Recent myocardial infarction or cerebrovascular accident (CVA) within the past 2 weeks - High-risk arrhythmias - Hypertrophic obstructive & other cardiomyopathies - Moderate-severe valvular disease • Intermediate-risk - Should be referred for further evaluation of cardiac status before receiving treatment - Recent myocardial infarction or cerebrovascular accident (ie within the last 2-6 weeks) - Left ventricular dysfunction or congestive heart failure (NYHA class III) - Asymptomatic but ≥3 risk factors for coronary artery disease (CAD) (excluding gender) - Moderate, stable angina - Murmur of unknown cause - Recurrent transient ischemic attacks (TIA) - Heart transplant • Low-risk - All 1st-line therapies may be considered - Asymptomatic coronary artery disease - Less than 3 risk factors for coronary artery disease (excluding gender) - Controlled hypertension - Mild, stable angina that has been evaluated &/or being treated - Post-successful coronary revascularization - Uncomplicated previous myocardial infarction - Mild valvular heart disease - Left ventricular© dysfunction or congestiveMIMS heart failure (NYHA class I or II) Not all products are available or approved for above use in all countries. Specifi c prescribing information may be found in the latest MIMS. B4 © MIMS 2019 Erectile Dysfunction (5 of 11) A NON-PHARMACOLOGICAL THERAPY Goals of erapy • Identify & treat any curable causes of erectile dysfunction • Initiate lifestyle & risk factor modifi cations • Provide education & counseling to patients & their partners Patient & Partner Education • Some men may only need reassurance that decline in sexual function is due to aging, medication or chronic ERECTILE DYSFUNCTION illnesses & is not necessarily a sign of serious illness - ey may refuse treatment • Education & reassurance may help in preventing further erectile failure due to the above causes • Discuss w/ patient & partner (if possible) the important treatment options & their associated risks & benefi ts • Cultural, religious & economic factors should be taken into consideration • e choice of treatment should be decided together by physician, patient & partner Lifestyle Modifi cation • Modifying possible risk factors may be helpful - Resolving partner relationship issues - Smoking cessation - Reduce alcohol/drug abuse - Regular exercise & weight management Treat Psychosocial Factors • Confronting depression or substance abuse • Sexual education/correction of misinformation Discontinue Off ending Medications • Many common medications may aff ect male sexual function - Eg antidepressants, antipsychotics, anti-arrhythmics, many antihypertensives, anti-androgens & steroids Sexual Counseling & Education • Encompass sex therapy, psychosocial therapy & marital therapy • May be appropriate for patient &/or partner • May be used to address & correct relationship issues, stress factors (eg work, fi nances, family, etc) • Decreased sexual drive may be due to psychologic issues & individual may benefi t from sexual therapy • Use as adjunct to other erectile dysfunction therapy to address patient’s psychological reaction to their need for erectile dysfunction treatment • Sexual counseling & education may be preferred by patients/partners because it is noninvasive & has broad applicability Vacuum Constriction Device • Negative pressure is applied to the pendulous penis causing blood to be drawn into the penis • Blood is retained in penis by elastic band placed at the base • Highly eff ective in inducing erections regardless of erectile dysfunction etiology • Only devices w/ a vacuum limiter should be used • Preferred by patients who do not want to use pharmacological therapy or in whom medication is contraindicated • Contraindicated in patients w/ bleeding disorders or on anticoagulant therapy

  • Phosphodiesterase (PDE)
    Phosphodiesterase (PDE) Phosphodiesterase (PDE) is any enzyme that breaks a phosphodiester bond. Usually, people speaking of phosphodiesterase are referring to cyclic nucleotide phosphodiesterases, which have great clinical significance and are described below. However, there are many other families of phosphodiesterases, including phospholipases C and D, autotaxin, sphingomyelin phosphodiesterase, DNases, RNases, and restriction endonucleases, as well as numerous less-well-characterized small-molecule phosphodiesterases. The cyclic nucleotide phosphodiesterases comprise a group of enzymes that degrade the phosphodiester bond in the second messenger molecules cAMP and cGMP. They regulate the localization, duration, and amplitude of cyclic nucleotide signaling within subcellular domains. PDEs are therefore important regulators ofsignal transduction mediated by these second messenger molecules. www.MedChemExpress.com 1 Phosphodiesterase (PDE) Inhibitors, Activators & Modulators (+)-Medioresinol Di-O-β-D-glucopyranoside (R)-(-)-Rolipram Cat.

