Rectal Administration of Carbidopa/Levodopa

Area of Science:

• Neurology
• Pharmacology

Background:

• Parkinson disease management relies heavily on carbidopa/levodopa.
• Oral administration challenges arise in certain clinical scenarios, necessitating alternative delivery methods.

Observation:

• A 90-year-old male with Parkinson disease experienced confusion and agitation.
• Enteric access was not obtainable for this patient.

Findings:

• Rectal administration of carbidopa/levodopa was performed.
• A notable reduction in Parkinson disease symptoms was observed following rectal administration.

Implications:

• Rectal carbidopa/levodopa presents a viable alternative route for Parkinson disease patients.
• This method can be effective in preventing complications when oral medication is not possible.
