Long-Term Effectiveness and Safety of Dutasteride versus Finasteride in Patients with Male Androgenic Alopecia in South Korea: A Multicentre Chart Review Study

Background: Dutasteride improves hair growth compared with finasteride in male androgenic alopecia (AGA) and is well tolerated. However, real-world evidence for longterm dutasteride use in AGA is lacking. Objective: To describe baseline characteristics, treatment patterns and long-term safety and effectiveness of dutasteride versus finasteride. Methods: This was a multicentre, retrospective medical chart review study conducted in South Korea. The index date was the first prescription of dutasteride or finasteride. Baseline characteristics were assessed 6 months prior to index. Safety and effectiveness (improvements in basic and specific [BASP] classification) data were collected from index throughout the observation period. Results: Overall, 600 male adult patients were included (dutasteride, n=295; finasteride, n=305). Dutasteride-treated patients were older (p