ED is a serious problem affecting both the psychosocial state of the man and his partner [1]. In the ED development, the role of bad habits is great, for example, among smoking men it occurs 20% more often than among nonsmokers [2,3]. ED is associated with various comorbid conditions such as hypertension, hyperlipidemia, metabolic syndrome, lower urinary tract symptoms (LUTS) or benign prostatic hyperplasia (BPH), cardiovascular disease, psychological factors, diabetes mellitus, post-radical prostatectomy, antidepressant medication and antihypertensive drugs, etc. (Table 1).

Materials and methods Searches were carried out in four electronic databases: PubMed (until April 17th, 2017); Scopus (until April 17th, 2017); Embase (until April 17th, 2017); and Cochrane (until April 18th, 2017). The outcomes for this study are as follows: (1) Global Assessment Question (GAQ) positive response rate; (2) changes from baseline to the end of the study in Erectile Function Domain of International Index of Erectile Function (IIEF-EF); and (3) treatment-related adverse events (TRAEs). The comparative efects of PDE5I regimens were analyzed with random-efect models in a Bayes- ian Framework using the GeMTC R package. Results We identifed 1056 records, of which 15 randomized trials with 5274 patients were included. The included stud- ies covered eight kinds of PDE5I administration: avanafl PRN; mirodenafl PRN; sildenafl PRN; tadalafl PRN; tadalafl OAD; udenafl PRN; udenafl OAD; vardenafl PRN; and placebo.

  • Udenafil, a Phosphodiesterase 5 Inhibitor, Reduces Body Weight in High-Fat-Fed Mice
    pISSN: 2287-4208 / eISSN: 2287-4690 World J Mens Health 2018 January 36(1): 41-49 https://doi.org/10.5534/wjmh.17028 Original Article Udenafil, a Phosphodiesterase 5 Inhibitor, Reduces Body Weight in High-Fat-Fed Mice Seong Yul Ryu1,*, Yoon-Jung Choi2,*, So-Young Park2, Jong-Yeon Kim2, Yong-Dae Kim3, Yong-Woon Kim2 1Department of Internal Medicine, Keimyung University School of Medicine, Departments of 2Physiology and 3Otolaryngology, Yeungnam University College of Medicine, Daegu, Korea Purpose: High-fat (HF) feeding induces hypothalamic leptin resistance via the activation of toll-like receptor 4 (TLR4). TLR4 deficiency confers resistance to diet-induced obesity. Udenafil, an anti-impotence drug, inhibits TLR4 in airway epithelial cells in vitro. In this study, we evaluated whether udenafil suppressed the hypothalamic expression of TLR4 and reduced body weight. Materials and Methods: The hypothalamic expression of TLR4, phosphodiesterase 5 (PDE5), nuclear factor-κB (NF-κB), and myeloid differentiation primary response gene 88 (Myd88) was analyzed by real-time polymerase chain reaction after treating mice for 2 days with udenafil (0, 12, 120, or 600 μg/d). Furthermore, the hypothalamic expression of TLR4, pro-opiomelanocortin (POMC), and neuropeptide Y (NPY) was analyzed after 9 days’ treatment with udenafil and/or leptin. We also measured body weight and food intake following 9 days of udenafil and/or leptin treatment in control- and HF-fed mice. Results: Udenafil suppressed hypothalamic TLR4 mRNA expression dose-dependently. The changes were associated with decreased PDE5, NF-κB, and Myd88 expression. Udenafil treatment for 9 days reduced body weight and caloric intake in HF-fed mice.

The outcomes and complications analyzed involved the Global Efficacy Question (GEQ), sexual encounter profile diary question 2 and 3 (SEP2 and SEP3) and adverse events. All statistical analysis was performed using Stata 12.0 software (Stata Corp., College Station, TX, USA). Results: Six publications were used in analysis, including six randomized controlled trials that compared PDE5 inhibitors with placebo. Compared with placebo, PDE5 inhibitors were associated with significant improvements in GEQ (OR 11.997, 95% CI 8.073–17.830, Po0.0001), SEP2 (RR 1.847, 95% CI 1.561–2.185, Po0.0001) and SEP3 (RR 2.738, 95% CI 2.084–3.598, Po0.0001). Despite significant greater incidences of some adverse events observed (headache: RR 3.717, 95% CI 2.309–5.982, Po0.0001; flushing: RR 9.281, 95% CI 2.858–30.147, Po0.0001; gastrointestinal discomfort: RR 9.064, 95% CI 2.116–38.827, P = 0.003), most adverse events were mild to moderate and transient.
