title: [Low-dose tadalafil combined with Shuganyiyang capsules for mild-to-moderate erectile dysfunction].
abstract: OBJECTIVE
  To observe the clinical effect of low-dose once-daily tadalafil combined with Shuganyiyang Capsules in the treatment of mild-to-moderate erectile dysfunction (ED).
  
  
  METHODS
  Ninety patients with mild-to-moderate ED were equally randomized to groups A, B and C to receive Shuganyiyang Capsules, tadalafil, and tadalafil + Shuganyiyang Capsules, respectively. The scores of the patients on IIEF-5 and SF-PAIRS (15-Item Short Form of Psychological Interpersonal Relationship Scales) were recorded before and at 1 and 3 months after treatment.
  
  
  RESULTS
  The IIEF-5 scores of groups A, B and C were 10.13 +/- 1.55, 11.00 + 1.60 and 10.73 +/- 1.91 before treatment, and 13.77 +/- 2.11, 17.77 +/- 2.13 and 17.17 +/- 3.84 at 1 month after treatment, significantly higher in B and C than in A (P <0. 001) , but with no remarkable difference between B and C (P =0. 411). At 3 months after treatment, the IIEF-5 scores were 15.77 +/- 2.05, 18.07 +/- 2.24 and 19.37 +/- 3.76 in the three groups, dramatically higher in B and C than in A (P <0.001) as well as in C than in B (P<0.05). The scores on sexual self-confidence, sexual spontaneity and time concerns in SF-PAIRS were 3.90 +/-0.80, 8.67 +/- 1.94 and 14.43 +/- 1.92 before medication, 5.83 +/- 1.02, 9.90 +/- 1.75 and 11.17 +/- 1.68 at 1 month and 6.73 +/- 0.98, 11.07 +/- 2.08 and 10.67 +/-1.60 at 3 months after medication in group A; 4.17 +/- 0.87, 9.37 +/-1.43 and 14.47 +/-1.57 before medication, 6.47 +/-0.78, 10.83 +/- 2.18 and 10.20 +/-1.56 at 1 month and 6.83 +/-0.91, 11.30 +/- 1.88 and 9.47 +/- 1.57 at 3 months in group B; and 4.23 +/-0. 94, 9.50 +/- 1.89 and 14.67 +/- 2.91 before medication, 8.03 +/- 1.67, 13.43 +/-1.10 and 9.70 +/-1.21 at 1 month and 8.93 +/- 1.78, 14.70 +/- 1.26 and 8. 87 +/- 0. 97 at 3 months in group C. Compared with the baseline, the SF-PAIRS scores of the three groups were all significantly improved after treatment (P <0. 05) , and markedly higher in C than in the other two groups (P <0.05).
  
  
  CONCLUSIONS
  Low-dose once-daily tadalafil combined with Shuganyiyang Capsules is obviously effective in the treatment of mild-to-moderate ED, which not only improves the patients'erectile function, sexual self-confidence and sexual spontaneity, but also reduces their time concerns.
