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. Toprol XL: Metoprolol blockiert selektiv Beta-1-Adrenozeptoren am Herzen, reduziert die Herzfrequenz, die Kontraktilität und die AV-Überleitungsgeschwindigkeit und senkt den myokardialen Sauerstoffbedarf.
