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. Pepcid: Famotidin blockiert reversibel und kompetitiv die Histamin-H2-Rezeptoren an den Belegzellen des Magens und vermindert sowohl die basale als auch die stimulierte Magensäuresekretion.
