ABSTRACT
Allopurinol has been used in the management of hyperuricemic states for several years. Despite its efficacy for these indications, recent concerns have been raised regarding the unnecessary morbidity and mortality occasionally associated with its inappropriate use. In an effort to assess the utilization of allopurinol a concurrent drug utilization review was undertaken. Fifty patients who were prescribed allopurinol were entered into the study and underwent health record review and patient interview, to determine appropriateness of therapy and the need for educational intervention. A number of inconsistencies with regard to established guidelines were identified. As well, 11 of 50 patients (22%) required intervention because of either lack of indication or excessive dose. Fifty-five percent of the educational interventions, performed by the pharmacist, were accepted as written. The current utilization of allopurinol at our facility differs substantially from guidelines developed for optimal utilization of allopurinol. Further, a pharmacy based intervention program can improve prescribing practices of allopurinol.
RÉSUMÉ
On emploie l'allopurinol pour traiter l'hyperuricémie depuis plusieurs années. Récemment, malgré l'efficacité du médicament, on a exprimé des inquiétudes quant à la morbidité et à la mortalité occasionnellement associées à un emploi inapproprié. Pour les vérifier, on a effectué une étude sur l'emploi simultané de médicaments. Ont participé à cette étude 50 malades à qui on avait prescrit de l’allopurinol. On a passé leurs dossiers de santé en revue et on les a interrogés afin de déterminer si le traitement était approprié et si des mesures éducatives se justifiaient. Plusieurs divergences ont été révélées par rapport aux directives établies. En outre, il a fallu intervenir auprès de 11 patients (22%) parce que le traitement n'était pas indiqué ou parce que le dosage était excessif. Cinquante-cinq pour cent (55%) des interventions éducatives des pharmaciens ont été acceptées. À l'heure actuelle, la prescription de l'allopurinol dans notre établissement s'écarte sensiblement des directives élaborées pour garantir l'utilisation optimale du médicament. De plus, un programme d'intervention développé par le pharmacien peut améliorer les pratiques concernant l'utilisation de l'allopurinol.Downloads
