Vardenafil works for 10 hours

Vardenafil (Levitra) is effective for up to 10 hours after administration, results presented at the World Congress of Sexology in Montreal earlier this month have shown. A study of 383 men with erectile dysfunction showed that vardenafil taken six to 10 hours before intercourse led to a penetration success rate of 81 per cent, compared with 51 per cent for placebo, and a maintenance of erection success rate of 70 per cent, compared with 34 per cent for placebo.
