Fosphenytoin sodium is a phenytoin prodrug with similar anticonvulsant properties.
Fosphenytoin is an effective neuroprotectant against ischemia-induced damage. In fosphenytoin (30 mg/kg, i.m.)-treated rat 5 min after ischemia episode, hippocampal CA1 pyramidal neurons remain at near control level (13.90 +/- 0.92), however, GFAP staining iss not significantly changed[1]. In fosphenytoin (84 mg/kg)-treated rat, the relative bioavailability of fosphenytoin is 83%. In fully kindled female Wistar rats, fosphenytoin dose-dependently increases the focal seizure (afterdischarge) threshold. Seizure severity and duration at threshold are reduced only after the highest does of fosphenytoin tested (84 mg/kg)[2].

Animal experiment: | A total of four groups of rats, including normal (n=2), sham operated (n=2), ischemia with saline-treated (n=2), and ischemia with fosphenytoin-treated (n=2), are studied. Postischemic rats in saline-treated and fosphenytoin-treated groups receive a single i.m. injection of saline or fosphenytoin (30 mg/kg), respectively, in the right hind limb 5 minutes after resuscitation. Sham-operated animals are treated similarly except for chest compression. All rats are killed on the 7th postischemic day by decapitation. Brains are immediately removed, bisected longitudinally, and immersed in 4% buffered neutral formaldehyde containing 0.25% glutaraldehyde for a minimum of 2 days at 4°C. Portions of the brain containing the dorsal hippocampus are coronally sectioned with a vibratome at 40 μm. With the aid of a dissecting microscope, rectangular blocks of about 1 mm2 in size encompassing the mid-CA1 region from sections that approximate Bregma -3.6 are dissected, postfixed in 2% osmium tetroxide, and dehydrated in ascending concentrations of ethanol before being embedded in Araldite 502. Sections of polymerized blocks 1 μm thick are cut and toluidine blue stained for light microscopic examination. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
