Sildenafil Citrate is the main active ingredient of Cenforce, a well-known and successful treatment for erectile dysfunction (ED). The way sildenafil works is by inhibiting phosphodiesterase type 5 (PDE5), an enzyme that is essential for controlling blood flow in the body. Nitric oxide is produced in the penile tissue during sexual excitement, which causes an increase in the synthesis of cyclic guanosine monophosphate (cGMP). Increased levels of cGMP facilitate the relaxation of smooth muscle and augment blood circulation to the corpus cavernosum, ultimately contributing to the attainment of an erection. Cenforce 100 review may be purchased for a reasonable cost.
