Clear Clinical Mechanism
Reduces intraprostatic and scalp DHT concentration by 70–90%, relieves BPH swelling and reverses hair follicle atrophy.
Mild Toxicity Profile
Low systemic adverse reactions; only rare mild sexual dysfunction reported, most symptoms resolve after sustained administration.
Excellent Oral Bioavailability
Average oral absorption rate reaches 63–65%, food does not interfere with absorption efficiency, plasma half-life 6–8 hours in adults, suitable for once-daily oral dosing scheme.
Benign Prostatic Hyperplasia (BPH) Medicine
Core raw material for oral tablets, used to shrink enlarged prostate, improve urinary flow and reduce acute urinary retention risk in male patients.
