You, by yourself can not
do anything without him wanting to
do it. You can haul his behind to an NA meeting, you can get him into rehab, you can even get him to my clinic and I will get him physically clean, but without his commitment and his desire to stay clean, all of it is useless. Suboxone is just another opiate, it does work for some, but again, a person needs to want to quit. Your brother does not.
