David
and Michael are the best of friends. Thy live next door.
They have been friends from childhood. In fact, they went
to the same school, were in the same football team. Each
has two children .Their wives are also each other's best
friends. They even had health problems at the same time.
Similiarly, they had the same terrible impotence problem
at the same time, when they turned 45. That's where
the similarities end… While David prefers the
new blockbuster drug Levitra , Micheal on the other
hand swears that old is gold and uses Viagra.
Impotence or Erectile Dysfunction , since time memorial,
has been a problem for men as they age. Erectile Dysfunction
is defined as the inability to ensure or sustain an
erection for satisfactory sexual intercourse. This definition
covers all aspects of sexual dysfunction, including
that of men who have an erection, but are unable to
hold it for more than a minute or men who have a soft
erection. It affects more than 150 million all over
the world. The shocking fact is that, only 5% of these
men actually get themselves treated or for that matter
see a doctor for it. It probably has to do with the
past.
Most of the men who saw a doctor before 1998 had to
do with painful and rather crude therapies. These included
painful intracavernosal injections ( in the corpus cavernosa,
a muscular fibrous tissue which expand when an erection
happens) or intraurethral injections(in the urethra,
through which we urinate) which were used as vasodilators
to dilate the blood vessels and get an erection.These
therapies were so cumbersome, painful and inconvenient,
that most men were reluctant to try them. Then Viagra
happened, and changed everything.
In 1998, When Pfizer launched Viagra, it actually rewrote
a new chapter in the history of sex and male sexuality.
It started a new sex revolution in men, who thought,
that as far as they were concerned sex was history.
Viagra contained a revolutionary new drug called Sildenafil
Citrate. It was Viagra which solved a problem, which
researchers had faced for many years - an effctive drug
to deal with erectile dysfunction. Since erectile dysfunction
is caused mostly by the inability of blood vessels to
dilate or remain dilated over the period of time required
for satisfactory sexual intercourse. It was difficult
to get a specific drug to act only on the blood vessels
of the penis and not other parts of the body.
Viagra increased the levels of a very important vasodilator
called nitric oxide which dilated the blood vessels
and increased blood flow in to the penis and bingo…we
had an erection. Now this is the easier way of explaining
how Viagra worked. Viagra actually blocks Phosphodiasterase-5(PDE-5)
, an important enzyme which degrades another enzyme
called cyclic guanosine monophosphate(cGMP) which is
responsible for ensuring high levels of nitric oxide
and therefore vasodilation and so a strong erection.
Viagra, because it has been in the market for so long,
has been able to prove it's efficacy and potency over
a period of time. It acts as early as 15 minutes. But
if a person has a hearty fat filled meal and then wants
to have sex with Viagra, then he has to wait longer,
for it to act.. Viagra works very well for the full
4 hours. Men who swear by Viagra, believe this is adequate
time to enjoy a satisfactory sexual intercourse. Be
it men with prostate problems or surgery or any other
condition, Viagra has worked like magic. If experience
really makes a difference, then 7 years of safe clinical
experience and 20 million men who have tried it, would
safely vouch for Viagra. However Viagra is not without
it's detractors. And they are men who have had problems,
after taking Viagra .
Men taking Viagra have constantly suffered Vision problems
starting from bluish discolouration of the eye to blurred
vision. Other vision problems include an increased sensitivity
to light and the inability to distinguish between blue
and green. This is because Viagra also acts on the enzyme
PDE-6 present in the eye. Viagra can also adversely
affect the heart in people with pre-existing heart disease.But,
what really puts off most men is the fact that Viagra
does not always work the first time, they take it. They
have to keep on trying and then it may work or maybe
not. It works on less than half the diabetic patients,
who take it. Many men tried Viagra initially and were
so disappointed that they just stopped using it altogether.
These men waited desperately for an altenative and it
came with - Levitra
When Glaxo Smithkline Beecham along with Schering Plough
and Bayer AG, some of the most established pharmaceutical
companies in the world, decided to jointly put all their
energy into a completely new molecule, they never could
have imagined the kind of gift they were giving millions
of long suffering men with Levitra. A drug like no other
which contains Vardenafil, from the same class of drugs
as sildenafil, which is a blocker of the enzyme PDE-5.
But there is a difference here. Levitra has a much stronger
action than Viagra, and is much more potent. Therefore
it ensures stronger and more longer erections for men,
who take it. This enhances the quality of sexual intercourse.
Another beneficial factor is the quick onset of action
- barely 16 minutes, which is not affected by the food
eaten. So, men can go ahead have that fat filled hearty
meal and have quality sex after that.
But what makes Levitra really stand out is solid scientific
data in the form of the PROVEN Study. A trial which
proved that Levitra could work in men who had tried
Viagra or other treatments and had been disappointed.
463 men took part in this study. All these men had tried
Viagra atleast 6 times and failed atleast 4 times. The
study showed that the success with Levitra was three
times greater and especially so in a very important
patient group - Diabetic men. At, last here was a drug
that worked in diabetic men and worked really well.
No wonder Levitra was able to grab 50% share of new
prescriptions for erectile dysfunction in the very first
month of it's launch. Not only that, Levitra also offers
the same benefits in certain subgroups of patients like
men with Coronary artery disease who could not use other
drugs for erectile dysfunction. In, fact Levitra protects
the heart from tissue damage after a severe heart attack.
Levitra also improved depressive symptoms in men with
erectile dysfunction and depression.
With so many benefits Levitra has truly emerged as
the heir apparent to succeed a fast fading Viagra,.While
Viagra is a blue coloured diamond shaped scored tablet.
Levitra is a bright orange coloured tablet with the
flame logo on it. Viagra is available in three strengths
, 25mg 50mg and 100mg, while. Levitra is available in
more convenient four strengths, 2.5mg, 5mg, 10mg and
20mg. All these strengths clearly show the potency of
Levitra and at the same cost as Viagra.
If one buys Levitra online it is even cheaper
More Viagra information is available on Pfizer's official
website, Viagra.com
More Levitra information is available at Levitra.com,
the official website of Bayer, Glaxosmithline Beecham
and Schering Plough. What really turns the odds in fvour
of Levitra, is the important fact that the best armed
force in the world, the US military has allowed only
Levitra to be given to its men for erectile dysfunction.
Now is that's a strong signal as to which is the best
drug to go for or does Micheal still disagree?.
