What is Levitra?
Levitra is the brand-name for vardenafil, a new tablet-based
oral treatment for erectile dysfunction (ED), which is
licensed for prescription in the UK and other countries,
enabling you to buy it online. Levitra has proved highly
successful in clinical trials and is generating major
interest as a real alternative to Viagra, Uprima and
Cialis.
Levitra is a new oral PDE-5 inhibitor for the treatment
of male erectile dysfunction (ED). Phosphodiesterase
type 5 (PDE-%) is the predominate enzyme found in human
penile erectile tissue and is associated with erections.
PDE-5 inhibitors such as Levitra typically work by blocking
this enzyme to enhance or prolong the erectile process.
Levitra is marketed by the leading pharmaceutical companies
Bayer and GlaxoSmithKline, through a worldwide co-promotion
and co-development agreement.
Where can I get Levitra?
It is possible to buy genuine Levitra and buy it online.

How effective is Levitra for Impotence?
In Clinical Studies, Levitra Improved Quality of Erections
and Demonstrated Rapid and Reliable Response
Bayer and GSK evaluated Levitra in an extensive clinical
trial program that included more than 50 trials involving
more than 5,700 men. Results from phase III clinical
studies showed that Levitra:
-- Helped men get and keep an erection sufficient for
satisfactory sexual performance
-- Provided first-time success and reliable improvement
of erection quality for many men(2,3)
-- Worked in men of various ages and race and in those
with co-existing medical conditions, such as diabetes,
and in men who have had their prostate removed
-- Demonstrated a rapid response, allowing a man to
initiate or respond to sexual stimulation when the time
is right(4)
-- Can be taken without regard to meals making it convenient
for use
Levitra has sparked major interest worldwide following
the results of an in-depth clinical study. The study
of over 800 men with ED showed:
The vast majority treated with Levitra experienced a
reliable improvement in their erectile function from
the first time they took the drug, and each time they
took it afterward.
74% of men taking a 20 mg dose of Levitra and 77% taking a 10 mg dose
were able to have intercourse on their first attempt, compared with
45% taking a placebo.
Those men receiving treatment who were successful the first time continued
to achieve successful penetration in 91% of their subsequent attempts.
These results - recently presented at the 10th World Congress of the
International Society for Sexual and Impotence Research in Montreal
- have been welcomed by clinicians. This initial research has shown
that Levitra gives more consistent results than other treatments on
repeated use.
Levitra and ED-related depression
A second study has shown how effective Levitra was
in treating the depressive symptoms experienced by men
with ED. This study showed men taking Levitra reported
improved erections and fewer depressive symptoms than
those men taking a placebo.
Levitra and ED after prostate surgery
Levitra is extremely effective in treating ED following
prostate cancer surgery. Another trial involving 440
men aged 44 - 77 years with ED
Following a prostate surgery found:
71% of patients who had undergone prostate removal reported
significant improvements in erections with Levrita (20mg)
versus 12 per cent in men taking placebo.
The study concluded that this was an important finding for Levitra,
as ED following prostatectomy is usually severe.
Is Levitra more effective than Viagra?
There is currently no direct evidence to compare the
effectiveness of treatments such as Levitra, against
others such as Viagra and Uprima. However, findings do
indicate that Levitra may be especially effective in
treating specific types of ED, such as ED resulting from
prostate surgery. . In clinical trials, Levitra was shown
to work quickly as early as 16 minutes. More importantly,
Levitra was shown to improve the sexual response for
the majority of men the first time they took it, and
it worked consistently over time.
Does Levitra have side-effects?
Those involved in the clinical trials reported mild
/ moderate side effects with the treatment, these mostly
included headaches, flushing and rhinitis (nasal congestion).
For otherwise healthy men, Levitra's main side effects
were headache, flushing and a stuffy nose. About 2 percent
became dizzy.
Who should avoid taking Levitra?
All patients should get a yearly physical checkup.
If you feel or know you have a heart problem or taking
medication for your heart, you should definitley check
with your local doctor to see if Viagra or Levitra is
right for you.
Levitra should not be taken if you are taking nitrates
or nitric oxide donors (these medications are used to treat
angina or chest pain). It is also contraindicated in men
whom sex is inadvisable and men older than 75 years old
who concomitantly use potent CYP 3A4 inhibitors (such as
ritonavir, indinavir, ketoconazole and itraconazole). The
safety of Levitra has not been studied in these subgroups
and should not take Levitra until further studies are available:
severe hepatic (liver system) impairment , endstage renal
disease requiring dialysis, hypotension, recent history
of stroke or heart attack, unstable angina, and known hereditary
retinal degenerative disorders.
The FDA said Levitra should never be used by men who:
* Take nitrate-containing drugs for heart conditions.
* Take medicines called alpha blockers, such as Cardura,
for high blood pressure or enlarged prostate. The combination
could cause plummeting blood pressure and fainting.
FDA also said Levitra is not for patients with a rare
heart condition known as QT prolongation because the
drug could cause an abnormal heart beat. QT prolongation,
which is increased time between heart waves, this condition
could result in rare cases of abnormal heart rhythms.
The FDA said patients taking Levitra should see a doctor
immediately if they faint, which could be a symptom of
this condition.
Nor is it for men who suffered a recent heart attack
or stroke who have very low blood pressure or uncontrolled
high blood pressure.
For otherwise healthy men, Levitra's main side effects
were headache, flushing and a stuffy nose. About 2 percent
became dizzy.
Men are advised to get a thorough physical exam before
using Levitra for the first time, the FDA said.
