How much do you know about BPH?

1. When treating Benign Prostatic Hyperplasia (BPH) a reduction in prostate size and disease progression can be achieved by:

A: an alpha-blocker such as tamsulosin

B: a phosphodiesterase type 5 (PDE-5) inhibitor such as vardenafil, sildenafil or tadalafil

C: a 5-alpha reductase inhibitor (5-ARI) such as dutasteride

The answer is C. 5-alpha reductase (5-AR) converts testosterone into dihydrotestosterone (DHT), which stimulates prostate tissue proliferation.1 Inhibiting 5-AR with dutasteride reduces prostate size (resulting in improved urinary flow) and prevents progression of BPH in the longer term.1,
