IC351 (Cialis) is a selective inhibitor of PDE5. The efficacy and safety of on-demand dosing of IC351 in men with erectile dysfunction was assessed in a multicenter, double-blind, placebo-controlled study. One hundred seventy-nine men (mean age: 56 y) were randomized to receive placebo or IC351 at doses of 2, 5, 10 or 25 mg, taken on demand over a 3-week period. The primary endpoints were change from baseline in responses to Questions 3 (Q3) and 4 (Q4) of the International Index of Erectile Function (IIEF). IC351 significantly improved IIEF Q3 scores at all doses vs placebo (P < or =0.003). IC351 also significantly improved IIEF Q4 scores in all but the 2 mg group (P < or =0.0003). No significant changes in laboratory values, ECGs, or blood pressure were observed. The most common adverse events were headache and dyspepsia. The conclusion of this study was that on-demand IC351 at doses up to 25 mg was well tolerated and significantly improved erectile function.

IC351 (tadalafil, trade name Cialis) is a new representative compound of the second generation of selective phosphodiesterase 5 (PDE-5) inhibitors. The selectivity ratio vs PDE-5 is more than 10 000 for PDE-1 through PDE-4 and PDE-7 through PDE-10 and 780 for PDE-6. In the European daily-dosing trial, the efficacy rates were up to 93% for successful intercourses with completion in the 50-mg dose in patients with mild to moderate erectile dysfunction (ED). In two different dose-ranging studies with 2-25 mg taken as needed, efficacy rates of up to 88% improvement in erections and up to 73% successful intercourses with completion were achieved. In a placebo-controlled, fixed-dose (10- and 20-mg) trial in diabetic patients, improved erections of 56% and 64% were reported compared with 25% after placebo. Drug-related adverse effects, with headache in up to 23% of patients (placebo, up to 17%), dyspepsia in up to 11% (placebo, up to 7%), back pain in up to 4.7% (placebo, 0%), and myalgia in up to 4.1% (placebo, up to 2.4%), were mostly mild to moderate. Neither drug-related serious cardiovascular adverse events nor color vision disturbances were encountered. The long half-life (>17 h), with a comfortably long window of opportunity, releases couples from the need to plan sexual activities and therefore provides the highest amount of spontaneity for sexual activities.

black triangle Tadalafil is a selective phosphodiesterase type 5 inhibitor that is effective in men with mild-to-severe erectile dysfunction (ED), including those with diabetes mellitus. black triangle The improvement in the erectile function domain score on the International Index of Erectile Function (IIEF) and the percentage of sexual intercourse attempts marked by successful vaginal penetration and completion was significantly greater with on-demand (not more than once daily) tadalafil 10 or 20 mg than placebo in trials of 12 weeks' duration. Improvement in scores on other domains of the IIEF and the percentage of positive responses to a Global Assessment Question measuring erection improvement were also significantly greater with on-demand tadalafil than placebo. black triangle The adverse events associated with tadalafil were generally mild to moderate and decreased in frequency with continued administration. The most commonly reported adverse events were headache and dyspepsia. The incidence of cardiovascular adverse events was not significantly different in tadalafil or placebo recipients.

Advances in molecular biology and protein chemistry, along with increasing understanding of the mechanisms of penile erection, have spurred development of pharmacologic approaches to the treatment of erectile dysfunction (ED). The next generation of oral agents includes tadalafil, a potent, highly selective phosphodiesterase 5 inhibitor. In vitro studies have shown that tadalafil enhances relaxation of trabecular smooth muscle, and clinical trials have supported its efficacy and tolerability in a broad population of men with ED. The effect of tadalafil in enhancing the erectile response to sexual stimulation is relatively rapid in onset and lasts for >or=24 hours. The ability of patients with ED treated with tadalafil to achieve improved erectile function is demonstrated by significantly increased subjective measures of penetration ability, successful intercourse, and sexual satisfaction. Partners have expressed similar or higher levels of satisfaction with the results of treatment. Men with ED of psychogenic, organic, or mixed etiology and in a range from mild to severe have experienced significant improvment with tadalafil treatment. Response to treatment in men with diabetes has been robust and not affected by disease severity. Tadalafil has been well tolerated. Adverse events have generally been mild or moderate and have abated with continued treatment. Headache and dyspepsia have been most frequently reported. Changes in color vision have been rare (<0.1%) with tadalafil across all clinical trials. Tadalafil appears to be a safe and effective treatment for men with ED.

