Effect of atorvastatin on erectile functions in comparison with regular tadalafil use. A prospective single-blind study
Abstract
OBJECTIVES: Erectile dysfunction (ED) is a common problem for elderly males. Higher serum lipid levels have important role in the pathogenesis, and in this prospective randomized trial, it is aimed to identify the effect of atorvastatin on erectile functions in comparison with regular tadalafil use.
MATERIALS AND METHODS: 120 patients with a minimum 3-months history of moderate-to-severe ED were involved. The patients were randomized to receive atorvastatin 10 mg/day, tadalafil 20 mg 3 times/week or no medication. Baseline serum testosterone, lipid levels IEEF and NPT test were performed and repeated after 3 months of treatment, and the 3 groups were compared.
RESULTS: Mean age of the whole population was 56 years (31-70). The 3 groups were well balanced for the baseline characteristics. Mean improvement of IIEF score was significantly higher in tadalafil group compared to atorvastatin (P = 0.01) and control group (P = 0.0001). Also atorvastatin showed significantly better improvement compared to control group (P = 0.001). Positive NPT test results in tadalafil group was significantly higher than atorvastatin group (25/40 (62.5%) vs. 16/41 (39%), P = 0.003) and compared to control group (25/40 (62.5%) vs. 3/39 (7.6%), P = 0.0001). At the same time, the difference between group 1 and group 3 was statistically significant (P = 0.001).
CONCLUSION: Tadalafil 20 mg three times/week shows better results than 10 mg atorvastatin daily. Atorvastatin alone seems to improve EF compared…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 120 participants or records.
