Clinical efficacy of daily low-dose tadalafil on erectile dysfunction-no sexual life
Abstract
Objective: Erectile dysfunction-no sexual life (ED-NS) is defined as the inability to have enough penile erection hardness and duration so as to have enough confidence in attempting sexual intercourse for more than six months. This study was to investigate the effect of daily low-dose tadalafil on ED-NS.
Methods: We treated 35 ED-NS patients aged 17-35 (25.9 +/- 3.9) years with oral tadalafil at 5 mg qd for 3 months and followed them up for another 3 months after drug withdrawal. We obtained the scores of the patients on Self-estimation Index of Erectile Function-No Sexual Life (SIEF-NS) and compared them before and after medication and at 3 months after drug withdrawal.
Results: The patients' SIEF-NS scores were 43.2 +/- 7.1 after medication and 42.1 +/- 7.4 at 3 months after drug withdrawal, both significantly higher than 21.2 +/- 5.9 before treatment (P 0.05).
Conclusion: Daily medication of low-dose tadalafil can significantly improve the erectile function of the patients with ED-NS.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, 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.
