Duprost capsules  are used to treat benign prostatic hyperplasia (BPH), which is an enlarged prostate gland.  Duprost capsules  help to shrink the prostate and reduce the risk of urinary retention caused by restricted urine flow as the prostate gland becomes enlarged and presses against the urethra (urine outlet tube from the bladder), which helps urine to flow more easily, prevents urine backlog in the bladder and restores bladder control. This relieves symptoms like need for frequent urination, inability to empty the bladder, strain and difficulty passing urine. The improved urine flow and reduction in symptoms may reduce the need for surgery due to moderate to severe symptoms of BHP. As a side effect of its intended use, Duprost capsules 0.5mg are also used to treat male pattern hair loss (androgenetic alopecia) by increasing hair growth and preventing further hair loss from all areas of the scalp, including the front.  This can reverse balding in men with mild to moderate hair loss but does not restore hair that has been lost for a long time.  Duprost capsules 0.5mg are not used to treat hair loss in women.
