Objectives We aimed to investigate the efficiency of controlled-release levodopa/benserazide (Madopar HBS) use during daytime in our pilot study on advanced-stage Parkinson's disease (PD) subjects with deep brain stimulation of the subthalamic nucleus (STN-DBS) therapy.

Methods We have evaluated all PD subjects with STN-DBS who had admitted to our outpatient polyclinic between February 2022 and March 2022. Among these patients, those who were taking levodopa therapy at least five times throughout the day and the efficiency of levodopa lasted less than 3 hours were detected. The standard levodopa therapy was switched to Madopar HBS in all patients who accepted the therapy chance and the clinical evaluation of the patients on Madopar HBS therapy was performed in the second month of the therapy.

Results Ultimately, the follow-up of all four patients in whom the levodopa therapy was changed to Madopar HBS yielded a significant reduction in the “off” periods and improvement in the PSQ-39 scores.

Conclusion We suggest the use of Madopar HBS in PD patients with STN-DBS surgery suffering from motor fluctuations, particularly in the subgroup with milder dyskinesias. Future study results of a large number of PD subjects with STN-DBS therapy are warranted to confirm our observations. The results of these studies may provide critical applications in clinical practice.
