Treatment of intracerebral hemorrhage is often pointless, although considerable effort has been devoted to developing treatments for ischemic stroke. The purpose of this study was to determine the influence of drugs in improving neurological outcomes with pharmaceutical therapy after intracerebral hemorrhage. The free-radical hypothesis for intracerebral hemorrhage is based on the cytotoxicity triggered by blood components and its degradation products, such as heme and iron as a potent pro-oxidant atom. Sulfaphenazole (SPZ) has a different mechanism such as reactive oxygen species scavenging, in addition to the inhibition of superoxide production by cytochrome P450. The present study investigated the properties of SPZ in collagenase-induced intracerebral hemorrhage rat brain damage. The results show that systemic SPZ treatment after intracerebral hemorrhage reduces striatal dysfunction, the elevation of lipid peroxidation, and brain edema in the rat. These results suggest that SPZ is a potentially effective therapeutic approach for intracerebral hemorrhage as the effect of SPZ was initiated for either 1 h or 3 d post-intracerebral hemorrhage.
