Finasteride has, since its original introduction,
been reported to be less effective in treating BPH than
originally eXpected (R. S. Rittmaster, N. Engl. J. Med., 1994,
330, 120-125). According to reports, there is room for
further improvement in the level of residual circulating DHT
(20-40%) in patients undergoing treatment With ?nasteride
(G. J. Gormley et. al., J. Clin. Endocrinol. Metab., 1990, 70,
1136-1141).
