Mechanisms compared
Estrace: Estradiol bindet an Östrogenrezeptoren (ERα und ERβ) in Zielgeweben und moduliert die Genexpression für vaskuläre, ossäre, reproduktive, zentralnervöse und metabolische Funktionen. Fluoxetine: Fluoxetin hemmt selektiv den Serotonin-Wiederaufnahmetransporter und erhöht so die synaptische Verfügbarkeit von Serotonin.
