PMID 40985570WHAT IT FOUND
People with Parkinson's disease outside major cities had different medication prescription patterns, with lower levodopa combination use and higher pramipexole in some regions.
This describes prescribing differences, not patient outcomes.
Key findings
01In 1676 people with self-reported Parkinson's disease, PD medication prescribing was related to geographical location and age group.
02Levodopa and levodopa combination medications accounted for 75.5% of prescriptions in major cities, 70.3% in inner regional areas, and 74.1% in outer and remote regions.
03Pramipexole accounted for 14.2% of prescriptions in major cities, 18.2% in inner regional areas, and 15.2% in outer and remote regions.

What it does not show
Participants had to be able to complete the survey, so the sample likely reflects people living in the community rather than those in later-stage residential healthcare. Parkinson's disease status was self-reported, not confirmed by a documented medical diagnosis. The study could not link mortality, time since diagnosis, or time of diagnosis information. The analysis did not include the geographic distribution or type of prescriber, such as GP, neurologist, or geriatrician. Relocation between 2004 and 2017 was not accounted for in the statistics. Some geographic subgroups were small and merged for analysis, and the 85 and over group was omitted from some medication tables because expected cell counts were too low. Entacapone prescriptions may be underestimated because it can be prescribed as a combination drug with levodopa.
Declared interests
The authors declared no conflicts of interest. Charles Sturt University funded the work.
The easy way to misread this
Do not read these prescription differences as evidence that one medication works better or that rural care is worse. The study linked self-reported Parkinson's disease to prescription records, did not analyse prescriber type, diagnosis date, or patient outcomes, and cannot show why the patterns differ.
