For common outcomes there was similar efficacy between PDE-5 inhibitors
Background There are no r and omised and properly blinded trials directly comparing one PDE-5 inhibitor with another in a normal home setting .
Valid indirect comparisons with a common comparator must examine equivalent doses , similar duration , similar population s , with the same outcomes reported in the same way .
Sildenafil citrate (Viagra) in erectile dysfunction: near normalization in men with broad-spectrum erectile dysfunction compared with age-matched healthy control subjects.
OBJECTIVES To evaluate the efficacy , safety , and tolerability of sildenafil in men with broad-spectrum erectile dysfunction ( ED ) , with reference to age-matched healthy control subjects . METHODS One hundred eleven patients were enrolled in a r and omized , double-blind , placebo-controlled , parallel-group , 12-week , flexible-dose study . Efficacy assessment s included the International Index of Erectile Function ( IIEF ) , a global assessment question , and patient event log data . In a separate , nontreatment study , 109 control subjects also completed the IIEF . RESULTS Mean IIEF scores at baseline were significantly lower for patients with ED than for control subjects without a history of ED . After treatment , mean IIEF scores for patients receiving sildenafil approached values observed in control subjects and were significantly higher than mean scores for patients receiving placebo ( P<0.01 ) . Responses to the global assessment question and patient log data corroborated the IIEF results . Sildenafil was well tolerated , with no discontinuations because of adverse events . CONCLUSIONS The results indicate that sildenafil , an effective oral therapy for the treatment of broad-spectrum ED , is associated with a near normalization of patient erectile function
