چکیده

BACKGROUND Although several studies show that there is an increased risk of bleeding events during antidepressant treatment with selective serotonin reuptake inhibitors (SSRIs), few studies show direct effects in vitro of SSRIs on hemostasis. METHODS This study was undertaken to investigate the effects on platelet adhesion and plasma coagulation (APTT and PT) of two common SSRIs, citalopram and sertraline, the selective noradrenaline reuptake inhibitor reboxetine, and the serotonin and noradrenaline reuptake inhibitor venlafaxine. RESULTS None of the compounds affected plasma coagulation significantly but all compounds except for venlafaxine inhibited platelet adhesion by approximately 50% or more at the highest concentration (100 μg/l, p < 0.01). The potency of respective compound to inhibit platelet adhesion to both collagen and fibrinogen surfaces was in the following order; citalopram > sertraline > reboxetine. In contrast, venlafaxine caused a weak but statistically significant increased platelet adhesion to fibrinogen. CONCLUSION This study showed that sertraline, citalopram and reboxetine direct and acutely decrease platelet adhesion to both collagen and fibrinogen in vitro. These results also indicate that increased risk for bleeding complications in antidepressant users may not only be explained by depletion of serotonin in platelets.

EFFECTS OF CATECHOLAMINES ON DOPAMINE AND SEROTONIN SYNTHESIS IN RAT BRAIN STRIATAL SYNAPTOSOMES: THE ROLE OF PRESYNAPTIC RECEPTORS AND THE SYNAPTOSOMAL REUPTAKE MECHANISM.

The regulation of dopamine and serotonin synthesis in rat brain striatal synaptosomes has been studied using HPLC methods. Noradrenaline was shown to markedly inhibit both the synthesis of dopamine and serotonin. The response of the synaptosomes to the concentrations of noradrenaline appeared to be biphasic, a very effective inhibition occurring at low concentrations (1-5 µm) and a relativ...
