[The prevalence and pharmacological cost of Parkinson's disease in Spain].
BACKGROUND
Parkinson's disease is the second most frequent neurodegenerative disease.


OBJECTIVE
To analyze the dispensation of antiparkinsonian agents in Spain and to estimate the Parkinson's disease prevalence.


METHODS
Dispensation of antiparkinsonian agents were studied in Spain during two years (October 1998 to September 2000). Results were expressed in defined daily dosages per 1,000 inhabitants per day (DID). Levodopa's DID was used to estimate the prevalence of the disease. The cost per 1,000 inhabitants per day (CID) and the daily treatment cost was also valued.


RESULTS
The most frequently used drugs are levodopa, biperiden and selegiline. The total cost reached values of 116,346,589.30 euros during the study period. The CID was 4,14 euros. It was very high the daily treatment cost of pramipexol and entacapone. The prevalence of Parkinson's disease is considered in 1.7 per 1,000 inhabitants in Spain. There is an important geographical variability; regions as Castilla-Leon, Galicia and La Rioja have a higher prevalence than Andalucia or Murcia. The number of patients in Spain can be considered in 69,571 people.


CONCLUSIONS
There are some differences between the autonomous communities in the antiparkinsonian drugs' utilization.
