西地那非治疗患有心血管疾病的男性勃起功能障碍患者的疗效和安全性

男性心血管疾病患者较一般人群更易患勃起功能障碍(ED),因为此两种疾病的诱发因素相同,而且一些心血管疾病治疗药物的不良反应就是ED。对于合并心血管疾病的ED患者,西地那非是否像普通人群中所证实的一样有效而安全呢?Olsson AM等人在一项研究中评价了西地那非治疗合并心血管疾病的ED患者的疗效和安全性[Int J Clin Pract,2001,55(3):171-176]。他们让正在服用β受体阻滞剂、血管紧张素转换酶抑制剂、钙离子拮抗剂或联合用药而未用硝酸甘油治疗的ED患者接受口服西地那非治疗。结果显示,患者接受西地那非治疗后,国际勃起功能问卷中评…     

西地那非的心血管安全性

男性心血管疾病患者中勃起功能障碍（ED）的发生率较高，对于此类人群ED的治疗既要有效又要保证安全性。TranD等人在题为“西地那非的心血管安全性”文章中对此问题进行了相关阐述。一些关于勃起功能障碍患者在服用西地那非（有时合并使用硝酸盐类药物）后发生心肌梗死和猝死事件的报道引起了人们对西地那非增加合并心血管疾病的ED患者心血管事件风险的担心。但一些有重要意义的数据显示了合并心血管疾病的ED患者使用西地那非总的来说是安全的。     

枸橼酸西地那非治疗合并心血管疾病ED患者有效且安全

Sildenafil: A 4-year update in the treatment of 20 million erectile dysfunction patients

Sildenafil citrate, the first internationally approved and widely used oral agent for the treatment of erectile dysfunction (ED), has revolutionized the treatment of ED throughout the past 5 years. This phosphodiesterase type-5 (PDE-5) inhibitor is selective for corpus cavernosum smooth muscle tissue and produces excellent erectile function. Its efficacy and safety over a wide variety of etiologies of ED and severities of ED demonstrates its usefulness in the clinical treatment of these patients. More than 20 million men have been treated worldwide with sildenafil with excellent results. ED caused by difficult-to-treat etiologies such as radical prostatectomy, severe diabetes, and spinal cord injury have demonstrated efficacy. Although sildenafil citrate, like all PDE-5 inhibitors, is contraindicated in patients taking nitrate medications for cardiac disease, it is effective and safe for those cardiovascular patients who are not taking nitrate medications. The incidence of adverse cardiovascular events in patients taking sildenafil does not differ from those of the general population. Investigations into the pharmacologic effect of sildenafil on coronary myocardial tissue further supports the safety of this medication. Sildenafil has been safe and effective in patients taking various medications including multiple antihypertensive drugs, selective serotonin reuptake inhibitors, cardiac, and diabetic medications.

Efficacy of oral sildenafil in hemodialysis patients with erectile dysfunction

The aim of this study was to evaluate the efficacy and safety of oral sildenafil to treat erectile dysfunction (ED) in chronic renal failure in patients on hemodialysis (HD). A double-blind, randomized, placebo-controlled study of oral sildenafil (50 mg) administered as required in HD patients with ED was designed. Patients on HD for at least 6 mo and who had a stable relationship with a female sexual partner were included. Patients older than 70 yr with penile anatomic abnormalities, cirrhosis, diabetes, angina, severe anemia, and those who were on nitrate treatment or with a recent history of stroke or myocardial infarction were not included. The International Index of Erectile Dysfunction (IIEF) was employed to evaluate ED and treatment response. Forty-one patients were evaluated (21 received placebo, and 20 sildenafil). Baseline clinical and demographic parameters were similar in both groups. Sildenafil was associated with improvement in the score of all questions and domains of the IIEF, except those related to sexual desire. Using the erectile function domain to evaluate primary efficacy, improvement was observed in 85% of the sildenafil patients compared with 9.5% of placebo patients. Sildenafil use resulted in normal EF scores in 35% of sildenafil patients. Sildenafil was well tolerated. Headaches and flushing occurred in both groups. Dyspepsia was reported by two patients in the sildenafil group. In conclusion, oral sildenafil seems to be an effective and safe treatment for ED in selected patients with chronic renal failure on hemodialysis.     

