Dutasteride 0.5 mg


Dutasteride 0.5 mg sold under the name Dutaheal is an oral tablet used for the treatment of benign prostatic hyperplasia (BPH, also known as enlarged prostate) and hair loss (androgenetic alopecia) in men. It is either used alone or in combination with tamsulosin for the treatment of enlarged prostate. It improves urination difficulty by shrinking the size of the prostate. It also decreases the chances of having prostate gland surgery. It belongs to the class of drugs known as 5-alpha reductase inhibitors that help prevent the conversion of testosterone to dihydrotestosterone (DHT). It is meant to be taken with the help of a doctor’s prescription, usually once a day with or without food. It can take anywhere around 3 to 6 months to experience the complete benefits of this medicine.

How Dutasteride 0.5 mg Works

Dutasteride 0.5 mg belongs to the class of drugs known as 5-alpha reductase inhibitors. It is a dual inhibitor of both Type 1 and Type 2 5-alpha reductase that helps to prevent the conversion of testosterone to dihydrotestosterone (DHT). As compared to Finasteride which leads to only 70% serum DHT suppression, Dutasteride leads to 90% serum DHT suppression. The Type 2 5-alpha reductase is the predominant isoform in the normal prostate. On the other hand, the Type 1 form is known to predominate in prostate cancer cell lines. The suppression of serum DHT levels at a greater rate leads to a decrease in the size of the prostate, thereby leading to improved urinary flow. Also, by preventing the conversion of testosterone to DHT (which is a key contributor of androgenetic alopecia), the rate of hair loss is significantly reduced.
