Lunesta: Eszopiclon ist ein positiver allosterischer Modulator des GABA-A-Rezeptors an einer Bindungsstelle nahe der Benzodiazepin-Bindungsstelle. Spironolactone: Spironolacton blockiert den Aldosteron-(Mineralokortikoid-)Rezeptor im distalen Tubulus kompetitiv und reduziert dadurch die Natriumrückresorption und die Kaliumausscheidung.
