Safinamide (Xadago) is an add-on medicine that may be prescribed when individuals taking levdopoa and carbidopa have a breakthrough of Parkinsons symptoms that were previously under control. "We have demonstrated that the use of the tyrosinase-expressing tomatoes as a source of L-DOPA is possible. The drug gained approval in the EU last December following a 2 year study in people with mid to advanced Parkinson's who were already taking levodopa. Chaplin, S. Safinamide: Add-on Therapy for Parkinson’s Disease. Feb 3, 2020 - Explore Parkinson's Viewpoint | Parkin's board "New Drugs for Parkinson's Disease", followed by 2003 people on Pinterest.

According to author Peter Jenner:, "The introduction of L-Dopa [levodopa] in those with longer disease duration or in high doses may result in a shortened period of good effect before motor complications appear.

In the new study, lab mice that grew new neurons also showed improvements in Parkinson-like movement problems. It's a further demonstration of tomato as a strong option for synthetic biology. One new study addressed the “wearing off” effect of levodopa, the most common drug treatment for Parkinson’s.The effect occurs in patients who have been taking the drug … Like selegeline and rasagaline, safinamide is a type of MAO-B inhibitor, which prevents the breakdown of dopamine and thus increases its levels in the brain.

Safinamide could be a better add-on therapy to primary treatment with levodopa than other add-on treatments, including other MAO-B inhibitors as well as COMT inhibitors. Scientists have genetically modified a tomato to produce L-DOPA, a drug used to treat Parkinson’s disease. News-Medical spoke to researchers about their latest research into beta-blockers, and how they could potentially be used to treat COVID-19. 2017;20(3):190-198. doi:10.4103/aian.AIAN_239_17, Jenner P.
