Gut bacteria could be responsible for side effect of Parkinson's drug

Bacteria in the small intestine can deaminate levodopa, the main drug that is used to treat Parkinson's disease.

Since the disease is already associated with constipation, processing of the drug by gut bacteria may worsen gastrointestinal complications.
