What is the next best step for a patient with inadequate response to glycopyrrolate (anticholinergic medication) at a maximum dose of 1.8mg in 24 hours for secretions in palliative care, despite frequent suctioning?

Management of Inadequate Response to Glycopyrrolate for Secretions in Palliative Care

When a patient has inadequate response to glycopyrrolate at maximum dose (1.8mg/24hrs) for secretions in palliative care despite frequent suctioning, the next best step is to add scopolamine, either as 0.4mg subcutaneous injection every 4 hours as needed or as transdermal patches (1.5mg patches, 1-3 patches every 3 days). 1

Assessment of Current Management

• Glycopyrrolate is an anticholinergic medication used to reduce excessive secretions in palliative care at doses of 0.2-0.4mg every 2-6 hours, with a maximum daily dose of 1.8mg 1
• Glycopyrrolate has the advantage of not crossing the blood-brain barrier effectively, making it less likely to cause delirium compared to other anticholinergic agents 1
• Despite this advantage, glycopyrrolate can still produce anticholinergic side effects 1

Next Steps for Inadequate Response

First-Line Alternative: Add Scopolamine

• Add scopolamine 0.4mg subcutaneously every 4 hours as needed 1
• Alternatively, use transdermal scopolamine patches (1.5mg patches, 1-3 patches every 3 days) 1
• Important caveat: Transdermal scopolamine patches have an onset of benefit of about 12 hours, making them inappropriate for imminently dying patients 1
• For patients with imminent death, a subcutaneous injection of scopolamine can be administered when the patch is applied or if secretion management remains inadequate 1

Second-Line Alternatives

• Consider atropine 1% ophthalmic solution, 1-2 drops sublingually every 4 hours as needed 1
• Consider hyoscyamine 0.125mg PO/ODT/SL every 4 hours as needed (maximum: 1.5mg/day) 1

For Persistent Secretions Despite Above Interventions

• Consider octreotide 100-200 microgram subcutaneously every 8 hours 1
• For patients with diarrhea contributing to secretions, octreotide at doses of 100-500 mcg/day subcutaneously or IV, every 8 hours or by continuous infusion may be beneficial 1

Additional Considerations

• As life expectancy decreases in palliative care patients, the role of mechanical interventions diminishes while the importance of medications like opioids, benzodiazepines, glycopyrrolate, and scopolamine increases 1
• If fluid overload is contributing to secretions, consider:
  • Decreasing or discontinuing enteral or parenteral fluids 1
  • Adding low-dose diuretics 1
• For patients with anxiety associated with dyspnea and secretions, consider adding benzodiazepines (if benzodiazepine-naive, lorazepam 0.5-1mg PO every 4 hours as needed) 1

Special Considerations

• For patients in the last weeks to days of life (dying patients), intensify palliative care interventions and consider consultation with a palliative care specialist 1
• For intractable symptoms, sedation may be considered in consultation with palliative care specialists 1
• Ensure that all interventions remain consistent with the patient's goals of care 1

Remember that the management of secretions in palliative care requires ongoing reassessment and adjustment of the treatment plan based on the patient's response and changing needs as disease progresses.
