(S)-(−)-Sulpiride was used to study the effect of dopamine D2 receptor function on activation of KCNQ potassium channels10 and on depression-like behavior in ovariectomized female rats.11


5, 10 g in poly bottle

Biochem/physiol Actions

(S)-(−)-Sulpiride or Levosulpiride blocks the inhibitory enteric D2 receptors (neuronal and muscular). It has prokinetic activity and is effective in the treatment of functional dyspepsia and gastroparesis in insulin-dependent diabetes mellitus patients.7,8 Since dopamine controls human sexual function, (S)-(−)-Sulpiride is reportedly effective in treatment of erectile dysfunctions.9
D2 dopamine receptor antagonist; antipsychotic.

Somatodendritic dopamine (DA) release from midbrain DA neurons activates D2 autoreceptors on these cells to regulate their activity. However, the source of autoregulatory DA remains controversial. Here, we test the hypothesis that D2 autoreceptors on a given DA neuron in

The dopamine D2 receptor antagonist levosulpiride is a substituted benzamide derivative, whose gastrokinetic properties are exploited clinically for the management of functional dyspepsia. However, for other benzamide derivatives, such as cisapride and mosapride, agonism towards serotonin 5-HT4 receptors is considered
