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

ABSTRACT

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.
