This review discusses the efficacy of clomethiazole (CMZ) in models of
global and focal ischemia, The fact that neuroprotection is demonstra
ble by using histological, biochemical, and functional measures is emp
hasised. The importance of the neuroprotection observed when the drug
is given after the ischemic insult and at doses that are safely tolera
ted by humans is discussed, with reference to requirements necessary f
or an experimental neuroprotective agent to be considered as a therape
utic drug for stroke. The biochemical pharmacology of CMZ is reviewed
and also evaluated with reference to the possible mechanism(s) by whic
h CMZ exerts its neuroprotective action. Finally, the clinical evidenc
e that CMZ protects against the neurological consequences of a major s
troke is outlined. (C) 1998 Elsevier Science Inc.
