What is Dutas

Dutas is prescribed to treat the symptoms of Benign Prostatic Hyperplasia (BPH) in men.

It functions by shrinking the size of an enlarged prostate in males. 

It helps alleviate BPH symptoms such as trouble initiating urine flow, a weak stream, and needing to urinate frequently or urgently. 

Additionally, it may decrease the need for surgery to treat BPH. 

This is an FDA-approved medicine prescribed only to people with known medical conditions. 

Dr. Reddy's Laboratories is a leading pharmaceutical company that manufactures Dutas 0.5 mg.

Uses of Dutas

It is prescribed for treating Benign Prostatic Hyperplasia (BPH) in men.

Benign Prostatic Hyperplasia (BPH) 

As men age, Benign Prostatic Hyperplasia (BPH), often known as Prostate Gland Enlargement, is a common condition.

As the prostate gland enlarges, some muscles in the gland obstruct the tube that drains urine from the bladder.

This leads to uncomfortable urinary symptoms, such as the obstruction of urine flow from the bladder, increased frequency of urinating at night, etc. 

It can also cause bladder, urinary tract, and kidney difficulties.

How Dutas works

Dutasteride is an active ingredient of Dutas 0.5 mg, which is a 5-Alpha-Reductase (5-AR) inhibitor.

It blocks the activity of the enzyme 5-alpha-reductase, the enzyme responsible for converting testosterone to dihydrotestosterone. 

An excess of Dihydrotestosterone is responsible for Benign Prostatic Hyperplasia.

Inhibition of 5-AR leads to increased testosterone levels and decreased dihydrotestosterone levels.

It causes a reduction in prostate size, resulting in improved urinary flow.
