When Ovestin is used
Ovestin-Vaginalpräparate sind zur Behandlung und Prävention der urogenitalen Atrophie und rezidivierender Harnwegsinfekte bei postmenopausalen Frauen sowie in einigen Märkten zur Vorbereitung vor gynäkologischen Eingriffen zugelassen.
When Clavulanate is used
Clavulansäure ist nur als Bestandteil von Festdosis-Kombinationen mit einem anderen Beta-Lactam-Antibiotikum zugelassen.
Mechanisms compared
Ovestin: Estriol in Ovestin bindet an Östrogenrezeptoren mit kürzerer Rezeptorbindung als Estradiol und erzeugt dadurch einen schwachen östrogenen Effekt. Clavulanate: Clavulansäure bindet irreversibel an das aktive Zentrum vieler von Bakterien produzierter Beta-Lactamasen der Klasse A und wirkt als 'Suizid-Inhibitor'.
