Background:

Amisulpride hydrochloride is a dopamine D2/D3 receptor antagonist with Kis of 2.8 and 3.2 nM for human dopamine D2 and D3, respectively. Ki: 2.8 nM (D2 receptor), 3.2 nM (D3 receptor)


Amisulpride hydrochloride is an atypical dopamine D2/D3 receptor antagonist with Kis of 2.8 and 3.2 nM for human dopamine D2 and D3, respectively. Amisulpride hydrochloride (100 nM) inhibits quinpirole-elicited [3H]thymidine incorporation with an IC50 value of 22±3 nM (n=3). Amisulpride hydrochloride slightly but significantly increases [3H]dopamine release from slices of the rat striatum (S2/S1=0.88±0.04 under control conditions, n=6; 1.04±0.08 in the presence of 100 nM Amisulpride hydrochloride,n=4; P<0.05) and opposes the inhibitory effects of 7-OH-DPAT in both brain areas[1].


Only the highest dose of Amisulpride hydrochloride (100 mg/kg) significantly reduces dopamine levels in the striatum or limbic system. Amisulpride hydrochloride significantly increases the synthesis of dopamine in the rat striatum and limbic system at doses of 20 and 100 mg/kg. Amisulpride hydrochloride (0.5 to 75 mg/kg) fails to provoke an additional increase in dopa accumulation in the striatum but slightly accelerates, at 75 mg/kg, dopamine synthesis in the limbic system. In comparison with vehicle-treated controls, Amisulpride hydrochloride (10 mg/kg) increases extracellular dopamine levels. The administration of Amisulpride hydrochloride (0.5 to 15 mg/kg s.c.) provokes a time- and dose-dependent increase in the stimulation-evoked dopamine release. Amisulpride hydrochloride decreases striatal ACh levels significantly at 30 and 100 mg/kg (87.5% and 56.3% of control levels, respectively)[1]. In both acute study, Amisulpride hydrochloride (70 mg/kg, p.o.) significantly increases the duration of swimming behavior [F(3,28)=45.90, p<0.01][2].
