Evaluation of the Efficacy and Safety of Once-a-Day Dosing of Tadalafil 5mg and 10mg in the Treatment of Erectile Dysfunction: Results of a Multicenter, Randomized, Double-Blind, Placebo-Controlled Trial

Torres, Dr. Luiz F.

Bottom line

In conclusion, once-a-day dosing with tadalafil 5 and 10mg significantly improved EF versus placebo, and patients were highly compliant with this dosing regimen. Adverse events reported by patients tended to be mild or moderate in severity, and the rate of discontinuations caused by adverse events was similar to rates seen in studies that used on-demand dosing. Therefore, once-a-day dosing with tadalafil may be an attractive alternative to on-demand therapy for ED. These data have been reported previously in abstract form: Giuliano F, Porst H, Shen W, Chang S. 2002.

Tadalafil belongs to a group of medicines called phosphodiesterase 5 (PDE5) inhibitors. These medicines prevent an enzyme called phosphodiesterase type-5 from working too quickly. The penis is one of the areas where this enzyme works.

The incidence rate of MI for these 35 studies was 0.33 per 100-patient years (n=10,460 patients, 5,088 patient-years exposure to tadalafil). This rate is no higher than MI rates in placebo-treated patients (0.41 per 100 patient-years; n=2,118; 489 patient-years), or in an age-standardized male population (0.6 per 100 patient-years) [24]. Chronic dosing of PDE5 inhibitors may have medical benefits beyond ED. Chronic administration of PDE5 inhibitor therapy is efficacious in the treatment of pulmonary arterial hypertension [25] and may have cardioprotective effects for ischemia-reperfusion injury [26]. A daily approach also may improve organic ED at the level of vascular endothelial function.

Usual Adult Dose for:

Recent data suggest both sildenafil and tadalafil could exert prolonged beneficial effects on vascular endothelial function if taken regularly [27–30]. In this context, the FDA recently approved sildenafil citrate 20mg (Revatio®) at three times per day for the indication of primary pulmonary hypertension. This suggests that daily use of PDE5 inhibitors may have further potential for non-ED and ED indications. The interpretation of our results is subject to limitations. First, patients with an IIEF EF domain score ≥26 were included in the primary analysis, which is consistent with clinical practice; most clinicians do not administer the IIEF.

Maximum Dose of Tadalafil

Exclusion of patients with “no ED” increased the magnitude of change from baseline but did not affect the statistical interpretation of the data. Therefore, including these patients may be the more conservative analysis. Whether daily dosing with tadalafil could rescue nonresponders is unknown, because patients with prior tadalafil in women experience with tadalafil and patients who were sildenafil nonresponders were not included in this study. Third, because this study did not compare once-a-day dosing with on-demand dosing or every-other-day dosing, we cannot adequately compare the efficacy and tolerability of the regimens or comment on which would be preferred, but the efficacy and tolerability of 5mg tadalafil taken daily appear to be comparable to the efficacy and tolerability of 20mg taken on demand or every other day. Further studies that address this comparison could be useful for clinicians. Erectile dysfunction is a condition where the penis does not harden and expand when a man is sexually excited, or when he cannot keep an erection. When a man is sexually stimulated, his body's normal response is to increase blood flow to his penis to produce an erection. By controlling the enzyme, tadalafil helps to maintain an erection after the penis is stroked by increasing blood flow to the penis. Without physical action to the penis, such as that occurring during sexual intercourse, tadalafil will not work to cause an erection.

What other information should I know?

Tadalafil taken on demand is efficacious 30 minutes to 36hours after dosing [10]. In most cases, men are able to respond after the first dose, though for some men who need the greatest plasma levels of tadalafil, these would be achieved after the first few days of dosing. Further studies that address this point could be useful for clinicians. Recently, every-other-day dosing with tadalafil 20mg has been investigated [13] The efficacy results for every-other-day dosing are comparable with on-demand and once-a-day dosing, and 42% of men preferred every-other-day dosing. Although McMahon reported 72% of patients preferred daily dosing, once-a-day administration of 10mg (or 5mg) is scientifically difficult to compare with every-other-day administration of 20mg without a cross-over study.

However, since every-other-day dosing was efficacious, and nearly half the men preferred this regimen, every-other-day dosing with tadalafil may be another alternative regimen. In this study, both doses of tadalafil were well tolerated when taken daily. This is corroborated by both the high rate of treatment compliance and the low frequency of discontinuation caused by adverse events. The discontinuation rate in this study (3.4%) is numerically similar to that seen in on-demand studies (tadalafil 10/20mg; 1.6%–5.5%) [9,10,19–22] and in a long-term (18–24 months) study (tadalafil 5/10/20mg 6.3%) [23]. The incidence of adverse events in this study was similar to that seen in the pooled analysis of 11 on-demand studies.

The profile of adverse events also was similar, although with a possible reduction in headache (6.4%–10.5% versus 12%–15% in the 11 pooled studies, and 15.8% in the long-term study) [9,23]. However, given the broad differences between the studies, direct comparisons should be interpreted with caution. The McMahon once-a-day dosing studies reported two [18] and four [12] incidents of MI, all in patients with significant multiple vascular risk factors. All were determined to not be drug related [18]. The MI rates reported by McMahon are inconsistent with incidence rates of MI recorded in 35 clinical trials of tadalafil, which included four studies of daily dosing with tadalafil and 371 patient-years of exposure.
