Avodart
® (
dutasteride) is a prescription medicine that has been licensed to treat an
enlarged prostate. An enlarged prostate is also known medically as benign prostatic hyperplasia, benign prostatic hypertrophy, or
BPH. It is approved to be used alone or in combination with
tamsulosin (
Flomax®), another BPH medication.
It is manufactured by GlaxoSmithKline.
Avodart works by blocking the conversion of testosterone into DHT (dihydrotestosterone), thereby decreasing the amount of DHT in the body. Since DHT is responsible for enlarging the prostate, using Avodart to decrease DHT levels can treat an enlarged prostate. In most men, the medication can help shrink the enlarged prostate, helping to relieve their
enlarged prostate symptoms.
There have been several studies looking at how well Avodart treats an enlarged prostate. These studies showed the following effects related to Avodart and men with BPH.
