of acute and chronic schizophrenia.Sexual function is multifaceted and is affected in many ways by schizophrenia and the antipsychotic drugs used in its treatment . Sulpiride are associated with elevation of pr...

PURPOSE Previous studies have demonstrated sulpiride to be significantly more effective than haloperidol, risperidone and olanzapine in schizophrenic treatment; however, only limited information is available on the potential risks associated with sulpiride treatment. This study attempts to provide information on the potential risks of sulpiride treatment of schizophrenia, especially with regard...

We examined the effects of minaprine and sulpiride injected into the medial amygdaloid nucleus on the duration of immobility in rats forced to swim. Minaprine (50 micrograms/microliter) significantly reduced the duration of immobility, while sulpiride (50 micrograms/microliters) remarkedly enhanced it. These results suggest that the medial amygdaloid nucleus might be involved in the suppressive...

Recent studies have demonstrated that psychotropic drugs such as reserpine and chlorpromazine cause a significant increase in plasma human prolactin (hPRL) levels, frequently inducing galactorrhea (Frantz et al., 1972). Chlorpromazine is now commonly used as a means of stimulating hPRL secretion in man (Friesen et al., 1972; Turkington, 1972). Borenstein et al. (1968) first reported that galact...

The effects of the benzamide derivatives, (-)-sulpiride, sultopride and nemonapride, on spontaneous and electrically evoked dopamine (DA) release from striatal slices of rats were investigated. Nemonapride at concentrations of 100 nM or higher caused a dose-dependent increase in spontaneous DA release from the slices. (-)-Sulpiride and sultopride had little effect on spontaneous DA release. The...

In order to study the mode of action of TRH and sulpiride in man, we administered TRH (500 micrograms, iv) and sulpiride (DA D2 receptor antagonist, 100 mg, im) simultaneously to 6 normal females (20-21 yr). Normal females showed significantly greater PRL increments and AUC in response to the combined administration compared to a single administration of each agent (P < 0.05-0.01), while the in...

Effects of bromocriptine and sulpiride were observed on encoding and retrieval of spatial memory in Wistar rats using Hebb-Williams complex maze. Rat was placed in entry chamber and allowed to reach reward chamber. Ten trials were given each day per rat for 3 consecutive days. Within-day encoding score indicative of learning and between-day retrieval score indicative of memory were calculated. ...

Background: As previous studies show, several effects of morphine are induced by the dopaminergic system. Sulpiride is a dopamine D2 receptor (DAD2) antagonist widely used in clinics to treat DArelated disorders. DAD2 receptors are abundant at hippocampal cornu ammonis (CA1). Objectives: This study aimed to investigate the possible interaction of morphine and sulpiride on DA synapses in CA1...
