PurposeWe determined the clinical efficacy and safety of terazosin in the treatment of patients with female lower urinary tract symptoms.Materials and MethodsA total of 100 females 20 to 70 years old who met the inclusion criteria of total International Prostate Symptom Score 8 or greater, symptom duration 1 or more months, and did not meet any exclusion criteria were entered into the study. Subjects were randomized to receive terazosin or placebo in titrated dose from 1 mg od, 1 mg twice daily to 2 mg twice daily during 14 weeks. Successful treatment outcomes use primary end point of International Prostate Symptom Score quality of life 2 or less and secondary end point of total International Prostate Symptom Score 7 or less. Other outcome measures included International Prostate Symptom Score individual item scores, King’s Health Questionnaire quality of life domains, objective assessment parameters of 24-hour frequency volume chart, maximum flow rate and post-void residual urine.ResultsUsing a primary end point, 32 of 40 (80%) evaluable terazosin subjects responded in contrast to 22 of 40 (55%) evaluable placebo subjects (p <0.02). The secondary end point revealed a successful outcome in 85% of terazosin subjects vs 55% in placebo (p <0.01). Of the 7 International Prostate Symptom Score individual item scores, only item scores of frequency and straining showed statistically significant reductions with terazosin (p <0.01). All King’s Health Questionnaire quality of life domains except domain of severity measures showed statistically significant improvement with terazosin (p <0.05). There were no differences between treatment groups in all objective assessment parameters. Of all evaluable subjects 23 of 40 (58%) on placebo experienced adverse events vs 16 of 40 (40%) on terazosin (p >0.05).ConclusionsTerazosin proved to be more effective and safe than placebo in patients with female lower urinary tract symptoms.
