Platelet Function in Patients Treated With SSRI and Non-SSRI Antidepressants
This study will examine the effect of a class of antidepressant medications called selective serotonin reuptake inhibitors (SSRIs) on platelet function. Platelets are small blood cells that help stop bleeding after injury to a blood vessel by forming a clot, or plug, in the vessel. Some medications impair platelet function, leading to increased bruising and bleeding. SSRIs decrease an important platelet component called serotonin, which may cause bleeding in some patients. SSRIs include fluoxetine (Prozac), sertraline (Zoloft), paroxetine (Paxil), fluvoxamine (Luvox) and citalopram (Celexa).
Patients 18 years of age and older being treated for depression with a SSRI or the non-SSRI bupropion (Wellbutrin) may be eligible for this study. Subjects will be recruited from a private clinic in Washington, D.C.
Participants will provide a history of their current medications and past history of bleeding. They will have about 4 tablespoons of blood drawn for tests to measure blood cell counts and platelet function. The study takes about 1 hour. The results of the SSRI-treated group and the bupropion-treated group will be analyzed and compared.
This study may provide information that will help health care providers make treatment decisions to minimize possible adverse effects of medications in patients with depression.
