Abstract:
PURPOSE: Doxazosin has gained wide acceptance as a pharmacotherapeutic agents for the treatment of BPH. As a selective alpha-1 blocker, it is known to reduce symptom scores and improve flow rates. However, the correlation not been fully established. in this study we investigated that improvements of clinical parameters, such as the symptom score, storage symptom score, voiding symptom score, bother score, peak flow, post-voiding residuals and prostate volume, are statistically related to the subjective satisfaction in patients receiving doxazosin pharmacotherapy for the management of BPH. MATERIALS AND METHODS: Forty nine symptomatic BPH patients were evaluated prior to and at 3 months after the administration of recommended dose of doxazosin. The parameters evaluated were total symptom, storage symptom, voiding symptom and bother scores, peak flow rate (Qmax), post-voiding residuals (PVR) and prostate volume. The patients satisfaction to the treatment was determined by subjective responses to the questionnaires, and each response was categorized into one of the two groups; good (much improved, improved) or poor (slightly improved, no changes or getting worse). The subjective responses and the clinical parameters were compared and statistically analyzed. RESULTS: The total symptom, storage symptom, voiding symptom and bother scores decreased, and the Qmax increased significantly in all patients after doxazosin therapy. There was also significant mean posttherapeutic improvement for all individual questions. However, according to the patients subjective satisfaction for the treatment, patients with good result (23 patients) score then those with poor result group (26 patients; p<0.01). The changes of storage symptom score, Qmax, PVR and prostate volume were not significantly different in both groups. CONCLUSIONS: Doxazosin was effective in reducing symptoms and improving peak flow rates in the patients diagnosed clinically with BPH. Although the clinical parameters show significant improvements after doxazosin therapy, the patient satisfaction is more dependent on the severity of pre-treatment total and voiding symptom score. These findings suggest that pre-selecting patients prior to the initiation of doxazosin therapy could result in better treatment responses.
