ABSTRACT

Resumen El salbutamol es un agonista adrenérgico β2 ampliamente empleado en pacientes con enfermedades pulmonares obstructivas y restrictivas. Sus principales efectos secundarios son la taquicardia y el temblor. Las mioclonías son contracciones musculares involuntarias, irregulares, bruscas, breves y repentinas, y pueden ser generalizadas, focales o multifocales. Se presenta el caso de un paciente de 61 años con mioclonías de difícil manejo que solo presentó mejoría tras la suspensión definitiva del agonista adrenérgico β2. Se describen los hallazgos clínicos, las intervenciones y el resultado en las mioclonías asociadas con el uso de salbutamol y se discuten la posible génesis y la importancia de este efecto adverso. Para documentar el caso, se siguieron las recomendaciones de las guías para el reporte de casos (CAse REport, CARE). Aunque en diversos estudios se han descrito mioclonías secundarias al uso de diferentes fármacos, hasta donde se sabe, este sería el cuarto reporte de un caso asociado específicamente con el uso del salbutamol.


Abstract Salbutamol is a β2 adrenergic agonist widely prescribed in patients with obstructive and restrictive lung diseases. The main side effects associated with its use are tachycardia and tremor. Myoclonus is an involuntary, irregular, abrupt, brief and sudden muscular contraction, which can be generalized, focal or multifocal. We report the case of a 61-year-old patient presenting with myoclonus difficult to treat who showed improvement only after the definitive discontinuation of the β2 adrenergic agonist. We describe the clinical findings, the interventions, and the outcomes related to the onset of myoclonus secondary to the use of salbutamol, as well as the possible genesis and importance of this adverse effect. We used the CARE guidelines to delineate the clinical case. Although myoclonus secondary to the use of different drugs has been described in the literature, as far as we know this is the fourth report of salbutamol-induced myoclonus to date.
