Mechanism and action
Prometrium: Progesteron in Prometrium bindet an Progesteronrezeptoren und moduliert die Genexpression in reproduktiven und anderen Geweben. Celexa: Citalopram hemmt selektiv den Serotonin-Reuptake-Transporter und erhöht damit die synaptische Serotoninverfügbarkeit, mit nur begrenzter Affinität zu Noradrenalin-Transportern oder anderen Rezeptoren.
When Prometrium is preferred
Prometrium ist zum Endometriumschutz bei postmenopausalen Frauen unter Östrogentherapie, bei sekundärer Amenorrhoe und ausgewählten ART-Indikationen zugelassen.
When Celexa is preferred
