Prescribing all phosphodiesterase 5 inhibitors to a patient with erectile dysfunction--a realistic and feasible option in everyday clinical practice--outcomes of a simple treatment regime
Abstract
OBJECTIVE: In clinical practice, to apply and evaluate outcomes of a treatment regime, in which the patient had the opportunity to try all the available phosphodiesterase 5 (PDE5) inhibitors.
METHODS: Patients eligible for treatment with PDE5 inhibitors were prescribed 8 tablets with a shorter-acting substance (four tablets sildenafil 100mg and four tablets vardenafil 20mg) and eight tablets with a long-acting substance (tadalafil 20mg). Outcomes of the regime were recorded.
RESULTS: Of the 186 patients, 64 (34%) had not been treated previously (naïve), and 122 (66%) were undergoing treatment for their erectile dysfunction. The overall treatment response was 89% (165 of 186 patients); 78% (n=145 of 186 patients) tested all three substances. No significant difference in choice between long- and shorter-acting medications in the overall material was observed. Two thirds of the naïve patients (n=64) preferred a shorter-acting substance (p<0.01). Every fifth man requested both a shorter- and a long-acting medication to accommodate his need.
CONCLUSION: If patients are given the opportunity in clinical practice to try all three available PDE5 inhibitors, the overall response rate is very high, almost 90%. No significant difference in patient preference between long- and shorter-acting drugs was observed. Treatment choice was based mainly on efficacy or duration of effect.
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: 186 participants or records.
