In the meta- analysis , tadalafil and sildenafil appeared to have similar efficacies and overall adverse event rates .
However , compared with sildenafil , tadalafil significantly improved psychological outcomes .
Furthermore , the patients and their partners preferred tadalafil over sildenafil , and no significant difference was found in the adherence and persistence rates between tadalafil and sildenafil .
Additionally , the myalgia and back pain rates were higher and the flushing rate was lower with tadalafil than with sildenafil .
Conclusion Tadalafil shares a similar efficacy and safety with sildenafil and significantly improves patients ’ sexual confidence .
Furthermore , patients and their partners prefer tadalafil to sildenafil .
Hence , tadalafil may be a better choice for ED treatment
Aims Erectile dysfunction ( ED ) is a major care problem worldwide .
Tadalafil and sildenafil are the two most common phosphodiesterase 5 inhibitors used to treat ED .
This systematic review and meta- analysis were conducted to directly compare tadalafil with sildenafil for the treatment of ED .
A randomized clinical trial investigating treatment choice in Chinese men receiving sildenafil citrate and tadalafil for treating erectile dysfunction
Sildenafil and tadalafil are efficacious and well tolerated in Chinese men with erectile dysfunction ( ED ) . Recent study results indicate that men with ED in China who were naïve to phosphodiesterase inhibitor type 5 ( PDE5 ) therapy prefer tadalafil 20-mg ( on-dem and ) versus sildenafil 100-mg ( on-dem and ) . Differences in psychosocial outcomes may help to explain treatment preference in favor of tadalafil . This open-label , r and omized , crossover study compared psychosocial outcomes and drug attribute choices between tadalafil and sildenafil in Chinese men with ED naïve to PDE5 inhibitor therapy . Eligible patients were r and omized to sequential 20-mg tadalafil/100-mg sildenafil ( n = 190 ) or 100-mg sildenafil/20-mg tadalafil ( n = 193 ) for 8 weeks each and were asked which treatment they preferred to take for the 8-week extension phase . Psychosocial outcomes were assessed using the Psychological and Interpersonal Relationship Scale ( PAIRS ) , Drug Attributes Question naire ( DRAQ ) , and Sexual Life Quality Question naire ( SLQQ ) . When taking tadalafil versus sildenafil , men had a higher mean endpoint score on the PAIRS Spontaneity Domain  ( tadalafil = 2.86 vs sildenafil = 2.72 ; P < 0.001 ) , and a lower mean endpoint score on the Time Concerns Domain ( tadalafil = 2.41 vs sildenafil = 2.55 ; P < 0.001 ) . A numerical increase in the Sexual Self-Confidence Domain was observed when taking tadalafil versus sildenafil ( tadalafil = 2.76 vs sildenafil = 2.72 ; P = 0.102 ) . The most frequently chosen drug attributes explaining treatment preference were able to get an erection long after having drug , and ability to get an erection every time . SLQQ results were comparable between treatment groups . These psychosocial outcomes may explain why more Chinese men preferred tadalafil versus sildenafil for the treatment of ED in this clinical trial
