Dutasteride, however, is a so-called dual inhibitor with both 5α-R1 and 5α-R2 inhibition. IC50 for 5α-R1 is 7 nM but 6 nM for 5α-R2. As mentioned above, it reduces DHT > 90% overall, or precisely % and for intraprostatic DHT the reduction is 97-99%. Dutasteride has also been found to inhibit 5α-R3, in vitro, with IC50= nM.  The 2,5-difluorophenyl side chain on the D-ring of the compound shows significant lipophilic features and as increased lipophilicity enhances the potency of the compounds binding at pocket site, its potency is much greater than of finasteride.
