Abstract:
OBJECTIVETo evaluate the effectiveness of the monotherapy of Cardura and the combination therapy of Cardura and Tolterodine L-Tartrate Tablets for II° ? benign prostate hyperplasia (BPH) with overactive bladder (OAB).
METHODSThis study included 87 cases of BPH with OAB, with a disease course > or = 3 months, daily urination > or = 8 times, nocturnal urination > or = 2 times, urine volume < 200 ml per time, International Prostate Symptom Score (IPSS) > or = 8, OAB symptom score (OABS) > or = 3, quality of life score (QOL) > or = 3, post-void residual (PVR) < or = 100 ml, maximum urinary flow (Qmax) > or = 5 ml/s, prostate weight 25-50 g, and PSA < 4 microg/L. We randomized the patients to a monotherapy group (n = 44) and combination group (n = 43), the former treated with Cardura 4 mg qd, and the latter with Cardura 4 mg + Tolterodine L-Tartrate Tablets 4 mg qd, both for 8 weeks. Then we recorded the IPSS, OABS, Qmax, PVR, PSA, and adverse events.
RESULTSThe baseline parameters showed no significant differences between the two groups (P > 0.05). In comparison with the baseline, both the monotherapy group and the combination therapy group showed significant decreased in the IPSS (16.50 +/- 4.27 vs 13.68 +/- 3.69 and 15.51 +/- 3.80 vs 11.49 +/- 2.75), urine storage symptom score (10.48 +/- 2.75 vs 7.98 +/- 2.34 and 9.47 +/- 2.31 vs 5.74 +/- 1.66), OABS (8.55 +/- 2.69 vs 6.32 +/- 1.97 and 8.21 +/- 2.55 vs 4.44 +/- 1.62), urgent micturition score (4.25 +/- 1.06 vs 3.23 +/- 0.99 and 4.07 +/- 0.83 vs 2.26 +/- 1.05), QOL (5.36 +/- 0.72 vs 3.43 +/- 0.66 and 5.07 +/- 0.86 vs 2.37 +/- 0.76) and PVR ([44.55 +/- 22.39] vs [38.30 +/- 20.20] ml and [36.19 +/- 21.21] vs [24.98 +/- 17.60] ml) (P < 0.01). All the six parameters were significantly more improved in the combination therapy group than in the monotherapy group (P < 0.01), but there were no remarkable differences between the groups in Qmax and voiding symptom score (P > 0.05). Neither group exhibited significant changes in the PSA level and prostate weight after treatment as compared with the baseline (P > 0.05). No acute urinary retention and other severe adverse reactions were observed during the medication.
CONCLUSIONBoth Cardura monotherapy and the combination therapy of Cardura + Tolterodine L-Tartrate Tablets can improve II ? BPH with OAB, and the latter has an even better efficacy than the former.
