Tadalafil Tablets (generic Cialis)

1. What is Tadalafil?

Brand name: Cialis

Mechanism of action: Tadalafil is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). The physiologic mechanism of erection of the penis involves release of nitric oxide (NO) in the corpus cavernosum during sexual stimulation. Nitric oxide then activates the enzyme guanylate cyclase, which results in increased concentrations of cGMP. Cyclic guanosine monophosphate causes smooth muscle relaxation in the corpus cavernosum thereby allowing inflow of blood.

2. What does Tadalafil do for erectile dysfunction? 

Tadalafil is rapidly absorbed after oral administration. It helps increase erection duration during intercourse. The usual duration can last up to 36 hours.
