Mechanism and action
Synthroid: La lévothyroxine remplace la thyroxine endogène déficitaire, convertie dans les tissus en hormone active, la triiodothyronine (T3), par les enzymes désiodases. 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 Synthroid is preferred
