How does this work?
When a man gets sexually aroused, his brain directs blood flow the arteries in his penis. Pressurized blood is released and held in the penis for the duration required. This causes the same to harden during arousal and sex. After the same, the blood dissipates and the penis softens. However, with erectile dysfunction, the blood flow to the various arteries is blocked for various reasons making it difficult to achieve an erection. It contains a drug called phentolamine which relaxes the arterial walls and allows blood to flow and reach the desired level of pressure for an erection. This is usually done by a naturally occurring enzyme called cyclic guanosine monophosphate (cGMP) which is deactivated by another natural enzyme phosphodiesterase (PDE5) which only affects the penis. By eliminating the PED5, this drug allows the cGMP to build up in the penis which affects the arterial walls. Viagra stops or reduces the production of PED5 and this allows a person to achieve erection with no issues and eventually the effect wares off naturally.
