The use of this class of drug earlier in the treatment cycle represents current theory, suggesting that many of the late treatment complications associated with PD treatment are a result of the short half-life of levodopa. [clevelandclinicmeded.com]

Levodopa still remains the gold standard of treatment of PD. However, long term treatment with levodopa is associated with response fluctuations, dyskinesias and psychiatric disturbances. [neurologyindia.com]

Even as L-Dopa’s effectiveness begins to decrease, it’s still better than no treatment at all. But newer and better treatments need to be developed. Unfortunately, we can’t fix the disease until we understand what’s causing it. [blogs.brandeis.edu]
