Dutasteride is a drug used in the treatment of benign prostatic hyperplasia. This refers to, in effect, the enlargement of the prostate gland. This condition can have damaging lifestyle consequences to those afflicted, as it not only disrupts urine output during the day, but also at night. One of the reasons for the enlargement is old age. A second reason, however, focuses on testosterone. Dutasteride functions to disrupt the conversion of testosterone to dihydrotestosterone. By disrupting this process, it prevents the further enlargement of the prostate gland. As a result, though, long-term severe side-effects can include erectile dysfunction and prostate cancer. Dutasteride also known as Avodart- a soft gelatin capsule. It is a reductase inhibitor which inhibits conversation of testosterone to that of dihydrotestosterone. It is used to manage a condition known us symptomatic benign prostatic hyperplasia in men with enlarged prostate. Also used to reduce the risk of urinary retention and need for related surgery. It reduces the size of the enlarged prostate hence reducing the risk of BPH surgery. Additionally, this drug lowers dihydrotestosterone (DHT) hormone that causes prostate growth. DHT causes the enlarged prostate gland to shrink when its levels get reduced. There is no sufficient data to support any risk of death with this drug.
