Selected AbstractsORIGINAL RESEARCH,ED PHARMACOTHERAPY: Sildenafil Citrate 100 mg Starting Dose in Men with Erectile Dysfunction in an International, Double-Blind, Placebo-Controlled Study: Effect on the Sexual Experience and Reducing Feelings of Anxiety About the Next Intercourse AttemptTHE JOURNAL OF SEXUAL MEDICINE, Issue 10 2009Oleg B. Loran MD ABSTRACT Introduction., Sildenafil citrate 50 mg is the recommended starting dose for men with erectile dysfunction (ED); however, most men are later titrated to sildenafil 100 mg for improved efficacy. Aim., Assess the tolerability and efficacy of sildenafil initiated at the 100-mg dose in men with ED. Methods., Men with ED (score ,25 on the Erectile Function domain of the International Index of Erectile Function) who had received ,6 total doses of a phosphodiesterase type 5 inhibitor and none within 4 weeks were randomized to 8 weeks of double-blind, placebo-controlled (DBPC), fixed-dose treatment (50 or 100 mg sildenafil or placebo) followed by 4 weeks of open-label flexible-dose sildenafil (50 or 100 mg). Main Outcome Measures., Efficacy, tolerability, treatment satisfaction, and other end points were measured at baseline and/or the end of the double-blind and open-label phases and compared between placebo and sildenafil initiated at doses of 50 and 100 mg. Results., Improvements in DBPC patient-reported outcomes from baseline were statistically significant for both sildenafil 50 and 100 mg compared with placebo. At the end of DBPC treatment, 56% of men on the 100-mg dose felt no anxiety about the next intercourse attempt compared with 39% in the 50-mg group (odds ratio 2.03; P = 0.0197). Changes in functional scores from baseline were not statistically significant with the 100-mg dose compared with the 50-mg dose in the DBPC. Measures of treatment satisfaction and sexual experience significantly favored the 100-mg dose compared with the 50-mg dose in the DBPC. There was no increase in adverse events with the higher dose. Conclusions., Sildenafil at 50 mg or 100 mg significantly improved erection quality, treatment satisfaction, anxiety levels, and the sexual experience compared with placebo during DBPC. Sildenafil 100 mg improved the sexual experience and treatment satisfaction, and reduced feelings of anxiety compared with the 50-mg dose.

[source] Timing of Dose Relative to Sexual Intercourse Attempt in Previous Sildenafil Citrate Users Treated with Tadalafil: A Geographical Comparison from a Single Arm, Open-Label StudyTHE JOURNAL OF SEXUAL MEDICINE, Issue 10 2009Eusebio Rubio-Aurioles MD ABSTRACT Introduction., Previous research has demonstrated that sildenafil citrate users alter dosing-sexual attempt behavior when switched to tadalafil. The impact of geography and culture on sexual behavior with phosphodiesterase type 5 (PDE5) inhibitor treatment has not been fully investigated. Aim., To describe and compare the changes in dosing-sexual attempt behavior with sildenafil citrate vs. tadalafil treatment across four distinct geographies: Asia, Australia/New Zealand (ANZ), Central Eastern Europe/Middle East (CEE/ME), and Latin America (LA). Methods., Data from a single-arm, open-label clinical trial conducted in 21 countries from November 2002 to May 2004 were used in this analysis. Men with erectile dysfunction and a history of ,6-week prior sildenafil citrate use continued sildenafil citrate treatment for 4 weeks then switched to tadalafil for 8 weeks. Dosing instructions were provided. Main Outcomes Measures., Timing of dose and sexual intercourse was assessed through patient diaries for the final 4 weeks of each treatment period. Results., A total of 2,760 men were enrolled: Asia 15.8%; ANZ 29.4%; CEE/ME 19.7%; LA 35.1%. The median time from dosing to intercourse was significantly increased during tadalafil treatment across all geographical regions; however, the magnitude of increase differed significantly by geography (P < 0.0001). The Asian cohort demonstrated the shortest duration between dosing and sexual intercourse attempts (irrespective of drug), and altered sexual behavior the least upon switching to tadalafil. The ANZ cohort demonstrated the longest duration between dosing and sexual intercourse attempts (irrespective of drug), and altered sexual behavior the most upon switching to tadalafil. Conclusion., Men with a history of established sildenafil citrate use alter their dose-attempt behavior when treated with tadalafil irrespective of geography. However, the extent to which sexual behavior alters is not uniform across geographical regions, suggesting that dosing instructions and duration of drug effectiveness, in combination with personal and cultural preferences, may determine sexual behavior with PDE5 inhibitor use.

