The invention relates to the treatment of neurodegenerative diseases such as Parkinson patients with motor complications in need of Continuous Dopaminergic Stimulation. According to the invention a kit of pharmaceutical preparations is provided comprising levodopa and an AADC-inhibitor. Levodopa is applied via continuous subcutaneous infusion or by an oral modified release formulation and Continuous Dopaminergic Stimulation is achieved by almost complete inhibition of the peripheral levodopa metabolism. To reach far-going blockage of levodopa metabolism, an AADC-inhibitor (e.g., benserazide, carbidopa) is given orally in a much higher than normal dose and, as an indispensable prerequisite, the AADC-inhibitor has to be applied evenly distributed over the day. e.g., via a Modified Release formulation. In order to prevent levodopa conjugation over the COMT pathway, an oral COMT-inhibitor (e.g., opicapone) is also added. In addition, a drug-drug-interaction between the AADC-inhibitor and opicapone further increasing the activity of the former is likely to occur. The resulting effective inhibition of peripheral levodopa metabolism allows a marked reduction of the necessary (equivalent) levodopa (or prodrug) doses to 300-600 mg / day, which is, however, sufficient to reach high levodopa plasma levels of 1500 to 3000 ng / ml. The low daily levodopa dose is infused subcutaneously via minipump and is well-tolerated at the infusion site. Alternatively, the low daily levodopa dose is provided as an oral modified release formulation. The high steady-state levodopa plasma levels reached, allow effective Continuous Dopaminergic Stimulation-therapy for Parkinson's disease patients of any degree of severity. As additional benefit, the largely complete AADC-inhibition prevents the peripheral generation of dopamine and the cumbersome dopaminergic adverse effects (e.g., nausea, cardiovascular and gastro-intestinal adverse effects) are prevented.
