Mechanism of Action

BENSERAZIDE
Levodopa is a precursor to the neurotransmitter dopamine which is administered to increase its levels in the central nervous system. However, most levodopa is decarboxylated to dopamine before it reaches the brain, and since dopamine is unable to cross the blood?brain barrier, this translates to little therapeutic gain with strong peripheral side effects. Benserazide inhibits the aforementioned decarboxylation, and since it itself cannot cross the blood?brain barrier, this allows dopamine to build up solely in the brain instead
CARBIDOPA
When mixed with levodopa, carbidopa inhibits the peripheral conversion of levodopa to dopamine and the decarboxylation of oxitriptan to serotonin by aromatic l-amino acid decarboxylase. This results in increased amount of levodopa and oxitriptan available for transport to the cns. Carbidopa also inhibits the metabolism of levodopa in the gi tract, thus, increasing the bioavailability of levodopa
