Article information

Los antitiroideos de síntesis son fármacos de uso muy frecuente en el tratamiento del hipertiroidismo. Presentan con frecuencia reacciones adversas en la piel y es también muy conocida su capacidad, mucho más rara, de provocar agranulocitosis. También es habitual que puedan causar elevaciones asintomáticas y autolimitadas de transaminasas; sin embargo, son muchos menos los casos descritos de hepatotoxicidad con repercusiones clínicas. Presentamos el caso de una paciente con hepatitis tóxica aguda secundaria a la toma de metimazol, que se manifestó como ictericia colestásica.

Palabras clave:
Metimazol
Ictericia colestásica
Hepatitis aguda
Tionamidas

Thionamides are drugs currently used in the treatment of hyperthyroidism. They often cause side effects in skin, and agranulocytosis is a rare but serious complication of thionamide therapy. They are also often associated with mild transient increase of serum aminotransferase concentrations, but there are very few cases in the literature of severe hepatotoxicity. We report the case of a patient with acute toxic hepatitis due to methimazole, which presented as cholestatic jaundice.

Key words:
Methimazole
Cholestatic jaundice
Acute hepatitis
Thionamides
