Izonsteride
Izonsteride (LY-320,236) is a selective inhibitor of the 5α-reductase, with dual effects on both the type I and type II isoforms of the enzyme. It was under development by Eli Lilly and Company and Fujisawa for the treatment of benign prostatic hyperplasia but was never marketed. Izonsteride may also be useful in the treatment of androgenic alopecia.
