Ovestin: Estriol in Ovestin bindet an Östrogenrezeptoren mit kürzerer Rezeptorbindung als Estradiol und erzeugt dadurch einen schwachen östrogenen Effekt. Hydrochlorothiazide: Hydrochlorothiazid hemmt den Natrium-Chlorid-Symporter im distalen gewundenen Tubulus der Niere, reduziert die Natriumrückresorption und bewirkt eine moderate Diurese.
