MONOAMINE-OXIDASE INHIBITORS POTENTIATE PHENYLETHYLAMINE EFFECTS IN RHESUS-MONKEYS

Acute pretreatment with either a Type A monoamine oxidase inhibitor (MAOI), clorgyline, or a Type B MAOI, pargyline, markedly reduced the dose of phenylethylamine (PEA) required to produce checking and a variety of other behavioral changes in rhesus monkeys. Doses of PEA (5 or 10 mg/kg) which previously were without effect, now produced significant behavioral changes in pretreatment animals.
