Giving patients with erectile dysfunction the opportunity to try all three available phosphodiesterase type 5 inhibitors contributes to better long-term treatment compliance
Abstract
INTRODUCTION: There are three phosphodiesterase type 5 (PDE5) inhibitors marketed, sildenafil, Vardenafil, and tadalafil for oral treatment of erectile dysfunction (ED). Although the treatment is simple and mostly effective, around 50% has ceased to use the medication within 2 years. One recently described way to improve the compliance is to let the patient try all the three PDE5 inhibitors and to prescribe the drug(s) he and his partner desires.
AIM: To study long-term compliance among patients who were treated according to this "three-drug regime."
MAIN OUTCOME MEASURES: Compliance and reasons for discontinuation after >2 years.
METHODS: The men who, during 2003, were enrolled in a treatment regime, where they had the opportunity to test all the three drugs and to chose the one(s) they preferred, were interviewed in 2006 by telephone concerning their ongoing ED treatment and the reason for discontinuation.
RESULTS: Of the 138 men, mean age 60 years (36-79 years), who had been enrolled and successfully treated with the three-drug regime, 127 (92%) could be reached. The mean follow-up time was 27 months (23-34 months). Of the 127 men, as many as 109 (86%) were still using PDE5 inhibitors. A few (8%) used more than two tablets per week. The majority (44%) used one to two tablets per week or one to two per month (43%), the others (5%) less often. The causes for discontinuation were varying. The most common reason (N = 7) was return of a satisfactory non-assisted erection.…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 138 participants or records.
