Free radical spin traps exhibit properties consistent with a role in the pr
evention or amelioration of diseases mediated by the formation of free radi
cal species in excess of optimum constitutive requirements. At first view,
it may be surprising that they have not found a place in clinical medicine.
Some studies of diseases in which free radicals and oxidative stress are a
berrantly over- or underabundant and which might be ameliorated by inhibiti
ng or augmenting their formation have been reported. A number of pathophysi
ologic categories in which such agents have been or might be employed are b
riefly summarized.
