Cenforce 130 mg is a prescription medication containing sildenafil citrate, used primarily to treat erectile dysfunction (ED) in men. Sildenafil is part of the phosphodiesterase type 5 (PDE5) inhibitor class of drugs, which work by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain a firm erection. During sexual arousal, nitric oxide is released in the penile tissue, which increases cyclic GMP (cGMP) levels. cGMP relaxes the smooth muscles of blood vessels in the penis, allowing increased blood flow. https://www.genericday.com/cenforce-130-mg.html
