Losartan
"I reviewed this drug 2 yrs ago after switching from Lisinopril because of intestinal angioedema. It reoccured for me with Losartan out if the blue after two years on this medicine. Did some digging and apparently it's fairly common if you've experienced it on Lisinopril to have it with losartan too. Bummer. It worked well for controlling my bp and helped me fall asleep quickly because I took it before bed. If you experience horrible abdominal pain on an ACE or ARB, could be intestinal angioedema. FYI"
