  • Title: Neuroprotective therapy.
    Author: Hickenbottom SL, Grotta J.
    Journal: Semin Neurol; 1998; 18(4):485-92. PubMed ID: 9932619.
    Abstract:
    The concept of neuroprotection relies on the principle that delayed neuronal injury occurs after ischemia. The phenomenon of the "ischemic cascade" has been described, and each step along this cascade provides a target for therapeutic intervention. In animal models of global and focal cerebral ischemia, numerous preclinical studies have demonstrated various agents to be neuroprotective at different steps along this cascade. A wide variety of drugs has also been studied in humans. Ten classes of neuroprotective agents have reached phase III efficacy trials but have shown mixed results. They include calcium channel antagonists, NMDA receptor antagonists, lubeluzole, CDP-choline, the free radical scavenger tirilizad, anti-intercellular adhesion molecule-1 (ICAM-1) antibody, GM-1 ganglioside, clomethiazole, the sodium channel antagonist fosphenytoin, and piracetam. In the future, clinicians may have an armamentarium of treatments for acute ischemic stroke at their disposal, with a combination of agents directed at different sites in the ischemic cascade being the ultimate goal.
