Efecto de la digoxina sobre la insuficiencia cardíaca
Aunque el tratamiento con digoxina incrementa la supervivencia en pacientes con insuficiencia cardíaca, esto sólo ocurre cuando los niveles del fármaco en sangre se mantienen en un mínimo. Sin embargo, tampoco se puede aumentar tales niveles porque entonces la terapia ya no es beneficiosa e incluso es potencialmente peligrosa para los pacientes.
Esta es la conclusión de un estudio publicado en "JAMA" por el Digitalis Intervention Group (DIG), con una muestra de 3.782 pacientes varones. Los resultados indican que la dosis de digoxina que contribuye a aumentar la supervivencia es la que da lugar a concentraciones en sangre del fármaco entre 0,5 y 0,8 ng/ml.
