Schizophrenia. To get him out of this.

Hello, my elder brother was diagnosed with schizophrenia 5 years back. In these 5 years he was on and off the treatment. Whenever he withdraws himself from the treatment, he goes through a psychotic episode. As he is aging up, it's getting worse. Recently, previous month, he was having a upset stomach due to the medicines that is what he told us and stopped the medications. He strongly denies to take medicines. My mother is the only person who takes care of him. I live out of the town. Mom tried to give him medicines through food, however he sensed it and stopped eating anything at home. He is doubting Mom and blaming her even for small issues. No doubt, he is having a psychotic episode but we are helpless, as he denies to take medicines and visit the doctor. He gets violent if we forcefully give him the medicines. It's very hard to see my brother like this and worst is not being able to help him. Could you please suggest any other way to give him medicines to get him out of this.
