Sure. That might be possible. To try this here are two options to consider:
(1) Gather up all his medical records and see which previous "drug cocktails" have already been tried over the years. Figure out a new mix to try. After all, you don't want to repeat the same ineffective treatment plans. And don't forget you might want to try a mix of both drugs and behavioral therapies, like ECT. You will want his full history to review. His parents probably can provide you with most of it.
(2) Without access to his entire medical history, do some research and come up with your own "strategically planned drug-assisted therapy" and offer it up to your girlfriend as a treatment option. She can convince her brother to give it a try.
Of course, given you have no experience your plan might actually backfire and cause more trauma. Have you considered that? Have you considered that while your intentions are good, that given you don't have any clue what you are doing, that whatever "help" you offer can actually add to the trauma? And maybe not just adding to the trauma for the brother, but for the parents and the girlfriend. Or do you think no matter what you offer up in the way of "cracking this nut" that it is impossible for you to be part of the problem rather than part of the solution?
After all, your very first "drug cocktail" might not work exactly as planned. It might take a few tries to get the mix of drugs just right. Not only will you not know the right mix, but you also will not know the frequency or correct dosages. For that you will need to seek out a licensed therapist. Will you use one of his former therapists or seek out a new therapist to help prescribe the treatment plan you develop?
(3) As a third option you might consider saying to yourself, "Hmm, the issues with her brother are definitely treatable, but it is nowhere in my scope of knowledge or abilities. I'm not yet a doctor, neuroscientist, therapist, pharmacist, hypnotist, or any other -ist that might be of any value in developing alternative treatments. Maybe I should be a "friend" in this situation as in boy-friend and use my time with my girlfriend to show my support for her struggles."
