New Erectile Dysfunction ED Drugs
and How They Measure Up Versus Viagra

Since the first ED Erectile Dysfunction Drug Viagra was
approved by the FDA in 1998, the number of men diagnosed
with Erectile Dysfunction in the US has increased by over 250
percent. So there is no wonder why two new ED Erectile
Dysfunction Drugs have recently hit the market. Levitra offers a
much smaller dose, 10 milligrams compared with the 100 mg for
Viagra. The Erectile Dysfunction Drug Cialis, on the other hand,
stays active in the body much longer than the other two drugs.
24-36 hours compared to 4-5 hours for Viagra and Levitra.
Cialis also works faster, 15-30 minutes compared with an hour
for Viagra. The three Erectile Dysfunction Drugs also have many
similarities: The three ED Drugs all work by relaxing smooth
muscle cells, thereby widening blood vessels. None of the
Erectile Dysfunction Drugs produce an erection. Rather, they
make an erection possible with sexual arousal. Resulting side
effects are comparable and may include headaches, heartburn,
and flushing. The FDA advises against mixing these Erectile
Dysfunction Drugs with alpha blockers and nitrate medications.
Even with the introduction of these two new ED Drugs, the
decision to medicate Erectile Dysfunction should be carefully
considered with a physician and will vary among male patients.

Erectile Dysfunction Drug Studies To Date Say ED Drugs
Affect Other Systems, Mostly For The Better

Studies so far suggest the Erectile Dysfunction ED Drugs,
called phosphodiesterase-5 inhibitors produce mostly beneficial
results, and not just for Erectile Dysfunction. The FDA recently
approved a reformulation of sildenafil for the treatment of
primary pulmonary hypertension, While there are some
differences among the three ED Drugs, they have many
properties in common and work by limiting the activity of the
enzyme phosphodiesterase-5, which is found in tissues and
vessels of the penis, blood platelets, and smooth muscle of
blood vessels. For the treatment of Erectile Dysfunction, the
drug constraint of the enzyme's action results in increased levels
of cyclic guanosine monophosphate and nitric oxide which are
biochemicals that promote smooth muscle relaxation and
increased blood flow in erectile tissue. PDE-5 inhibitors actually
improve blood flow even in areas where there is a blockage of
an artery, thereby having a protective effect on the heart muscle.
