Mechanism and action
Lamictal: Lamotrigin blockiert selektiv spannungsabhängige Natriumkanäle, stabilisiert neuronale Membranen und reduziert die Freisetzung exzitatorischer Neurotransmitter, insbesondere Glutamat. Viagra Professional: Sildenafilcitrat hemmt die PDE5, sodass das während der sexuellen Erregung produzierte zyklische GMP im Penisgewebe akkumulieren kann, was die glatte Muskulatur der Penisarterien entspannt und den Bluteinstrom erhöht.
