Levodopa – the aromatic amino acid L-3,4–dihydroxy phenylalanine has held the attention of neurologists and pharmacologists alike for more than half a century. Even though extensive research has been done across the globe in treatment of Parkinson's disease, with different molecules, none could replace the gold standard treatment or provide complete relief for the debilitated. Although research brought us better tips and tricks to modulate the dopamine blood levels to balance between the desired and deleterious effects, it could never replace the basic substrate. From simple oral preparation to more advanced treatment like duodenal dopa administration for better efficacy and compliance, L-dopa has sure undergone scrutiny and stayed strong as the fundamental neurotransmitter replacement therapy to pave path for many more new therapeutic strategies. So as a token of gratitude to the revolutionary agent and pioneers behind it, a trip down the memory lane is in order.
