Baclofen Administration and Efficacy

Introduction to Baclofen Therapy

• The American Geriatrics Society recommends starting with a low dose and gradually increasing the prescribed amount of baclofen to minimize common side effects, including dizziness, somnolence, and gastrointestinal discomfort 1
• Baclofen is a GABA-B receptor agonist used for various conditions, including spasticity, muscle spasm, gastroesophageal reflux disease (GERD), and alcohol use disorder, as stated by the Clinical Gastroenterology and Hepatology society 2, 3, 4

Clinical Applications and Considerations

• The Clinical Gastroenterology and Hepatology society suggests that baclofen can be effective for regurgitation or belch-predominant symptoms in GERD management, though it may cause central nervous system and GI side effects 2, 7
• The American Diabetes Association recommends taking medications like metformin with food or 15 minutes after a meal if gastrointestinal symptoms persist, a similar approach can be applied to baclofen administration 5, 6

Special Populations and Dosing

• The Clinical and Molecular Hepatology society states that baclofen has been used safely in patients with alcoholic liver cirrhosis to reduce alcohol craving and has shown improvement in liver function markers 3
• The Hepatology society advises that a 12-week course of baclofen (10 mg three times daily) improved abstinence rates with an acceptable safety profile in patients with both compensated and decompensated alcoholic cirrhosis 4
• The Hepatology society also recommends caution in patients with hepatic encephalopathy as baclofen may impair mentation, a side effect that could be exacerbated in advanced liver disease 4
