Mechanism and action
Allegra: La fexofénadine bloque sélectivement les récepteurs H1 périphériques de l'histamine, antagonisant ses effets sur la vasodilatation, la perméabilité capillaire, les terminaisons nerveuses sensitives et le muscle lisse. Cialis Super Active: Le tadalafil inhibe la PDE5 dans le tissu pénien lors de l'excitation sexuelle, ce qui permet au GMP cyclique de s'accumuler, au muscle lisse de se relâcher et à l'afflux sanguin d'augmenter.
When Allegra is preferred
