Levodopa is inactive by itself, but is the immediate precursor of transmitter dopamine. More than 95% of oral dose of Levodopa is decarboxylated in peripheral tissues and only 1-2% crosses brain. Levodopa is taken up by dopaminergic neurons and is converted to dopamine, which is stored and released as neurotransmitter. Carbidopa is an extracerebral dopa decarboxylase inhibitor. Carbidopa does not penetrate blood brain barrier and does not inhibit the conversion of levodopa to dopamine in brain.