[source] Efficacy and safety of on-demand tadalafil for the treatment of erectile dysfunction in South-East Asian menINTERNATIONAL JOURNAL OF UROLOGY, Issue 6 2006YING LU GUO Aim:, Tadalafil is an inhibitor of phosphodiesterase type 5 used for the treatment of erectile dysfunction (ED). The efficacy and safety of tadalafil have been evaluated extensively in Western populations. Our aim was to assess the efficacy and safety of on-demand tadalafil for the treatment of ED in South-East Asian men. Methods:, This was a randomized, double-blind, placebo-controlled study of men with mild to severe ED of various etiologies randomized to receive placebo (n = 122), tadalafil 10 mg (n = 120), or tadalafil 20 mg (n = 125), taken as needed (maximum once daily) for 12 weeks. Efficacy assessments included the International Index of Erectile Function (IIEF), the Sexual Encounter Profile (SEP) diary, and a Global Assessment Question (GAQ). Results:, Men from China, Singapore, and the Philippines participated in this trial (n = 367). Compared with placebo, tadalafil significantly improved erectile dysfunction on all efficacy outcomes (P < 0.001). Patients receiving tadalafil 10 mg and 20 mg experienced a significant mean improvement of 8.1 and 8.7, respectively, in the IIEF Erectile Function (IIEF-EF) domain score from baseline (vs placebo 2.4, P < 0.001). In patients receiving tadalafil 10 mg and 20 mg, the mean per-patient success rate for intercourse attempts (SEP3) was 62% and 70%, respectively, compared with 32% for the placebo group (P < 0.001). Of patients who received tadalafil 10 mg and 20 mg, 81% and 86% reported improved erections at endpoint (GAQ) compared with 44% in the placebo group (P < 0.001). The most common adverse events reported by patients were headache, back pain, dyspepsia, and dizziness. Conclusions:, Tadalafil was an effective and well-tolerated treatment for South-East Asian men with ED.

[source] Efficacy and Safety of Oral Tadalafil in the Treatment of Men in Canada with Erectile Dysfunction: A Randomized, Double-Blind, Parallel, Placebo-Controlled Clinical TrialTHE JOURNAL OF SEXUAL MEDICINE, Issue 5 2005FRCSC, Serge Carrier MD ABSTRACT Introduction., Erectile dysfunction (ED) is a highly prevalent, often undertreated condition. Aim., This 12-week, double-blind, parallel, placebo-controlled study was conducted at 25 sites in Canada to evaluate the efficacy and safety of oral tadalafil, a phosphodiesterase type 5 inhibitor, for the treatment of ED. Methods., Men with ED of organic, psychogenic, or mixed etiology were stratified by baseline ED severity then randomly assigned to placebo (N = 50), tadalafil 10 mg (N = 103), or tadalafil 20 mg (N = 100), taken as needed (maximum, once daily). Main Outcome Measures., Efficacy was assessed by the International Index of Erectile Function (IIEF), a Sexual Encounter Profile diary, and a global assessment question (GAQ). Results., Tadalafil 10 mg and tadalafil 20 mg significantly improved erectile function compared with placebo (P < 0.001, all measures). At end point, the mean IIEF erectile function (EF) domain scores were 14.5, 21.2, and 23.3 of a possible score of 30 for placebo, tadalafil 10 mg, and tadalafil 20 mg, respectively. Patients treated with tadalafil reported greater change from baseline on the IIEF EF domain score compared with placebo, regardless of baseline ED severity. During treatment, the mean per-patient proportion of successful intercourse attempts was higher for tadalafil 10 mg and 20 mg than for placebo (placebo, 31.9%; tadalafil 10 mg, 56.7%; and tadalafil 20 mg, 61.5%), and a greater proportion of patients reported improved erections with tadalafil (GAQ; placebo, 22.0%; tadalafil 10 mg, 67.0%; tadalafil 20 mg, 79.0%). Fifty percent and 62% of patients treated with tadalafil 10 mg and 20 mg, respectively, achieved successful sexual intercourse after their first dose, compared with 31% with placebo. Treatment-emergent adverse events were generally mild or moderate. Conclusion., Tadalafil was an effective, well-tolerated therapy for ED of broad-spectrum etiology and severity.

