Viagra Usage

Viagra is a prescription drug that works by increasing blood flow to the penis. Viagra is not a hormone or an aphrodisiac. Once you take viagra it can work as quickly as 30 minutes. In most cases, patients can take viagra as often as once a day.

The following is the statistical data on Viagra usage according to the year 2000 :

• Viagra (sildenafil) was approved by the FDA
  on March 27, 1998 .
• 280,000 U.S. physicians have since prescribed it
  for more than 6.1 million men.
• 18 million prescriptions have been written.
• 140 million tablets have been dispensed.
• 70% of all prescriptions are now for refills.
• 93% of the population recognizes the name
  (compared to 96% brand recognition for 'Coke.')
• The overall clinical trials experience to date totals
  more than 11,000 patient years of exposure.
• The concomitant use of organic nitrates remains the major contra-indication

With the passage of nearly 5 years the number of men taking Viagra have multiplied manifold, and this itself is a proof of the popularity of this anti-impotency medicine and how it scores above its fellow competitors like cialis and levitra.
