title: Inhibition of platelet serotonin uptake by cytochrome P450 inhibitors miconazole and econazole.
abstract: Serotonin uptake in human platelets was inhibited by cytochrome P450 inhibitors such as miconazole and econazole but not clotrimazole. There was a correlation between inhibition of serotonin uptake and inhibition of imipramine binding, suggesting that these P450 inhibitors may inhibit serotonin uptake via direct binding to the transporter. P450 inhibitor effects on serotonin uptake did not seem to be related to the effects of these compounds on intracellular calcium mobilization. Additionally, nitric oxide pathway stimulation does not appear to be involved.
