                        I have spent two months in the hospital diagnosed with Collagenous Colitis, Sepsis, pneumonia.  I was given the drug Lotronex for an irritable bowel problem 3 months prior to my hospitalization.  I need to know what the difference is between Ischemic Colitis and Collagenous Colitis as I understand that Lotronex has been pulled from the market because of deaths and problems.
