Its active ingredients are diphenoxylate and atropine. Diphenoxylate is anti-diarrheal and atropine is anticholinergic. Diphenoxylate is chemically related to the narcotic drug meperidine. A subtherapeutic amount of atropine sulfate is present to discourage deliberate overdosage. Atropine has no anti-diarrheal properties, but will cause tachycardia when overused. The medication diphenoxylate works by slowing down the movement of the intestines.
The inactive ingredients of Lomotil (as a liquid - it comes in pill form as well) are cherry flavor, citric acid, ethyl alcohol 15%, FD&C Yellow No. 6, glycerin, sodium phosphate, sorbitol, and water.
Other trade names for the same therapeutic combination are Lofene, Logen, Lomanate and Lonox, among others. In other countries, Lomotil may have other names.
In the United States, Lomotil (Diphenoxylate HCl and atropine sulfate) is classified as a Schedule V controlled substance by federal law, and is available only for a medical purpose.
