Naltrexone for alcohol/opioid addiction?

[equanimity]

Anyone here tried this, or know much about it?  My brother's counselor set him up with a psychiatrist for the sole purpose of getting him on this stuff to help treat the alcoholism.  It's an opioid receptor antagonist and I'm not sure how that factors in with alcoholism, but yeah.  Really hoping this helps somehow, but it still seems as though he's not taking it seriously.

I've heard of it helping the cravings for alcohol.

It would make opiate withdrawal quite a bit more painful, I'm not sure it's useful for that per say. Although people do use naltrexone in a Low Dose Naltrexone regiment where you take 1-3mg at night before bed and it upregulates opiate receptors for the next day as well as supposedly being helpful for a bunch of autoimmune conditions.
