Why levodopa is preferred over dopamine?
In the past 10 years dopamine agonists have more often been considered as an initiating therapy in PD. Dopamine agonist therapy was chosen ahead of levodopa because it reduced the risk of motor complication development and probable neuroprotective effect.
Does levodopa increase dopamine?
Large levodopa-induced increases in synaptic dopamine concentration can lead to dramatic changes in receptor occupancy, which may be responsible for the emergence of peak-dose dyskinesias in Parkinson’s disease.
Why is carbidopa added to levodopa?
Carbidopa/levodopa remains the most effective drug to treat PD. In addition to helping prevent nausea, carbidopa prevents levodopa from being converted into dopamine prematurely in the bloodstream, allowing more of it to get to the brain.
Why is levodopa combined with carbidopa?
The combination of carbidopa and levodopa enhances levodopa’s potential of action because it enables the use of much lower doses of levodopa (80% less), which helps reduce the drug’s side effects, which include nausea and vomiting.
