  What are alpha blockers?

  Alpha blockers are able to relax certain muscles in the bladder and prostate. In doing so, they reduce pressure on the urethra, which in turn improves urine flow. Alpha blockers are not a cure for BPH. But, within six weeks, they can help to improve symptoms by 29-50% and flow rates by 20-30%.

  What are five alpha reductase inhibitors?

  Five-alpha-reductase inhibitors shrink the size of the prostate and, as a result, help to relieve urine obstruction. They do this by stopping the production of DHT, the enzyme needed for the prostate to grow. Five-alpha-reductase inhibitors can take up to six months to be effective.
