简要总结
- To study the early onset of symptomatic relief afforded by FLOMAX® capsules, 0.4 mg daily as compared to HYTRIN® capsules, 5 mg (with titration) daily in patients with the signs and symptoms of benign prostatic hyperplasia (BPH)
- To evaluate patient's tolerability to the use of FLOMAX® capsules 0.4 mg daily in comparison to HYTRIN® capsules, 5 mg (with titration) daily for the treatment of the symptoms of benign prostatic hyperplasia

- •Patients who are able to give written informed consent before performing screening examinations or tests
- •Patients being judged by the investigator to be reliable and able to follow protocol procedures (including the return visits schedule), and cooperate in the completion of tests related to safety and efficacy
排除标准
- •Patients with a history of an allergy to alpha blockers, alpha/beta blockers or patients who have had a "first dose hypotensive episode" upon starting therapy with an alpha blocker

- •Documented myocardial infarction (by ECG) within the past 6 months or evidence of a myocardial infarction on ECG whose age cannot be determined
- •New York Heart Association Class III or IV congestive heart failure
- •Prosthetic heart valves, cardiac devices or prior history of endocarditis
- •Clinically significant cardiac arrhythmias either diagnosed by ECG or recorded in the medical history, whether or not accompanied by symptoms (e.g., dizziness, presyncope, syncope, unsteadiness)

- •having taken < 80% or > 120% of prescribed doses during any visit interval between Visit (1, 2 or 3)
- •Postural symptoms during the initial placebo period, e.g., lightheadedness (on more than three occasions), fainting, blurring or loss of vision, profound weakness, or unsteadiness, with or without a change in blood pressure and/or pulse rate
