Answer

Antidiarrheals

Adsorbents (eg, attapulgite, aluminum hydroxide) help patients have more control over the timing of defecation but do not alter the course of the disease or reduce fluid loss. Antisecretory agents (eg, bismuth subsalicylate) may be useful. Antiperistaltics (opiate derivatives) should not be used in patients with fever, systemic toxicity, bloody diarrhea, or in patients whose condition either shows no improvement or deteriorates.

Attapulgite (Kaopectate, Diasorb)

Adsorbent and protectant that controls diarrhea.

Aluminum hydroxide (Amphojel, Dialume, ALternaGEL)

Commonly used as an antacid. Adsorbent and protectant that controls diarrhea.

Bismuth subsalicylate (Pepto-Bismol)

Antisecretory agent that also may have antimicrobial and anti-inflammatory effects.

Diphenoxylate and atropine (Lomotil, Lonox)

Drug combination that consists of diphenoxylate, which is a constipating meperidine congener, and atropine to discourage abuse. Inhibits excessive GI propulsion and motility.

Available in tabs (2.5 mg diphenoxylate) and liquid (2.5 mg diphenoxylate/5 mL).

Loperamide (Imodium)

Acts on intestinal muscles to inhibit peristalsis and slow intestinal motility. Prolongs movement of electrolytes and fluid through bowel and increases viscosity and loss of fluids and electrolytes.

Available over the counter in 2-mg capsules and liquid (1 mg/5 mL).
