Application

Finasteride has been used:
  • as a component of L-15 media to investigate the effects of finasteride exposure on brain, liver and testis tissues
  • in culture medium to treat tumor cells in vitro
  • as a positive control to treat benign prostatic hyperplasia (BPH)
  • to examine its effect on structural and molecular biology on the ventral prostate of senile mice

Biochem/physiol Actions

Finasteride can reduce serum and scalp dihydrotestosterone (DHT) by preventing the transformation of testosterone to DHT. It is usually used to manage benign prostate hyperplasia and pattern hair loss in male. Finasteride possesses androgen-distracting properties.
Selective 5α-reductase inhibitor; antiandrogen.
