Prescribing pattern of anti-Parkinson drugs in Southern Italy: Cross-sectional analysis in the years 2003–2005

Aim of this study was to evaluate prevalence of use and prescribing pattern of Anti-Parkinson Drugs (APDs) in general practice of Southern Italy. Among 120,000 individuals registered in the lists of 93 general practitioners of Southern Italy, we estimated one-year prevalence and incidence of APD use in the years 2003–2005. Overall, prevalence of APD use remained stable over the years and it strongly increased in subjects over 70 years of age. L-Dopa with a dopa decarboxylase inhibitor was the most frequently prescribed APD, although the use of both ergot and non-ergot derivative DAs has increased, particularly, in the elderly. A high proportion of APD users (15–20%) received only one prescription during the study period.
