Study Notes
- Drugs affecting GI motility influence bowel movement and intestinal function.
Chemical Stimulant (Senna)
- Directly stimulates the nerve plexus in the intestinal wall.
- Increases bowel movement as a result.
- Indicated for constipation.
- Use with caution in patients with acute abdominal disorders, heart block, or CAD.
- Stimulating a bowel movement can overstimulate the vagus nerve, which is dangerous for these patients.
- Adverse effects include diarrhea, abdominal cramps, perianal irritation, and dependence on the medication.
- Encourage patients to drink lots of water to avoid constipation.
Osmotic Laxative (Magnesium Citrate)
- Increases motility in the GI tract.
- Increases fluid in the intestinal contents.
- Indicated for constipation, diagnostic procedures, and poisoning.
- Will pull everything out in 1-2 hours.
- Drug-to-drug interaction with beta blockers can cause hypoglycemia.
- Cautions and contraindications include acute abdominal disorders, fecal impaction, intestinal obstruction, and abdominal surgery.
- Adverse effects include severe abdominal cramps, perianal irritation, and diarrhea.
- Increase fluid intake and fiber in diet.
Antidiarrheal (Loperamide)
- Not for C. diff.
- Inhibits intestinal peristalsis.
- Slows motility and movement of water and electrolytes.
- Indicated for acute diarrhea and ileostomies, as ileostomies can cause liquid stool and irritation.
- Cautions and contraindications include diarrhea due to poisonings (C. diff).
- Do not administer with anticholinergics, as it can dry everything up.
- Use carefully in older patients.
