Fluphenazine hydrochloride

Fluphenazine hydrochloride is an effective, orally active phenothiazine class dopamine receptor (dopamine receptor) antagonist. It blocks voltage-gated sodium ion channels (sodium channels) in neurons. The compound primarily exerts its effects by antagonizing postsynaptic dopamine-2 receptors in mesolimbic, nigrostriatal, and tuberoinfundibular pathways. It counteracts stereotypy induced by methylphenidate in mice and suppresses climbing behavior. Fluphenazine hydrochloride is used in studying psychoses and diabetic-related painful peripheral neuropathy, with potential to inhibit SARS-CoV-2.
