Serotonin Syndrome Induced by Venlafaxine and Fluoxetine: A Case Study in Polypharmacy and Potential Pharmacodynamic and Pharmacokinetic Mechanisms

Abstract: As more serotonergic drugs are developed and used for psychiatric disorders, frequently in combination or close temporal proximity, clinicians must be aware of and consider the factors that may increase the risk of patients experiencing serotonin syndrome.

“…Auch die Einnahme von Venlafaxin zusätzlich oder kurz nach dem Absetzen eines anderen Serotoninwiederaufnahmehemmers wie z. B. Fluoxetine kann ein Serotonin-Syndrom induzieren [9]. Eine Rhabdomyolyse wurde bisher nur in einem Fall bei der kombinierten Einnahme von Venlafaxin und Lamotrigen beschrieben [10].…”

“…Furthermore, venlafaxine is dependent on CYP2D6 and CYP3A3/4 for its phase I biotransformation, while fluoxetine can inhibit many isozymes including CYP2D6 and CYP3A3/4. The serum level of venlafaxine might increase rapidly with coadministered fluoxetine 1 . The combination use of venlafaxine, fluoxetine, trazodone and buspirone has the potential for pharmacodynamic and pharmacokinetic drug interactions, which result in increasing CNS serotonin transmission and inducing serotonin syndrome.…”

“…Venlafaxine, a serotonin-norepinephrine reuptake inhibitor, has been reported to be associated with serotonin syndrome, especially in patients who receive two or more drugs that enhance CNS serotonin activity. [1][2][3][4][5][6][7] Venlafaxine has been considered a safe choice in treating major depressive episode for patients with bipolar II disorder. 8 However, sporadic cases have been reported to have venlafaxine-induced 'manic and hypomanic switches'.…”
