What
is Viagra?
Viagra is the most well-known treatment for
adult men with erectile dysfunction, sometimes known as impotence. This is when
a man cannot get, or keep a hard, erect penis suitable for sexual activity.
Viagra is one of a class of drugs known as PDE-5 (Phosphodiesterase type 5)
inhibitors. Viagra and the other PDE-5 inhibitors can help men with erectile
dysfunction (male impotence) by enhancing the erectile response when a man is
sexually stimulated. You can also now purchase Viagra
online from any of the preferred online med stores.

How does Viagra work?
Viagra belongs to a class of medication known
as PDE5 inhibitors. In the presence of sexual stimulation, PDE5 inhibitors such
as Viagra relax smooth muscle and increase blood flow to the penis, helping to
restore impaired erectile function. Viagra mechanism of action. Let’s know a
little more-
Viagra has Sildenafil as the active ingredient
which is a PDE5 inhibitor. PDE5 is a chemical that slows down the blood flow in
our body. By preventing that chemical Sildenafil relaxes the blood vessels so
that blood can flow freely to the penis. Viagra also helps as a nitrate drug.
Nitrous oxide with the combination of sexual stimulation can create an
erection. As a nitrate drug, Viagra produces nitrous oxide and also prevent the
downfall of cGMP. Thus, Viagra helps a man with impotence in having the perfect
erection.
