Cortisone, hydrocortisone, prednisone, Prednisolone, and budesonide are all corticosteroids and have similar immune suppressive and anti-inflammatory affect on the body.
Cortisone is metabolized into hydrocortisone within the liver. Hydrocortisone is a much weaker and shorter lived steroid than Prednisone which is both stronger and longer lasting.
Cortisone injections have their purpose but aren't used in IBD.
I cannot say much about collagen.
