Gut bacterial tyrosine decarboxylases restrict levels of levodopa in the treatment of Parkinson’s disease - Nature Communications

The gut microbiota can impact the bioavailability of therapeutic drugs. Here, the authors show that bacterial tyrosine decarboxylases (TDC) decrease the levels of levodopa, the primary treatment in Parkinson’s disease, by conversion to dopamine, and suggest TDC as a potential predictive biomarker for treatment.

Patients with Parkinson’s Disease are treated with levodopa, which is converted into the neurotransmitter dopamine in the brain. In a study that was published on 18 January in Nature Communications, we show that gut bacteria can metabolise levodopa into dopamine. As dopamine cannot cross the blood-brain barrier, this means the bacteria can compromise the availability of the medication, even in the presence of inhibitors that should prevent the conversion of levodopa.
