Loperamide/simethicone Loperamide/simethicone Loperamide/simethicone is combination medication marketed under the trade name Imodium Multi-Symptom Relief (formerly Imodium A-D Advanced) used to treat diarrhea and gas simultaneously. It is manufactured by the McNeil Consumer Healthcare Division of McNeil PPC, Inc. Loperamide is a μ-opioid receptor agonist that works in the intestines. Although it is an opioid, it has no effects on the central nervous system. It reduces diarrhea by slowing the transit time of contents through the intestinal tract thereby allowing more water to be reabsorbed from the intestinal lumen. Simethicone reduces gas by allowing smaller gas bubbles to coalesce into larger bubbles