维持性血液透析患者勃起功能障碍的初步研究

目的 明确维持性血液透析（MHD）男性患者勃起障碍的发病率，及评价西地那非的疗效与副作用。方法 以国际勃起功能指数（IIEF）对22例HD男患者进行评分。勃起障碍者给予西地那非，每次从25mg/d开始，最高为100mg/d，治疗12周，对比治疗前后IIEF分值变化。结果 MHD勃起障碍发病率为72.73%。西地那非总有效率为87.5%。常见的副作用为头痛，面色潮红等。结论 西地那非对于正在接近血液透析治疗的肾衰患者安全性和有效性等同于其它人群。     

Sildenafil orodispersible film in the treatment of erectile dysfunction after radical prostatectomy: A single-centre open-label uncontrolled trial

Phosphodiesterase-5 inhibitors are the first-line therapy for erectile dysfunction (ED) after radical prostatectomy (RP). This single-centre open-label uncontrolled study evaluated the efficacy and safety of the new sildenafil orodispersible film (ODF) in ED treatment after RP. Sildenafil 100 mg ODF was administered twice a week for 3 months to patients under 75 years of age, with a Framingham cardiovascular risk score < 20% and a pre-operative International Index of Erectile Function (IIEF)-5 score ≥ 17, who had undergone open RP between 2016 and 2018. Erectile function was assessed pre-operatively, post-operatively and after treatment through the IIEF-5 score, the Sexual Encounter Profile Question (SEP-Q) 2 and SEP-Q3; adverse events (AE) were also investigated after 3 months. A total of 65 patients with a median (25th-75th percentile) post-operative IIEF-5 score of 8 (7–9) were treated. Nine (13.8%) patients reported AE of mild/moderate grade and discontinued treatment. A significant IIEF-5 score median (25th-75th percentile) increase of 10 (0–12) was found after treatment in the other 56 patients (p < .001). Sildenafil 100 mg ODF was effective in ED after RP in terms of improved IIEF-5 score and improved SEP-Q2 and SEP-Q3 in 67.9% of patients. It could represent a valid alternative for those patients with low compliance to tablet intake.     

Oral sildenafil (Viagra™) in male erectile dysfunction: use, efficacy and safety profile in an unselected cohort presenting to a British district general hospital.

Introduction

Sildenafil (Viagra^®) is one of the drugs used in the first line therapy of male erectile dysfunction (MED). We have recorded outcomes, adverse events and acceptability of Sildenafil (Viagra) therapy in an unselected group of men presenting with ED to a British district general hospital.

Methods

In this prospective observational study, 147 men with ED were seen since Oct 1999. Study patients were reviewed at 4, 12 and 52 weeks. All the patients filled the International Index of Erectile Function (IIEF) questionnaire and were asked about their willingness to pay (WTP) for treatment.

Results

All suitable men accepted Viagra as first line therapy. 91% of our patients found sildenafil treatment successful. 80% of these patients were willing to continue with sildenafil therapy. Side effect profile of sildenafil was different in this study with much higher incidence of headache, dyspepsia, flushing and abnormal vision. 92% of men with ED expect to be treated by the NHS. Of those men eligible for treatment in the NHS, 30% qualify under the clinical categories and 18% under the 'distress' category. Only 55% of those with cardiovascular risk factors qualify for NHS treatment.

Conclusions

Sildenafil is widely accepted as first line therapy among British men with ED and has a success rate of 91%. Nearly half of men with ED qualify for NHS treatment. Nearly half of those with vascular risk factors do not qualify for NHS treatment. Most men with ED could possibly be managed in primary care.     

Efficacy and safety of oral sildenafil citrate (Viagra) in the treatment of male erectile dysfunction in Colombia,Ecuador, and Venezuela: a double-blind,multicenter, placebo-controlled study

The objective of this work was to assess the efficacy and safety of sildenafil in patients with erectile dysfunction (ED) from Colombia, Ecuador, and Venezuela. One hundred and fifty-eight outpatients with ED participated in a double-blind, flexible-dose, randomized-controlled trial. Efficacy measures included question 3 (achieving an erection) and question 4 (maintaining an erection) from the International Index of Erectile Function (IIEF), the five functional domains of the IIEF, a global efficacy question, and patient event log. Sildenafil increased patients' ability to achieve/maintain erections (P<0.01). Seventy-seven per cent of sildenafil- vs 46% of placebo-treated patients reported improved erections (P<0.001). Sixty-five percent and 35% of intercourse attempts were successful among sildenafil and placebo patients, respectively (P<0.05). Sildenafil patients showed significant improvements in three of the five IIEF functional domains (P<0.05). Adverse events were reported for 51% and 33% of sildenafil and placebo patients, respectively. It can be concluded that sildenafil is an effective, well-tolerated treatment for ED in patients from Latin America.
