The time-course of effects of a single dose of p-chlorophenylanine on rat brain amines shows a significant lowering of serotonin (5HT) and 5-hydroxyindole-3-acetic acid (5HIAA) beginning on day 1 and lasting for about 8 days. In most brain areas, levels of norepinephrine (NE) are also lowered significantly on days 1 through 5. In contrast, both p-chloroamphetamine and p-chloro-N-methylamphetamine decrease brain 5HT and 5HIAA, beginning at 2-4 hr after dosage and continuing for > 4 days, with no depleting effect on brain NE.
