Study Notes
Metamucil (Psyllium) Overview
- Classification: Laxatives
- Indications: Used to manage simple or chronic constipation, particularly with low fiber diets. Benefits in reducing strain after procedures like MI or rectal surgery, and the treatment of chronic watery diarrhea.
- Mechanism of Action: Combines with water in intestinal contents, forming a gel that promotes peristalsis and reduces transit time.
- Therapeutic Effects: Provides relief and prevention of constipation.
- Absorption: Not absorbed from the gastrointestinal tract.
- Excretion: Eliminated through feces.
Administration and Dosage
- Adult oral dosage: 1-2 tsp./packet (3-6 g psyllium) mixed with a full glass of water, taken 2-3 times daily, up to 30 g daily in divided doses.
- Child oral dosage: For children over 6 years, 1 tsp./packet (1.5-3 g psyllium) in 4-8 oz of water, taken 2-3 times daily, up to 15 g daily in divided doses.
- Nursing Assessment: Monitor abdominal distention, bowel sounds, stool characteristics, and be aware of potential elevation in blood glucose levels with prolonged use of sugar-containing preparations.
Precautions and Side Effects
- Contraindications: Underlying hypersensitivity, abdominal pain with associated nausea/vomiting, severe adhesions, and dysphagia.
- Cautions: Some formulations may contain sugar or sodium; use with caution in patients with dietary restrictions.
- Adverse Reactions: Potential respiratory issues (like bronchospasm), gastrointestinal cramps, obstruction, nausea, or vomiting.
- Drug Interactions: Can decrease absorption of warfarin, salicylates, or digoxin.
Patient Education and Monitoring
- Encourage additional bowel regulation methods like diet enhancement with fiber, increased fluid consumption, and mobility.
- Instruct patients to avoid straining during bowel movements, especially those with cardiac conditions.
- Avoid use during episodes of abdominal pain, nausea, or fever.
Imodium (Loperamide) Overview
- Classification: Antidiarrheal
- Indications: Used as adjunctive therapy for acute diarrhea and chronic diarrhea associated with inflammatory bowel diseases. Decreases ileostomy drainage volume.
- Mechanism of Action: Inhibits peristalsis and prolongs transit time via direct action on intestinal nerve muscles; reduces fecal volume and increases bulk while minimizing fluid loss.
Administration and Pharmacokinetics
- Absorption: Poorly absorbed after oral administration.
- Protein Binding: Highly protein-bound at 97%.
- Metabolism: Processed by the liver with enterohepatic recirculation; approximately 30% is eliminated.
Therapeutic Effects
- Provides effective relief of diarrhea.
- Monitoring: Regular evaluation of stool consistency and frequency to assess treatment efficacy.
Awareness of Patient Condition
- Potential side effects and the importance of monitoring fluid and electrolyte balance, particularly during prolonged use, are critical in maintaining patient health.
