Exactly 15 years back, Michael Allen received a call from a doctor residing in a small Welsh town, which was actually the first indication of an innovation's emergence. The doctor had been working on a small clinical trial involving the examination of a new drug for the treatment of angina. The future of the new drug called UK-92480 seemed bleak then as other trials had revealed that it did not engender much impact on the disease and was less efficient than existing treatments.
When the doctor presented his progress report to Allen, a clinical project manager at pharmaceutical giant Pfizer, he also cited some side effects that occurred in the healthy volunteers during the trial in Merthyr Tydfil. They were indigestion, back pain and erections.
Erectile dysfunction is often a sign of a more severe vascular problem that involves abnormalities in the lining of the blood vessels. And often, endothelial dysfunction is an underlying problem for erectile dysfunction - it can be one of the first signs of atherosclerosis.
After five years of detailed research, Pfizer applied to get marketing approval for the same drug, but not to treat angina, in fact for male impotence. Since then Viagra has been utilized by over 30 million men across the globe for erectile dysfunction or impotence.
Researchers believe that the wonder blue pill may also come handy for a host of other uses. They say it might be a versatile potion as Aspirin.
The health conditions that Viagra has been assessed to treat include jet lag, premature ejaculation, heart failure, diabetes symptoms, pain, multiple sclerosis, premature birth, memory loss, chronic pelvic pain, reynaud's phenomenon, and strokes.
While Egyptians used Viagra to save unconsummated marriages, it has been examined as a new therapy to cure jet lag in Argentina. Not only this, in Israel researchers have also noticed that it can help slashed flowers to survive long.
