RESUMEN
La exenatida, o exendina-4 sintética, es un nuevo medicamento antidiabético, agonista del GLP-1 (péptido similar al glucagón-1) que restaura el efecto incretina que se encuentra casi perdido en los pacientes con diabetes mellitus tipo 2. El fármaco, que se aplica por vía subcutánea dos veces al día, incrementa la secreción de insulina consecutiva a la ingestión de glucosa, reduce la hipersecreción de glucagón, retarda el vaciamiento gástrico, disminuye el consumo de alimentos y el peso corporal, y controla eficazmente la hiperglucemia posprandial y en ayuno. En animales de experimentación también causa elevación del número de las células β pancreáticas. Su principal efecto adverso es la aparición de náuseas. Este medicamento está indicado en diabéticos tipo 2 en quienes no se haya logrado controlar la glucemia con dieta e hipoglucemiantes orales. Las diversas acciones terapéuticas de la exenatida parecen ideales para el tratamiento de la diabetes tipo 2 y alientan la esperanza de modificar la evolución de este padecimiento.
