Avodart (dutasteride) more potent. Avodart (dutasteride) effects can be seen fairly quickly, and it has always been the "new and improved" choice in the prostate enlargement size-reduction arena. Maintenance therapy on this medication can be effective enough to allow you to avoid a prostate roto-rooter surgery!
Bph. None really, but if diagnosed properly when symptoms first appear, 5-alpha reductase medications (finasteride or avodart) can result in significant shrinkage of the prostate and therefore to some degree halt or reverse the process causing symptoms. Avodart (dutasteride) has a much longer half life and may be a better choice if you tend to miss days of taking your meds.
