Can anyone tell me about this drug? I'm just finding out that my deceased girlfriend s dad is supposed to be on this. He had 2/3 of his stomach removed and the vagus nerve clipped. I'm trying to help take care of him. ## Hello, Brenda! How are you? It's listed as containing the active ingredient Glutamic Acid Hydrochloride, from the information I've found from the NIH, it's used to help aid in digestion for those who have had such surgeries. I do not, however, have any information on its availability. Does anyone else know more?
