Mechanisms compared
Acyclovir: Aciclovir ist ein Guanosin-Analogon, das durch die virale Thymidinkinase selektiv zur Monophosphat-Form und anschließend durch zelluläre Kinasen zu Aciclovir-Triphosphat phosphoryliert wird. Spironolactone: Spironolacton blockiert kompetitiv den Mineralokortikoid-Rezeptor (Aldosteronrezeptor) im distalen Tubulus der Niere, vermindert die Natriumrückresorption und die Kaliumausscheidung.
