Answer 1

ED (erectile dysfunction) pills usually have the effect of causing vasodilation or widening of blood vessels. The pills target biochemical pathways to inhibit enzymes for example in viagra (inhibits phosphodiesterase 5 - PDE5) and this in turn leads to the abundance of the substance nitric oxide which is an endogenous vasodilator.

So basically vasodilation = more blood flow to the site and no more erectile dysfunction.

The pills are a short term fix as they block the pathways as they are taken and therefore once you stop taking them then the effect is gone.

Of course there are side effects too because such pills are targetting enzymes in a not 100% specific way and research has shown that in some people other nonspecific effects may occur, hence it isnt suitable for all.

Viagra is a prescription drug so you must go see a doctor and he will prescribe it to you if it will be necessary.
This med can also have side effects, so a visit to the doctor's office is highly recommended, especially for the 1st time users. Erectile dysfunction. The mushrooming of erectile dysfunction across the world has increased rapidly and consequently in spite
of sexual arousal, people are unable to achieve erections necessary for a rewarding sexual union.
Regardless of your feelings for your partner or the extent of your sexual stimulation, if ever you fall in the grip of impotency; all your attempts for a conjugal union with your wife would be of no avail. From this critical condition only Viagra can save you as Viagra power would make you sufficiently capable of combating the erectile dysfunction threat and paving your way for a satisfactory conjugal union.

As soon as the little blue pill Viagra is mixed with your blood, Viagra action against impotency triggers off. Viagra inhibits the phosphodiesterase type 5 enzymes (PDE5) and accelerates the functioning process of nitric oxide which is responsible for the proper flow of blood to the penis. As blood in abundance reaches the penis, rock hard solid erections are triggered off which eventually lead to satisfactory sexual union between partners. Any other anti-impotency drug would not provide you the multibenefits that can be easily gained through Viagra. The treatment of male impotency through drugs puts the patient at the risk of succumbing to prolonged painful erections medically known as priapism and as Viagra has been clinically proved as an effective treatment of this disorder, so Viagra care remains far more advantageous in comparison to any medicine invented so far for the treatment of erectile dysfunction.

Hi
from wiki:
Sildenafil citrate, sold as Viagra, Revatio and under various other trade names, is a drug used to treat erectile dysfunction and pulmonary arterial hypertension (PAH). It was originally developed by British scientists and then brought to market by the US-based pharmaceutical company Pfizer.[1] It acts by inhibiting cGMP-specific phosphodiesterase type 5 (PDE5), an enzyme that promotes degradation of cGMP, which regulates blood flow in the penis. Since becoming available in 1998, sildenafil has been the prime treatment for erectile dysfunction; its primary competitors on the market are tadalafil (Cialis) and vardenafil (Levitra)...
