Disproportionality analysis identified 91 ischaemic colitis signals and the top 30 drugs mainly involved in the gastrointestinal and nervous systems. The top five drugs with the highest reported OR, proportional reporting ratio, information component and the empirical Bayesian geometric mean, were alosetron, tegaserod, osmoprep, naratriptan and kayexalate.
