  • Combination therapy for the treatment of benign prostatic hyperplasia
    Patent number: 6410554
    Abstract: This invention relates to combination therapy for the treatment of benign prostatic hyperplasia comprising an alpha-1a antagonist and an endothelin antagonist. More specifically, the use of a selective alpha-1a adrenergic receptor antagonist in combination with a subtype non-selective endothelin antagonist provides relief of lower urinary tract symptoms in patients with symptomatic prostatism or benign prostatic hyperplasia. This combination therapy improves lower urinary tract symptoms including increasing urine flow rate, decreasing residual urine volume and improving overall obstructive and irritative symptoms in patients with benign prostatic hyperplasia or symptomatic prostatism.
