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
Number needed to treat Number needed to treat The number needed to treat (NNT) is an epidemiological measure used in communicating the effectiveness of a health-care intervention, typically a treatment with medication. The NNT is the average number of patients who need to be treated to prevent one additional bad outcome (e.g. the number of patients that need to be treated for one of them to benefit compared with a control in a clinical trial). It is defined as the inverse of the absolute risk reduction, and computed as formula_1, where formula_2 is the incidence in the treated (exposed) group, and formula_3 is the
