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...

due to the prolonged exposure (6 days). hG.H. secretion from another somatotrophic adenoma (data not shown) was inhibited 76-8±2-4% within 24 h by bromocriptine, remained inhibited for 2 days, and subsequently increased in three of four cultures in 24 h when bromocriptine was withdrawn. This change just failed to achieve statistical significance. Further reduction in exposure-time and do...

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...

OBJECTIVE It is well known that bromocriptine has a suppressive effect on the prolactin release in hyperprolactinemic patients. But it also has some adverse effects. The new, long-acting dopaminergic drug, cabergoline, has been reported to be an effective agent in these patients. However, there are relatively few reports comparing the beneficial and adverse effects of these drugs in the treatme...

BACKGROUND Cabergoline is a long-acting dopamine-agonist drug that suppresses prolactin secretion and restores gonadal function in women with hyperprolactinemic amenorrhea. We designed a study to compare its safety and efficacy with those of bromocriptine, which has been the standard therapy. METHODS A total of 459 women with hyperprolactinemic amenorrhea were treated with either cabergoline ...

Pleurisy of initially unknown origin was found in a patient who was treated with bromocriptine for Parkinson's disease for 6 years. At presentation, bilateral pleural thickening existed that caused severe restriction of pulmonary function. There were an elevated erythrocyte sedimentation rate, polyclonal hypergammaglobulinaemia, increased levels of acute phase proteins and anaemia. After withdr...

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...
