The medications act differently on different people, and you would need to just use the trial and error approach, as everyone does; I do not believe that there are specific medications for anger and irritability, but all medications that act against manic tendencies might do the right thing for you.

I can share that the medication that gave me a distinctly tranquil, serene mood was Tegretol. Unfortunately, I developed a rash on it and had to come off. I wish I could tolerate Tegretol.
