    TLDR Long-term finasteride use doesn't change bone density or metabolism.
    The study aimed to evaluate the effect of finasteride, a 5α-reductase inhibitor, on bone density and metabolism in elderly men. The results showed that prolonged treatment with finasteride did not affect bone density or mineral metabolism, except for a small increase in 1,25(OH)₂D3 serum concentration. The study suggests that finasteride is a safe drug as pertains to bone and mineral metabolism.
