NCI Drug Dictionary

  

haloperidol 
A phenylbutylpiperadine derivative with antipsychotic, neuroleptic, and antiemetic activities. Haloperidol competitively blocks postsynaptic dopamine (D2) receptors in the mesolimbic system of the brain, thereby eliminating dopamine neurotransmission and leading to antidelusionary and antihallucinagenic effects. Antagonistic activity mediated through D2 dopamine receptors in the chemoreceptive trigger zone (CTZ) accounts for its antiemetic activity. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
