What is the primary use of Lomotil?

Lomotil is primarily used to relieve diarrhea. It is a medication that contains two active ingredients: diphenoxylate and atropine. Diphenoxylate works by slowing down the movement in the gut, which helps decrease the number of bowel movements and makes the stool less watery. Atropine is included to discourage abuse of the medication, as it can cause unpleasant side effects when taken in higher doses.

The focus of Lomotil as a treatment is specifically aimed at managing symptoms of diarrhea, whether it is acute or chronic. This makes it distinct from medications that treat nausea, provide pain relief as analgesics, or promote urination as diuretics. Each of those types of medications has different mechanisms and intended uses that do not overlap with the therapeutic goals of Lomotil. Thus, the correct answer reflects the specific action and intended purpose of Lomotil in managing diarrhea effectively.
