          Abstract

          Erectile dysfunction (ED) is often perceived by both patients and sexual partners as a serious problem that can jeopardize quality of life, psychosocial or emotional well-being, and the partnership in the long term. Since their introduction, oral phosphodiesterase type 5 inhibitors (PDE5Is) have been found to be highly effective and well tolerated, and are available as the first-line therapy for the treatment of ED. Udenafil is one of the selective PDE5Is made available in recent years for the treatment of ED. Udenafil has clinical properties of both relatively rapid onset and long duration of action due to its pharmacokinetic profile, thereby providing an additional treatment option for ED men to better suit individual needs. There is positive evidence that udenafil is effective and well tolerated in the treatment of ED of a broad spectrum of etiologies or severity. Udenafil is as effective in the treatment of diabetes mellitus-associated ED as other PDE5Is. Due to the clinical property of relatively long duration of action, udenafil may be another option in daily dosing treatment for ED, as suggested by its favorable efficacy and safety profile. Most adverse effects reported from clinical trials are mild or moderate in severity, without any serious adverse event, with headache and flushing being the most common. Also, the concomitant use of anti-hypertensive drugs or alpha-1-blockers does not significantly affect the efficacy and safety profile of udenafil. However, additional studies with larger cohorts including prospective, multicenter, comparative studies with patients of different ethnicities are needed to further validate the favorable findings of udenafil in the treatment of ED.

            Comparative effectiveness and safety of oral phosphodiesterase type 5 inhibitors for erectile dysfunction: a systematic review and network meta-analysis.

            Phosphodiesterase type 5 inhibitors (PDE5-Is) are currently the first-line therapy for erectile dysfunction (ED), but available studies investigating the comparative effects of different PDE5-Is are limited.

              Association between erectile dysfunction and coronary artery disease. Role of coronary clinical presentation and extent of coronary vessels involvement: the COBRA trial.

              To investigate the prevalence of erectile dysfunction (ED) in patients with CAD according to clinical presentation, acute coronary syndrome (ACS) vs. chronic coronary syndrome (CCS), and extent of vessel involvement (single vs. multi-vessel disease). 285 patients with CAD divided into three age-matched groups: group 1 (G1, n=95), ACS and one-vessel disease (1-VD); group 2 (G2, n=95), ACS and 2,3-VD; group 3 (G3, n=95), chronic CS. Control group (C, n=95) was composed of patients with suspected CAD who were found to have entirely normal coronary arteries by angiography. Gensini's score used to assess extent of CAD. ED as any value <26 according to the International Index of Erectile Function (IIEF). ED prevalence was lower in G1 vs. G3 (22 vs. 65%, P<.0001) as a result of less atherosclerotic burden as expressed by Gensini's score [2 (0-6) vs. 40 (19-68), P=0.0001]. Controls had ED rate values similar to G1 (24%). Group 2 ED rate, IIEF, and Gensini's scores were significantly different from G1 [55%, P<0.0001; 24 (17-29), P=0.0001; 21 (12.5-32), P<0.0001] and similar to G3 suggesting that despite similar clinical presentation, ED in ACS differs according to the extent of CAD. No significant difference between groups was found in the number and type of conventional risk factors. Treatment with beta-blockers was more frequent in G3 vs. G1 and G2. In G3 patients who had ED, onset of sexual dysfunction occurred before CAD onset in 93%, with a mean time interval of 24 [12-36] months. In logistic regression analysis, age (OR=1.1; 95% confidence interval (CI), 1.05-1.16; P=<0.0001), multi-vessel vs. single-vessel (OR=2.53; 95% CI, 1.43-4.51; P=0.0002), and CCS vs. ACS (OR=2.32; 95% CI, 1.22-4.41; P=0.01) were independent predictors of ED. ED prevalence differs across subsets of patients with CAD and is related to coronary clinical presentation and extent of CAD. In patients with established CAD, ED comes before CAD in the majority by an average of 2 up to 3 years.
