placebo + dutasteride

This is a combination of a placebo (an inactive substance with no therapeutic effect) and dutasteride, a small molecule drug used primarily to treat benign prostatic hyperplasia (BPH), or enlargement of the prostate gland, in adult males. Dutasteride is a 5-alpha reductase inhibitor that blocks both type I and type II isoforms of the enzyme responsible for converting testosterone to dihydrotestosterone (DHT). By reducing DHT levels, dutasteride decreases prostate size and improves urinary symptoms associated with BPH. Placebo serves as an inert comparator in clinical trials or studies evaluating the efficacy and safety of dutasteride[1][3][4][5].
