Viagra and its History
More than 20 million men suffer from erectile dysfunction and probably as much in Europe. And to many, Viagra has been an answer for this.
The history of Viagra dates back to 1992 when Viagra was accidentally discovered in Pfizer’s Sandwich while making a clinical study on Sildenafil citrate. Supposedly it has been made for cardiovascular diseases, but it led to another therapeutic effect. Patients who actually were participants to the trail didn’t wish to give back the tablets. Later the found out that most men included during the trial have experienced improvement on erectile function. The word ‘Viagra’ is derived from ‘vigor’ meaning power and ‘Niagara’ which is the Niagara Falls.
Introduced in March 1998, doctors wrote over a hundred thousand prescriptions of Viagra each week in the United States. That time, per pill costs $10. After three months, about 2million prescriptions were issued. It then became popular calling it Herbal Viagra, Vitamin V or Magic blue pill. In 2000 with the existence of online pharmacy, its sales even reach $1 billion. Together with these comes the spread of cheaper Viagra, whether online or over the counter.
Well much like Viagra, Tadalafil started out in 1993 and conducted tests for heart disorders. Almost similarly after Viagra came out, Icos and Eli Lilly and Co. has commercialized Tadalafil for sexual dysfunction treatment. In 2000 the company has changed the drug name to Cialis and has filed new drug application at the US Food and Drug Administration. After three years, FDA approved it. Although in Europe it has been approved a year earlier. Cialis boasts its ability to sustain its effect for 36 hours.
Most community pharmacies sells these medications however you can also buy Cialis online and make sure you’ll get only the original and high-quality pills.
While Cialis brags its longer effectivity, Levitra however advertises to see the satisfying effects in just 16 minutes and may actually last longer than Viagra which could take up to 5 hours.
Levitra or vardenafil was launched in March, 2003 in the United Kingdom. Shortly after this, in August of the same year, Bayer AG and GlaxoSmithKline Plc gained approval in the United States. The name was actually derived from the French word ‘le’ meaning masculine and the Latin word for life, ‘vita’.
To find for some relatively cheaper ones, order levitra online and save more when you order in bulk.
