Abstract

Objectives: To find the evolution in the billing of prescriptions for selective cyclooxygenase-2 (COX-2) inhibitors since they came on the market and to compare this evolution in primary care (PC) and specialist care (SC).Design. Cross-sectional, descriptive study.

Setting: Toledo Health Area. Main measurements. Data were obtained from the System of Drug Information (SIFAR) to analyse the monthly turnover of NSAID prescriptions (M01A group in the official classification of medicines, including rofecoxib and celecoxib) issued by doctors in PC and SC between January 2000 and June 2001.

Results: In our area during the study period, 583,558 NSAID packages were prescribed; 6.61% were COX-2 inhibitors, which represented 29.08% of NSAID expenditure. 98.23% of NSAID packages and 94.61% of COX-2 inhibitors were prescribed in PC. The use of COX-2 inhibitors in SC rose from 10.03% of the total NSAIDs in February 2000 to 29.79% in June 2001; whilst in PC it rose from 1.52% to 10.78%. Rofecoxib and celecoxib were third and fifth in the lists of most prescribed NSAIDs (number of packages) in SC, and ninth and twelfth in PC. In terms of cost of prescription, they were first and second in SC, and first and fourth in PC.

Conclusions: COX-2 inhibitors have become the main NSAIDs prescribed. The appearance of these drugs had a different impact on SC and PC doctors, with greater use of them and a more rapid introduction in SC.

Objetivo: Conocer la evolución en la facturación de recetas de los inhibidores selectivos de la ciclooxigenasa 2 (ICOX-2) desde su comercialización y comparar dicha evolución en los niveles asistenciales primario (AP) y secundario (AE).

Diseño: Estudio descriptivo transversal.

Emplazamiento: Área de Salud de Toledo.

Mediciones principales: Se obtuvieron del Sistema de Información Farmacéutica (SIFAR) datos para analizar la facturación mensual de las recetas de antiinflamatorios no esteroides (AINE) (grupo M01A de la clasificación oficial de medicamentos, que incluye rofecoxib y celecoxib) prescritas por los médicos de AP y AE entre enero de 2000 y junio de 2001.

Resultados: Durante el período de estudio, en nuestra área se prescribieron 583.558 envases de AINE; el 6,61% era ICOX-2, representando el 29,08% del gasto en AINE. El 98,23% de los envases de AINE y el 94,61% de ICOX-2 se prescribieron desde AP. El uso de ICOX-2 en AE pasó del 10,03% del total de AINE (febrero de 2000) al 29,79% (junio de 2001); mientras que en AP pasó del 1,52% al 10,78%. Rofecoxib y celecoxib ocupan el tercero y quinto puestos, respectivamente, en la lista de AINE más prescritos (número de envases) en AE, y el noveno y duodécimo en AP. En cuanto al coste de la prescripción, ocupan el primero y segundo puestos en AE y el primero y cuarto en AP.

Conclusiones: Los ICOX-2 han pasado a ocupar los primeros lugares en la prescripción de AINE. La aparición de estos fármacos ha tenido un impacto diferente entre los facultativos de AE y los de AP, observándose un mayor uso y una incorporación más rápida en AE.
