Lilly ICOS Enjoys Early Success For Cialis(R) in ED Marketplace, Surpasses
Levitra(R) in New U.S. Prescriptions
- Recent Head-to-Head Clinical Studies Indicated Patients Prefer Cialis -
BOTHELL, Wash. and INDIANAPOLIS, March 23 /PRNewswire-FirstCall/ -- After only
three months on the U.S. market, Lilly ICOS's erectile dysfunction (ED) drug
Cialis(R) (tadalafil) has already captured a significant share of new
prescriptions, beating Levitra(R) (vardenafil HCl) and further eroding the U.S.
share of market for Viagra(R) (sildenafil citrate). Cialis is the only oral ED
treatment on the market that has been shown to improve erectile function up to
36 hours in most men.
For three weeks running, Cialis has surpassed Levitra in share of new
prescriptions written in the United States. For the week ending March 12,
Cialis captured 18.1 percent of new prescriptions compared to Levitra's 15.4
percent.(1)
"Cialis is the fastest growing oral ED treatment on the market; with its rapid
uptake we are clearly seeing that men are interested in the distinctive benefits
the brand offers," said Paul Clark, Chairman and CEO of ICOS Corporation. "And,
we are encouraged that our strategy for communicating about Cialis to healthcare
professionals and consumers is working with both audiences."
The success of Cialis in the U.S. market is supported by recently published data
in European Urology that showed that 73 percent of men preferred Cialis to
Viagra for treatment of their ED after receiving treatment with both
products.(2) Further, an independent head-to-head trial also showed patient
preference for Cialis over both Levitra and Viagra.
"The progress we have made in just three short months, along with the newly
available published and independent clinical data, supports our long-standing
belief that Cialis is an attractive treatment for ED," said Gino Santini,
President, U.S. Operations, Eli Lilly and Company. "Cialis is the only oral ED
treatment that gives couples up to 36 hours to choose the moment for intimacy
that is right for them."
