Movement Disorders Clinical Practice, EarlyView.Abstract Background As Parkinson's disease (PD) progresses, motor fluctuations become increasingly difficult to manage with oral medications. Foslevodopa/foscarbidopa (LDp/CDp), delivered as a continuous 24‐h/day subcutaneous infusion, offers continuous levodopa delivery and stable plasma levodopa levels that reduce motor fluctuations. LDp/CDp has been
