The active ingredient in Cenforce 150 mg blue pills is called sildenafil citrate. By blocking the action of phosphodiesterase type-5, a chemical that is naturally found in the penis, sildenafil treats erectile dysfunction.
Sildenafil Citrate helps to dilate (relax) the blood vessels during sexual activity. As a result, the amount of blood that flows through the body's penile region increases. This system helps men achieve and sustain a strong erection.
