Lomotil Tablet contains a combination of Diphenoxylate (2.5 mg) and Atropine (0.025 mg), formulated for the management of acute and chronic diarrhea. Diphenoxylate is an opioid derivative that acts on the smooth muscle of the gastrointestinal tract to reduce motility, thereby increasing transit time and allowing for greater absorption of fluids and electrolytes. Atropine, an anticholinergic agent included in subtherapeutic doses, serves primarily to discourage abuse of the diphenoxylate component due to its unpleasant side effects at higher doses. Lomotil is indicated for symptomatic relief of diarrhea associated with various etiologies, including infectious and non-infectious causes. The medication should be used with caution in patients with underlying conditions such as obstructive jaundice, hepatic impairment, or a history of drug dependence. It is contraindicated in cases of diarrhea caused by enterotoxin-producing bacteria or pseudomembranous colitis. Common adverse effects may include dizziness, drowsiness, dry mouth, and mild abdominal discomfort. Lomotil should be administered according to prescribed dosages, and patients should be advised to maintain adequate hydration. Use during pregnancy and lactation requires careful consideration of risk versus benefit. This medication is intended for short-term use and should be discontinued if diarrhea persists beyond 48 hours or worsens.
