Generic Name:

Carbidopa and levodopa enteral

Duopa enteral suspension contains a combination of carbidopa and levodopa. Levodopa is converted to dopamine in the brain. Carbidopa helps prevent the breakdown of levodopa before it can reach the brain and take effect.

Duopa is used to treat movement problems in people with advanced Parkinson’s disease. Duopa reduces the “off time” effect associated with taking other medicines to treat Parkinson’s symptoms.

Duopa enteral suspension is a gel form of carbidopa and levodopa and is delivered at a constant rate throughout the day into the small intestine using an infusion pump via a surgically implanted tube. This delivery method avoids the stomach and improves the effectiveness of the medicine.
