The mesalamine is the same medication as asacol, colazal, etc. It's just placed directly into the colon when you use the enema. I use these fairly regularly. The hydrocortisone is a steroid, so it is generally used when you need something more than mesalamine. I use these when flaring and the mesalamine enemas stop working. Definitely try the mesalamine first. Save the steroids for when absolutely needed.
