title: Diazepam potentiation of purinergic depression of central neurons.
abstract: Intravenously or iontophoretically applied diazepam potentiated the depressant action of iontophoretically applied 5'-AMP on the spontaneous firing of rat cerebral cortical neurons. This potentiation of purinergic depression may be a result of the previously reported inhibition by diazepam of uptake of adenosine into brain tissues.
