title: Antidepressant drugs potentiate suppression by adenosine of neuronal firing in rat cerebral cortex.
abstract: Adenosine and AMP (5'-adenosine monophosphate) applied by microiontophoresis produced depression of neuronal firing rates in cerebral cortex. A number of antidepressant drugs including examples which are known not to affect noradrenaline uptake systems, potentiated the depressant purine effects. Noradrenaline responses were unaffected or reduced. Purines may therefore be important in the mechanism of action of antidepressant drugs.
