Abstract

OBJECTIVES:

To investigate the symptomatic and quality of life (QoL) response to treatment with tolterodine extended release (ER) in subgroups of male patients with Overactive Bladder Syndrome (OAB) and LUTS suggestive of non-obstructive benign prostatic hyperplasia (BPH) according to age, symptom severity, diabetes mellitus status, and concomitant treatment for LUTS.

METHODS:

Patients treated with tolterodine ER 4 mg/day for OAB symptoms, alone or added to unsuccessful alpha-blocker treatment of > or =6 weeks duration, and presumed non-obstructive BPH (Q (max) > or = 15 ml/s) were observed for 12 weeks in a non-interventional study. Patients completed the International Prostate Symptom Score (IPSS) and Overactive Bladder Questionnaire (OAB-q) at baseline and after 12 weeks.

RESULTS:

52.4% of 741 patients were aged < or =65 years; 4, 64, and 32% had mild, moderate, and severe symptoms, respectively, according to IPSS; 14% had diabetes mellitus, and in 42% tolterodine was added to alpha blockers. In the various subgroups, mean IPSS total scores improved by 2.8-11.1 points, IPSS QoL scores by 1.8-2.4 points, and all OAB-q subscores by more than 14 points. Only IPSS and OAB-q baseline scores had a relevant impact on changes during treatment, benefits were greatest in patients with more severe symptoms and bother.

CONCLUSIONS:

In men with symptoms of OAB and LUTS suggestive of non-obstructive BPH of all IPSS severity classes, aged < or =65 years or above, with or without concomitant diabetes or alpha-blockers, symptoms and QoL improved markedly during treatment with tolterodine ER.
