Business Description

Sildenafil citrate works by inhibiting the action of the enzyme phosphodiesterase type 5 (PDE5), which is responsible for breaking down cyclic guanosine monophosphate (cGMP) in the corpus cavernosum of the *****. Increased levels of cGMP lead to relaxation of smooth muscles in the blood vessels of the *****, allowing for increased blood flow and thus an erection.
