ABSTRACT
Dipyrone (or metamizole) is an analgesic and antipyretic for oral or parenteral administration. Its action mechanism is directly related to the inhibition of the signaling of TRPA1 (Transient Receptor Potential Ankirin 1). The TRPA1 ion channel, located in the plasma membrane of a subpopulation of nociceptors, plays a major role in pain transmission.1-3 However, the clinical use of dipyrone is associated with various adverse effects such as agranulocytosis, aplastic anemia, anaphylaxis, toxic epidermal necrolysis, renal failure, upper gastrointestinal tract bleeding, induction of acute attacks of porphyria, among others.4-7 One study also reported an increased risk of leukemia in children born to mothers who took dipyrone during pregnancy.
RESUMEN
La dipirona (o metamizol) es un analgésico y antipirético para administración oral o parenteral. Su mecanismo de acción está directamente relacionado con la inhibición de la señalización de TRPA1 (Transient Receptor Potential Ankirin 1). El canal de iones TRPA1, localizado en la membrana plasmática de una subpoblación de nocioceptores, tiene una función primordial en la transmisión del dolor.1­3 Sin embargo, el uso clínico de la dipirona se asocia a diversos efectos adversos como agranulocitosis, anemia aplástica, anafilaxia, necrolisis epidérmica tóxica, insuficiencia renal, sangrado de tracto gastrointestinal superior, inducción de ataques agudos de porfiria, entre otros.4­7 Un estudio reportó también un incremento en el riesgo de leucemia en niños nacidos de madres que consumieron dipirona durante el embarazo.
