Perphenazine-d₄is intended for use as an internal standard for the quantification of perphenazine by GC- or LC-MS. Perphenazine is a typical antipsychotic.¹It binds to dopamine D₂, α_1A-, α_2A-, α_2B-, and α_2C-adrenergic, M₃muscarinic, and histamine H₁receptors (K_is = 1.4, 10, 1,848, 104.9, 85.2, 810.5 and 8 nM, respectively), as well as the serotonin (5-HT) receptor subtypes 5-HT_1A, 5-HT_2A, 5-HT_2C, 5-HT₆, and 5-HT₇(K_is = 421, 5.6, 132, 17, and 23 nM, respectively). Perphenazine (1, 5, and 10 mg/kg) enhances morphine-induced analgesia in the tail-flick and hot plate tests in rats.²It reduces cannibalism in female mice when administered at doses of 2 and 4 mg/kg.³Formulations containing perphenazine have been used in the treatment of schizophrenia and psychosis.