Erectile dysfunction (ED) affects up to 50% of men, between 40 and 70 years of age. In the first major trial of sildenafil in ED, at 24 weeks, improved erections were reported by 77 and 84% of men taking sildenafil 50 and 100mg, respectively. Subsequently, sildenafil has been reported to be effective in men with ED associated with diabetes and prostate cancer, and in psychogenic ED. Sildenafil is safe in men with coronary artery disease, provided it is not used with the nitrates (a contraindication). The most commonly reported adverse effects with sildenafil are headache, flushing and dyspepsia. Vardenafil is more potent and more selective than sildenafil at inhibiting phosphodiesterase-5. Vardenafil is similarly effective to sildenafil in the treatment of ED. The only advantage that vardenafil has over sildenafil is that it does not inhibit phosphodiesterase-6 to alter colour perception, a rare side effect which sometimes occurs with sildenafil. Tadalafil has a longer duration of action than sildenafil and vardenafil. Tadalafil is similarly effective as sildenafil in the treatment of ED. In comparison studies, tadalafil is preferred to sildenafil (50/100mg) by men with ED, possibly because of its longer duration of action. Of the phosphodiesterase inhibitors, tadalafil may displace sildenafil as the drug of choice among men with ED.

The efficacy and safety of tadalafil for the treatment of erectile dysfunction (ED) were assessed in a 6-month, randomised, double-blind, placebo-controlled study. Australian men with mild, moderate or severe ED of organic, psychogenic or mixed aetiology were randomised to tadalafil 20 mg as needed (n = 93) or placebo (n = 47). Efficacy assessments included the international index of erectile function (IIEF) and the sexual encounter profile (SEP) diary. Tadalafil significantly improved erectile function compared with placebo (p < 0.001, all measures). At the end of the study, the mean per-patient proportion of successful sexual intercourse attempts (SEP question three) was 73.5% for patients treated with tadalafil and 26.8% for placebo-treated patients. Improved erections were reported by 78% of tadalafil-treated patients compared to 12.8% of placebo-treated patients. The most common treatment-emergent adverse events--headache and dyspepsia--were generally mild or moderate. Tadalafil was effective and well tolerated in Australian men with mild to severe ED.

A multicentre, non-randomised, open-label study assessed whether personal distress caused by erectile dysfunction (ED) affected psychosocial outcomes of tadalafil treatment. Eligible Swedish men at least 18 years old reporting > or =3-month history of ED were stratified into two groups (manifest or mild/no distress) based upon a distress question administered at enrollment. Tadalafil 20 mg was taken as needed for 8 weeks. The primary outcome was the difference between the two distress groups in change from baseline in the Psychological and Interpersonal Relationship Scales (PAIRS) spontaneity domain. Secondary outcome measures were PAIRS sexual self-confidence and time concerns domains, Life Satisfaction (LiSat-11) checklist and a Global Assessment of Treatment Response. The study also assessed tolerability. Of 662 men enrolled, 88% had manifest distress and 12% had mild/no distress. Baseline-to-endpoint changes for PAIRS domains were not significantly different between groups. Baseline-to-endpoint changes in LiSat-11 items were not significantly different between groups except for satisfaction with sexual life. Compared with men without ED, below normal baseline satisfaction with partner relationship and family life were normalised at endpoint. Over 90% of men reported improved erection and ability to engage in sexual activity. The most common treatment-emergent adverse events were headache, myalgia, dyspepsia, flushing and back pain. One man discontinued because of myalgia; 630 (95%) completed the study. In conclusion, erectile distress levels vary among patients with ED and distress can affect intra-familiar aspects of life, which may have implications for clinical practise. However, distress does not appear to hinder improvement in both mechanical and psychosocial outcomes of tadalafil treatment.

