Penetration and maintenance of erection with vardenafil: a time-from-dosing analysis.
Canadian Journal of Urology 2005 June
OBJECTIVE: To assess success rates in ability to penetrate (Sexual Encounter Profile question 2 [SEP2]) and maintain erections to completion of intercourse (SEP3) from time of dosing to start of sexual activity in a retrospective analysis of two pivotal trials.
METHODS: In two randomized, double-blind studies, men with ED for > 6 months received vardenafil 5 mg, 10 mg, or 20 mg or placebo for 12-26 weeks. Patients were instructed to start sexual activity 1 hour after dosing. In this retrospective pooled analysis, patient diary questions through week 12 were analyzed, providing attempt data was recorded 0-12 hours post-dose. Mean per-patient SEP2 and SEP3 success rates (intent-to-treat population) were calculated by time between dosing and start of sexual activity, from 0-12 hours through week 12. Least-square means and nominal p-values for differences versus placebo were derived by analysis of covariance with terms for baseline, study and treatment.
RESULTS: Most attempts at sexual intercourse occurred 30-90 minutes after dosing: 88%-93% of attempts occurred within 120 minutes. SEP2 success rates in patients choosing to attempt sexual activity in each interval from < or = 15 minutes through the 4-8-hour interval were higher with vardenafil compared with placebo, while SEP3 success rates were greater with vardenafil for patients choosing to initiate sexual activity from < or = 15 min through the 8-12-hour interval. The most commonly reported treatment-emergent adverse events in patients receiving vardenafil included headache (11%-22%), flushing (6%-13%), rhinitis (5%-13%), and dyspepsia (2%-7%).
CONCLUSION: In this retrospective analysis of two pivotal trials, vardenafil improved success rates compared with placebo in ED patients who attempted intercourse from as early as 15 minutes or less and through 4-8 hours after dosing in ability to penetrate (SEP2) and from as early as 15 minutes or less and through 8-12 hours after dosing in maintenance of erection (SEP3).
