Sodium-dependent interaction of benzamides with dopamine receptors
Brain Research
|September 29, 1980
Abstract:
Sulpiride and other benzamide (BM)-displacing activity on [3H]-spiroperidol ([3H]SPIR) binding by rat striatal dopaminergic receptors was found to be uniquely sodium-dependent, while classical neuroleptic (NL) activity was not influenced by NaCl. These results suggest the existence of at least two populations of striatal dopaminergic receptors, sodium-dependent and sodium-independent, through which BM and NL respectively interact.