The drug sildenafil (Viagra, Pfizer) and, more recently, tadalafil (Cialis, Lilly-Icos) and vardenafil (Levitra, Bayer), has drawn public attention to aphrodisiacs. The search for such substances dates back millennia. Adverse effects associated with these drugs include hypotension, tachycardia, headache, flushing, blurred vision, dyspepsia, and musculoskeletal pain. Although sildenafil has been marketed for erection of the penis, recent attention has been paid to its application for women, including enhancement of success of in vitro fertilization but also better sexual responses (increased desire, satisfaction, and orgasm) in cases of sexual disorders. Today, there is a debate on internet forums about the potential properties of sildenafil to enhance women's sexual pleasure. This laboratory was asked to analyze a 12-cm length of light brown hair submitted by a British police force following an allegation that a young female had been subjected to sexual assaults over a two-year period. The female was 15-17 years of age at the time. The alleged perpetrator was her stepfather, and there was some suspicion that drugs may have been administered to facilitate the attacks. After decontamination and segmentation (6 x 2-cm section), the specimen was analyzed by liquid chromatography coupled with tandem mass spectrometry after alkaline (pH 9.5) extraction using dichloromethane/ isopropanol/n-heptane (25:10:65, v/v/v). The limit of quantitation was 5 pg/mg. The proximal segment tested positive for sildenafil at 38 pg/mg, and all others proved negative. This was in accord with the victim's claim. In the absence of any controlled studies, it was impossible to put any quantitative interpretation on the measured concentration.

Authors resume the therapeutic employment of mineral waters, muds and baths in internistic syndromes or diseases. Mineral waters are used in the therapy of functional dyspepsia, gastro-oesophageal reflux, chronic primary stipsis, irritable bowel, biliary dyskinesias, mainly hypokinetic gallbladder and Oddi's sphincter, spasm, postcolecystectomy syndrome. The therapeutic effects of mineral waters are determined by their anion and cation content, the presence of undissociated salts and also by the presence of oligoelements. Additionally, the effects of a mineral waters are connected with physical constants: osmotic pressure and temperature. Many researches showed activity of the mineral waters on intestinal autonomic nerves and plexus (CIA), motility, exocrine, endocrine and paracrine digestive secretions and therapeutic properties belonging to evidence based medicine. Mud and bath therapy are effective in treatment of osteoarthritis. During and after mud-therapy effects on diencephalic-pituitary-adrenal axis were displayed, producing increase of endogenous opioids and cortisol. Clinical controlled trials showed significant improvement of symptoms as pain and stiffness. Inhalant therapy by sulphureous and salsojodic mineral waters improve symptoms as cough and escreate and functional indices as FEV1 in chronic obstructive pulmonary disease. The oligomineral waters are very useful in the treatment and secondary prevention of urolithiasis and of relapses of urinary stones after spontaneous expulsion, surgical treatment, stones removal by percutaneous or uretheroendoscopic treatment and lithotrypsia. Patients must drink at least 2L every day, substantially for ever. Chloruratesodic and bicarbonate mineral waters show improvement in disorders of lipidic and urate metabolism.

Previous studies established the efficacy of once-daily tadalafil for men with erectile dysfunction. However, no trial has focused on the effects of such treatment on men without previous experience using oral phosphodiesterase type 5 inhibitors. Patients were randomized (2:1) to once-daily tadalafil 5 mg (with possible down-titration to 2.5 mg; n = 146) or placebo (n = 69) for 12 weeks. Among 215 patients (mean age, 52 years), once-daily tadalafil treatment resulted in 61.7% of study participants reporting their ability to achieve and maintain erections as being much better or very much better (vs 21.7% on placebo; P < .001). Tadalafil significantly improved treatment satisfaction on the Erectile Dysfunction Inventory of Treatment Satisfaction (P < .001 vs placebo at end point) and psychosocial outcomes on the Self-Esteem and Relationship (SEAR) questionnaire (least squares mean difference in SEAR total score change from baseline, 11.8 [95% confidence interval, 5.4%-18.2%; P < .001 vs placebo]). Patients receiving once-daily tadalafil also experienced a higher proportion of daily self-reported spontaneous morning erections at end point (58.7%) compared with placebo (42.2%; P < .001 for the between-treatment difference in changes from baseline). However, no significant differences in parameters of endothelial dysfunction (including biomarkers and peripheral arterial tonometric measures) or nocturnal erections as recorded by the nocturnal electrobioimpedance volumetric assessment were observed between treatment groups. Tadalafil was well tolerated; adverse events included back pain, headache, and dyspepsia. These findings may contribute to a more comprehensive understanding of once-daily tadalafil's effects on phosphodiesterase type 5 inhibitor-naive men.
