Impact of new-generation agents on antiepileptic drug prescribing patterns in a residential ICF-MR facility.
OBJECTIVE
Describe the impact of newer antiepileptic drugs (AEDs) on prescribing practices in a large, residential intermediate-care facility for the mentally retarded (ICF-MR), with onsite clinical pharmacist support services, over a 15-year period.


METHODS
All residents at the facility receiving AEDs for management of seizure disorder were included in this retrospective assessment. Number and type of AEDs used per individual were recorded and analyzed over the 15-year interval. Current prescribing practices were evaluated regarding rational polytherapy prescribing trends.


METHODS
400-bed residential ICF-MR for the severe to profoundly mentally retarded.


METHODS
All individuals residing at the ICF-MR facility receiving AED therapy for a seizure disorder. Residents were primarily in the severe to profound range of developmental disability, with multiple medical comorbidities.


METHODS
Clinical pharmacists actively participate in all treatment teams and monthly neurology clinic to promote and encourage rational pharmacotherapy.


METHODS
Prescribing trends related to AED therapy were followed over a 15-year period. Comparisons were made regarding monotherapy and polytherapy at multiple-year intervals, with specific emphasis on how the newer generation AEDs have affected use of older medications.


RESULTS
Overall trend from 1988 suggests more monotherapy and less use of barbiturates. Introduction of a new generation of AEDs has not affected the overall trend toward one- or two-drug regimens over the period in review.


CONCLUSIONS
The relative stability of the number of AEDs per resident during the introduction of a new generation of AEDs suggests that as new drugs are added, ineffective or problem-prone drugs are discontinued.
