Magnesium in a Polyethylene Glycol Formulation Provides Neuroprotection After Unilateral Cervical Spinal Cord Injury

Abstract

MgCl₂ in a PEG formulation reduced secondary damage and improved behavioral recovery when administered 2 hours after a unilateral cervical hemicontusion injury. These findings are consistent with the neurologic benefit observed when administering this magnesium formulation in contusive and compressive models of thoracic SCI. Demonstrating the robustness of this neuroprotective effect in multiple injury models (and in the cervical injury model in particular) is important when considering the applicability of such a therapy for human SCIs.
