Efficacy and safety of sildenafil citrate (Viagra) for the treatment of erectile dysfunction in men in Egypt and South Africa

The efficacy of sildenafil citrate (Viagra), an oral agent for the treatment of erectile dysfunction (ED), has been demonstrated in global studies. This 12-week randomized, double-blind, placebo-controlled, parallel-group, flexible-dose study assessed the efficacy and safety of sildenafil to treat ED in men in Egypt and South Africa. Men with ED of varied etiology were randomized to receive sildenafil 50 mg (n=128) or placebo (n=126); doses could be adjusted to 100 or 25 mg. Questions from the International Index of Erectile Function (IIEF) assessing the ability to achieve (Q3) and maintain (Q4) erections demonstrated a significant improvement with sildenafil compared with placebo (P<0.0001). Improved erections were reported by 74% of patients receiving sildenafil and 27% of those receiving placebo (P<0.0001). Headache, dyspepsia, and flushing were the most common adverse events in sildenafil-treated patients. These results are consistent with clinical trials in other countries. We conclude that sildenafil is an efficacious and well-tolerated treatment for men with ED in Egypt and South Africa.

Long-term efficacy and safety of oral Viagra (sildenafil citrate) in men with erectile dysfunction and the effect of randomised treatment withdrawal

The long-term efficacy and safety of oral Viagra (sildenafil citrate), a selective phosphodiesterase 5 inhibitor, and the effect of withdrawing treatment were evaluated in men with erectile dysfunction (ED). In 233 men with ED of psychogenic or mixed organic/psychogenic aetiology, 16 weeks of open-label, flexible-dose sildenafil treatment (10-100 mg) was followed by eight weeks of double-blind, fixed-dose, randomised withdrawal to placebo or continued treatment with sildenafil. Sildenafil was taken as needed (not more than once daily) approximately 1 h prior to sexual activity. The main outcome measures were a global efficacy question, a sexual function questionnaire, an event log of erections, and adverse event recording. In the open-label phase, 200 of 216 patients (93%) reported improved erections with sildenafil; 28 patients (12%) discontinued treatment. In the double-blind phase, the significant improvements in the frequency and duration of erections were maintained in the sildenafil group but returned to pre-treatment values in patients on placebo (P values < 0.0001 versus placebo). The most frequent adverse events in the sildenafil group during the double-blind phase were flushing (7%), headache (6%), and dyspepsia (5%). Of the 192 patients enrolled in the 1-y extension, 90% completed the study; only two patients (1%) were withdrawn due to lack of efficacy. In men with ED of psychogenic or mixed aetiology, oral sildenafil is effective and well-tolerated both at the initiation of therapy and during long-term treatment. For most patients, sildenafil treatment must be continued for improvements in erectile function to be maintained.     

Sildenafil: efficacy and safety in daily clinical experience

OBJECTIVES: Sildenafil citrate (Viagra) is a potent selective inhibitor of phosphodiesterase type 5 proposed for the oral treatment of erectile dysfunction (ED). The aim of this study was to evaluate its efficacy and safety when used in daily practice in patients with ED of various aetiology. PATIENTS AND METHODS: From September 1998 to April 1999, 380 patients chose sildenafil as treatment for their ED. One hundred and forty-five (38%) of them suffered from psychogenic ED, 125 (33%) organic and 110 (29%) of mixed aetiology. The grade of erection achieved and the occurrence of satisfactory sexual intercourse assessed the efficacy. Safety and tolerance were evaluated recording any side effect or adverse event. RESULTS: The overall efficacy of Viagra was 77%, with a response of 100% among the group of hormonal patients, 88% for psychogenic, 72% for mixed, 69% for diabetes, 65% for vascular and 60% for neurological symptoms. A few and mild to moderate side effects were recorded. CONCLUSION: These results indicate that the use of sildenafil citrate is an effective and well-tolerated therapy for men with ED of various aetiology with an overall success rate of 77%.

Sildenafil citrate (Viagra) in the treatment of men with erectile dysfunction in southern Latin America: a double-blind,randomized, placebo-controlled,parallel-group,multicenter, flexible-dose escalation study

Our objectives were: (1) to determine the efficacy, safety, and tolerability of sildenafil citrate (Viagra) administered to men with broad-spectrum erectile dysfunction (ED) in southern Latin America; and (2) to correlate Rigiscan measurements assessing ED etiology with the investigator's assessment. A total of 141 men with broad-spectrum ED (mean age 57) were enrolled in a randomized, 12-week, double-blind, placebo-controlled, flexible-dose escalation study of sildenafil. After the 12-week treatment period, the mean score for the primary efficacy variables had risen significantly: for the sildenafil group, 66.2% from baseline for question 3 of the International Index of Erectile Function and 77.6% for question 4, vs 15.1% and 21.2% for the placebo group, respectively (P<0.0001). Rigiscan data confirmed investigator assessments of etiology. Headache and flushing, usually mild and transient, were the most common adverse events. Sildenafil was an effective, well-tolerated treatment for men in southern Latin America with broad-spectrum ED.     

Assessment of the efficacy of Viagra (sildenafil citrate) using the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS)

Treatment satisfaction is a predictor of long-term compliance in patients with erectile dysfunction (ED). We assessed patient satisfaction with and efficacy of Viagra (sildenafil citrate) using the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) and 3 global efficacy questions. Twenty-nine men with ED who had completed a prior study of MUSE (alprostadil) versus Caverject (alprostadil) took a 50-mg dose of Viagra 1 h preceding intercourse. Efficacy and patient satisfaction with Viagra were high. Satisfaction as measured by EDITS was highly correlated to patients' final ED treatment choice. This correlation could make EDITS useful in identifying long-term patient satisfaction, and thus of considerable clinical benefit.
