title: Treatment satisfaction in patients with erectile dysfunction switching from prostaglandin E(1) intracavernosal injection therapy to oral sildenafil citrate.
abstract: Treatment satisfaction, subanalysed by demographic variables, was evaluated in patients switching from successful intracavernosal prostaglandin E(1) (PGE(1)) therapy to oral sildenafil citrate. The validated Erectile Dysfunction Inventory of Treatment Satisfaction questionnaire was administered at the end of PGE(1) therapy and after 12 weeks of sildenafil treatment in a multicentre, open-label study. Men with erectile dysfunction (n=176) who were switched from stable PGE(1) therapy to sildenafil (25-100 mg) were equally satisfied with onset of action, duration of action, and confidence in ability to engage in sexual activity, but expressed greater overall treatment satisfaction with sildenafil (P<0.01), better ease of use (P<0.001), naturalness of erectile process (P<0.001), and intention to continue treatment (P<0.001). Partners (n=32) were overall more satisfied with sildenafil (P<0.05), and their responses correlated with patient satisfaction (r=0.68). Compared with PGE(1) injection, these data suggest that patients may be less likely to discontinue taking sildenafil treatment for their erectile dysfunction.
