    Abstract

    Phencyclidine inhibited uptake in vitro of [3H]norepinephrine (ic50 0.52 μM), [3H]dopamine (ic50 0.73 μM) and [3H]serotonin (ic50 0.80 μM) in crude synaptosomal preparations from rat brain through a competitive mechanism. Phencyclidine was fairly similar in potency to d-amphetamine and methylphenidate in inhibiting catecholamine uptake but was 8 times more potent than d-amphetamine and 34 times more potent than methylphenidate in inhibiting [3H]serotonin uptake.