ABSTRACT Introduction., Tadalafil is a phosphodiesterase type 5 inhibitor for the treatment of erectile dysfunction (ED). Past clinical trials have assessed its efficacy and safety in western populations. Tadalafil has not been investigated in a large clinical trial with a South-east Asian population. Aim., To assess the efficacy and safety of on-demand tadalafil for the treatment of ED in a 12-week, double-blind, placebo-controlled study in Taiwan. Methods., Men with mild to severe ED of various etiologies were randomized to receive placebo, tadalafil 10 mg, or tadalafil 20 mg, taken as needed (maximum once daily). Efficacy assessments included the International Index of Erectile Function, the Sexual Encounter Profile (SEP) diary, and a Global Assessment Question (GAQ). Results., Tadalafil significantly improved erectile function compared with placebo (P < 0.005, all measures). At endpoint, the patients receiving tadalafil reported a greater mean per-patient percentage of successful intercourse attempts (SEP question 3: 70.0%, 10 mg; 78.0%, 20 mg) than placebo-treated patients (42.8%) and a greater proportion of improved erections (GAQ: 92.3% and 84.6% vs. 54.5%). Most treatment-emergent adverse events were mild or moderate. The most common adverse events were back pain, dyspepsia, and myalgia. Conclusions., Tadalafil was an effective, well-tolerated therapy for men in Taiwan with ED of broad-spectrum severity and etiology. [source] A double-blind placebo-controlled study of the efficacy and safety of pentoxifylline in early chronic Peyronie's diseaseBJU INTERNATIONAL, Issue 2 2010Mohammad Reza Safarinejad Study Type , Therapy (RCT) Level of Evidence 1b OBJECTIVE To analyse the safety and efficacy of pentoxifylline sustained-release (PTX-SR) treatment in patients with early chronic Peyronie's disease (PD). PATIENTS AND METHODS In all, 228 patients with a mean (sd) age of 51 (9) years who had early chronic PD were randomized to receive 400 mg PTX-SR (Apo-Pentoxifylline, Apotex Inc., Toronto, Canada) twice daily (group 1, 114) or similar regimen of placebo (group 2, 114) for 6 months. A medical history was taken and the men had a complete physical examination. The following variables were assessed before and after therapy: penile curvature and penile artery spectral traces (end-diastolic velocity, EDV, peak systolic velocity, PSV, and resistivity index, RI, of the right and left cavernous arteries assessed with dynamic penile duplex ultrasonography), plaque characteristics (assessed by penile X-ray and penile ultrasonography), pain (assessed by visual analogue scale), erectile function (assessed by the International Index of Erectile Function, IIEF questionnaire), treatment satisfaction (assessed by Erectile Dysfunction Inventory of Treatment Satisfaction questionnaire), and side-effects. Patient perception of penile curvature and plaque size, and mean weekly intercourse attempts were also assessed. RESULTS Overall, 36.9% of patients who received PTX-SR reported a positive response, vs only 4.5% in the placebo group. Of patients in PTX-SR group, 12 (11%) had disease progression, vs 46 (42%) in placebo group (P = 0.01). Improvement in penile curvature (P = 0.01), and plaque volume (P = 0.001) was significantly greater in patients treated with PTX-SR than placebo. The increase in IIEF total score was significantly higher in the PTX-SR group (P = 0.02). Mean PSV changes after therapy compared to baseline were statistically significant between PTX-SR (right, +11.4%, left, +11.7%) and placebo-treated (+0.2% and ,4.2%, respectively) patients (both P = 0.04). CONCLUSIONS PTX-R was moderately effective in reducing penile curvature and plaque volume in patients with early chronic PD. Further studies with different treatment regimens are needed to better elucidate the beneficial effects of PTX-SR in PD. [source] | ||||||||||
