BPH: costs and treatment outcomes.

Author information

Empire 4, Kingston, Ontario, Canada.


The current treatments for benign prostatic hyperplasia (BPH) include pharmacotherapy with alpha1-selective adrenergic receptor (a1-AR) antagonists, 5-alpha-reductase inhibitors (5-aRIs), and a range of invasive and minimally invasive interventions, each of which is effective in the amelioration of lower urinary tract symptoms (LUTS) and the prevention of symptom progression and BPH-related complications. Pharmacotherapy is considered the mainstay of treatment for LUTS caused by BPH. The available a1-AR antagonists have comparable efficacy for the relief of LUTS and to enhance patients' quality of life. The use of nonsubtype-selective drugs in this class may precipitate vasodilatory adverse events such as dizziness, somnolence, and orthostatic hypotension. Based on current studies, a1-AR antagonists are more cost effective (particularly the subtype-selective a1-AR antagonist, tamsulosin) than the 5-aRIs (eg, finasteride) and comparable in cost to transurethral resection of the prostate and minimally invasive therapies. There are few cost-effectiveness studies comparing the various pharmacologic interventions for BPH. Only 1 cost-analysis model has addressed the impact of adverse events on the cost effectiveness of pharmacotherapy for BPH. The publication of additional analyses would contribute to the appropriate selection of therapy in patients with BPH.
