Levitra), can stop the reaction in PDE6 resulting in side effects affecting vision.
According to the company, thirty percent of the 30,000,000 patients suffering from erectile dysfunction do not respond to drugs like Viagra, Cialis and
Levitra, in part due to an underlying degeneration of the biological machinery needed to achieve erections.
According to the National Institutes of Health, approximately 30m men in the US suffer from Erectile Dysfunction (ED), of which 9m do not respond to pharmacological treatments such as Viagra,
Levitra and Cialis.
They were randomly divided into three groups; 10 men were given sildenafil (Viagra) at 50 mg twice a week, 10 were given tadalafil (Cialis) at 20 mg twice a week, and 10 were given vardenafil (
Levitra) at 20 mg twice a week.
Earlier in his career, Derkacz has worked for more than 15 years at GlaxoSmithKline for major brands including
Levitra, Paxil, Coreg and its adult vaccine portfolio.
Drugs like Cialis,
Levitra and Viagra can help in some cases.
* "
Levitra Super Force" and "Viagra Super Force." Although
Levitra (vardenafil) and Viagra (sildenafil) are FDA-approved medicines used to treat erectile dysfunction,
Levitra Super Force and Viagra Super Force are not FDA-approved products and claim to contain dapoxetine.
A fake version of
Levitra, used to treat erectile dysfunction, is on the market while counterfeits of Yasmin, a contraceptive pill used to prevent pregnancy, can also be found.
This should drive down not only the price of Viagra but also of Eli Lilly's Cialis and Bayer's
Levitra.
