Conclusions
TH inhibitors down-regulate DA levels and protect DA neurons, while DA receptor agonists function to activate post-synaptic DA receptors to alleviate PD symptoms. NAC and anticholinergic drugs may be added to improve therapeutic effects. A multi-drug combination therapy including TH inhibitors should be further explored in clinical trials in PD patients.
