How does Tadalafil work?
Penile erection during a sexual stimulation is caused by increased blood flow into the penile arteries. To ensure increased blood flow the muscles should be relaxed. A compound called as cGMP enables this relaxation. An enzyme called phosphodiesterase type 5 (PDE5) prevents the synthesis of cGMP, thereby not allowing the muscles to smoothen and relax, which results in erectile dysfunction. Tadalafil acts on this enzyme and inhibits its action; thereby enabling the synthesis of cGMP and allowing increased blood supply to penile arteries. Cialis is approved by FDA. Due to the longer duration of action, which is up to about 36 hours, Tadalafil has earned the name as a “weekend pill”. You can order Tadalafil online through this website.
