Brief Summary

Clinical effectiveness is of the finest tools to evaluate treatment success and is combined of 3 elements: treatment effectivity, side effect profile and patient compliance. Since the 3 main PDE5i's differ in their molecular structure, therapeutic profile and pharmacokinetics, it seems logical to assume that combining 2 different PDE5i's at lower dosage each may be beneficial in comparison to a single PDE5i maximal dose therapy. The aim of this study is to compare the clinical effectiveness of combination therapy (2 lower-dose PDE5i's) versus single maximal dose PDE5i therapy.
