Gastrointestinal (GI) medications are among the most frequently prescribed drug classes in long-term care (LTC) facilities, heavily utilized to manage age-related physiological changes, chronic conditions, and drug-induced GI complications. Because frail older adults metabolize drugs differently, facility clinical teams must carefully balance the therapeutic benefits of these medications against risks like polypharmacy, infections, and cognitive decline. Essential GI Medication Classes in LTC
Clinical management protocols in long-term care settings typically rely on five major functional classes of gastrointestinal medications: 1. Laxatives and Cathartics
These represent the most highly utilized GI medications in nursing homes due to widespread immobility, low fluid intake, and opioid-induced bowel dysfunction.
Osmotic Laxatives: Polyethylene glycol 3350 (Miralax) and Magnesium hydroxide (Milk of Magnesia). These are highly effective and generally well-tolerated first-line choices for older adults.
Bulk-Forming Laxatives: Psyllium (Metamucil), which safely adds bulk to stool but requires adequate resident hydration to prevent impaction.
Lubricants and Softeners: Docusate sodium (Colace), though frequently prescribed, has shown limited clinical efficacy in standalone trials.
Chloride Channel Activators: Lubiprostone (Amitiza) is increasingly utilized for severe, chronic treatment-resistant constipation or recurrent fecal impaction. 2. Acid Reducers (Anti-Ulcer Agents)
Prescribed heavily to treat Gastroesophageal Reflux Disease (GERD) and prevent gastric ulcers caused by the chronic use of NSAIDs or steroids. Medicines and the Digestive System
