Introduction – Why the Once-Daily Option • Oral PDE5 inhibitors successfully treat ED1; however, • Ameliorating the full psychological impact of ED remains a challenge2 • One complication is the lack of a clear pattern of timing of sexual activity for many couples2 • Once-daily dosing would offer an alternative for couples who prefer spontaneous instead of scheduled sexual activities, or for those who anticipate frequent sexual activities ED=erectile dysfunction; PDE5=phosphodiesterase 5 1. Eardley I et al. J Sex Med 2010;7:524-40. 2. Fisher W et al. J Sex Med 2005;2:675-84.
Introduction – Why the Once-Daily Option • Dosing paradigms that eliminate coordinating dosing with sexual activity are desirable to accommodate individual patterns and spontaneity of sexual intimacy1-3 • Tadalafil is suited for use as a once-daily ED therapy, owing to its long half-life (17.5 hours)4 ED=erectile dysfunction; PDE5=phosphodiesterase 5 1.

Tadalafil Pharmacokinetics and Once-Daily Dosing • The mean half-life of tadalafil is 17.5 hours1,2 • Steady-state plasma concentrations are attained within5 days of daily dosing • Exposure is approximately 1.6-fold greater than after a single dose3: • Daily tadalafil 10 mg 16 mg at steady state • Daily tadalafil 5 mg 8 mg at steady state • This duration of efficacy may permit men with ED and their partners to disconnect sexual activity from dosing ED=erectile dysfunction 1.

Tadalafil OAD: Reliability of Efficacy • A pooled retrospective analysis of the two general ED OAD registration studies1,2 for the initial 12 weeks of either study examined first-attempt success rate and the reliability of response* in men treated with tadalafil 2.5 mg OAD (n=96) or 5 mg OAD (n=206) versus placebo (n=148)3 • Cumulative proportion of men with intercourse success (“Yes” to SEP3) at any time (to Week 12) by number of attempts was also calculated *Defined as rate of intercourse success (following successful attempt) per Sexual Encounter Profile Question 3 (SEP3): “Did your erection last long enough for you to have successful intercourse?” after a successful attempt ED=erectile dysfunction; OAD=Once-a-Day or Once-Daily 1.

Tadalafil Once-Daily Efficacy Summary • Once-daily tadalafil improved erectile function by IIEF EF domain in general ED placebo-controlled studies (2.5 mg or 5 mg)1,2as well as in 1- and 2-year open-label studies (5-mg only)3 • Onset of efficacy of tadalafil 2.5 mg or 5 mg OAD within a few days (Day 2 or Day 3) of initiating therapy has been demonstrated1-2,4 • Reliability: Over 12 weeks and post initial success, more men on tadalafil 5 mg OAD (85.9%; p<0.001) had subsequent success than placebo (70.2%)5 ED=erectile dysfunction; IIEF EF=International Index of Erectile Function Erectile Function Domain; OAD=Once-a-Day or Once-Daily 1.

Tadalafil Once-Daily Safety and Tolerability Summary • Most patients completed open-label extensions of the two once-daily studies in the general erectile dysfunction population (208/234 [1-year extension]; 139/238 [2-year extension]) • Incidence and type of adverse events was similar for tadalafil once-daily 5 mg (24 months) and on-demand 5/10/20 mg (24 months) • No events suggestive of drug-related toxicity on tests of visual function were evident with 6 months’ daily treatment • Incidence of cardiovascular adverse events was low, and comparable for tadalafil- and placebo-treated patients
