  • Patent number: 5395822
    Abstract: This invention discloses a method of using a salt of pyruvic acid (such as sodium pyruvate) to protect against neuronal degeneration due to ischemia (inadequate blood flow, which can be caused by stroke, cardiac arrest, or other events) or due to hypoxia, hypoglycemia, or cellular disorders which interfere with the energy metabolism of neurons. Treatment with pyruvate can be effective even when administered after the onset of an event that triggers neurodegeneration. A preferred mode of use involves co-administration of a pyruvate salt along with one or more agents that block NMDA and/or non-NMDA receptors, or with insulin or a thrombolytic agent.
