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. Stendra: Avanafil hemmt selektiv die Phosphodiesterase Typ 5 (PDE5) im Schwellkörper, erhöht die cGMP-Konzentration und verstärkt die durch Stickstoffmonoxid vermittelte Vasodilatation als Reaktion auf sexuelle Stimulation.
