How Viagra Works

Viagra contains sildenafil citrate, a PDE-5 inhibitor that works by:

• Blocking the enzyme phosphodiesterase type 5
• Allowing cyclic GMP (cGMP) to accumulate in the penis
• Relaxing smooth muscles and dilating blood vessels
• Increasing blood flow to facilitate an erection when combined with sexual stimulation

Without sexual stimulation, Viagra does not produce an erection.
