Antidiarrheal agents primarily reduce diarrhea through decreasing intestinal motility. This mechanism allows the intestines more time to absorb water and electrolytes from the contents passing through, leading to stool that is firmer and less frequent. By slowing down the movement of the intestines, these agents help to regulate the bowel's activity and mitigate the symptoms of diarrhea.

Understanding the role of intestinal motility is crucial, as increased motility typically leads to quicker transit times and less absorption, worsening diarrhea. Thus, by targeting and reducing motility, antidiarrheal medications effectively help to manage the condition and alleviate symptoms.
