ABSTRACT
This report documents the occurrence of QT prolongation in a 57-year old man, on methadone replacement therapy, treated with azithromycin for community acquired pneumonia. This case highlights a hitherto unknown drug interaction. In light of ever-increasing use of azithromycin, it is imperative that azithromycin be used with caution in patients who are already on drugs that are known to cause QT prolongation or that cause torsades de pointes.
RESUMEN
Este reporte documenta la ocurrencia de la prolongación del intervalo QT en un hombre de 57 años, en la terapia de reemplazo con metadona, tratado con azitromicina por pulmonía adquirida en la comunidad. Este caso destaca una interacción de medicamentos desconocida hasta ahora. En vista del uso cada vez mayor de la azitromicina, resulta absolutamente necesario usarla con precaución en pacientes que ya están bajo tratamiento con medicamentos de los cuales se sabe que causan prolongación del intervalo QT o que causan torsades de pointes.
