Mechanism and action
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. Prometrium: Progesteron in Prometrium bindet an Progesteronrezeptoren und moduliert die Genexpression in reproduktiven und anderen Geweben.
