Drugs for BPH
Three medications with proven efficacy as monotherapy for treating BPH and lower urinary symptoms are:
- Tamsulosin (an alpha-adrenergic blocker)
- Finasteride (a 5-a-reductase inhibitor (if there is evidence of prostatic enlargement or a PSA level >1.5 ng/mL)
- Phosphodiesterase-5 inhibitor,
Antimuscarinics are sometimes used but do not have proven efficacy as monotherapy.
“Tamsulosin selectively antagonizes prostate alpha-1a adrenergic receptors, relaxing smooth muscles and improving urine flow (peripherally-acting alpha blocker)” Epocrates
