Effectiveness of Levitra and Levitra Studies

In the first study, men with erectile dysfunction who were taking the oral investigational drug Levitra™ reported consistently improved erectile function the first time they took the drug and subsequently thereafter. For the three months of the study involving more than 800 ED patients, Levitra™ was reported to consistently improve rates of successful penetration, intercourse success and overall satisfaction during the first and subsequent attempts.

Investigators evaluated the ability of Levitra™ to provide reliable efficacy over time in a broad population of men with ED. They analyzed data from a phase III, randomized, double-blind study in which 805 men, including 100 Canadian men with ED and 11 Canadian trial sites, received Levitra™ 5, 10 or 20 mg or placebo for up to 26 weeks.

Results

The analysis showed that at a 20 mg dose of Levitra™: On average men were successful in 74 per cent of their first attempts in penetrating their partner compared with 46 per cent of men taking placebo. Of those men taking Levitra™ who were successful the first time, they continued to achieve successful penetration in 91 per cent of subsequent attempts.

“Men want to be confident that the ED drug they are taking works the first time and time after time,” said Dr. Luc Valiquette, Professor of Urology at the Hospital Saint-Luc du CHUM in Montreal, Quebec. “I’ve seen frustration in some of my patients because the current treatments do not consistently work, and their efficacy may diminish over time. This reinforces the need for new oral ED therapies that are effective, consistent and safe.”
