Duopa Key Facts
What is Duopa?
Duopa is the brand name for carbidopa/levodopa and is available as enteral suspension.

What is Duopa used for?
Duopa is a combination medication that treats symptoms of advanced Parkinson’s disease (PD), particularly movement problems.
How does Duopa work?
Duopa is a combination medication used to increase dopamine levels in the brain. Levodopa is a dopamine replacement. Once you take levodopa, it travels into the brain where it turns into dopamine. Carbidopa is a dopa decarboxylase inhibitor. It stops dopa decarboxylase, a protein in the body that breaks down levodopa before levodopa can reach the brain. By blocking this protein, more levodopa can get to the brain and turn into dopamine. This increases levodopa’s ability to relieve PD symptoms.

Duopa is given using a pump that sends the medication into your intestine through a PEG-J tube. The infusion pump is set up for your specific treatment plan.
