Cenforce 200 mg is a powerful medication used to treat erectile dysfunction (ED), primarily containing Sildenafil Citrate. Sildenafil works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which regulates blood flow in the penis. During sexual stimulation, nitric oxide is released in the penile tissue, stimulating the production of cyclic guanosine monophosphate (cGMP). cGMP relaxes smooth muscles and increases blood flow to the corpus cavernosum, leading to an erection.
