question: What is the benserazide's mechanism of function when co-administered with L-DOPA in patients with Parkinson's Disease?
answer: Benserazide is a peripheral decarboxylase inhibitor. Benserazide in combination with L-DOPA constitutes a slow-release formulation of L-DOPA in patients with Parkinson's disease (PD), it reduces peaks and rapid fluctuations of L-DOPA plasma levels (possibly responsible for peak-dose dyskinesias and end-of-dose deterioration) and considered as the best available therapy.
