The eve of the FDA hearing for Uprima (TAP Pharmaceuticals)---the second oral agent for male erectile dysfunction---scheduled for 4/10/2000, finds the following usage data for Viagra:

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.
