10% excreted unchanged by the kidney hepatic dysfunction Glimepiride: (Amaryl) monotherapy -- once a day administration or in combination with insulin most potent -- lowest dose of the sulfonylureas long duration of action: half-life = 5 hours hepatic metabolism: complete to inactive products Secondary Failure and Tachyphylaxis to Sulfonylureas: Treatment failures occur Possibly due to pancreatic B cell refractoriness or to loss of dietary compliance Combination of sulfonylureas and insulin would appear justified only in the presence of severe insulin resistance Biguanides Metformin: (Glucophage) Proposed Mechanism of Action: glycolysis stimulation-- increased glucose removal from blood decreased hepatic gluconeogenesis decreased glucose absorption rate from the GI tract reduced plasma glucagon in patients with refractory obesity and insulin resistance Advantages: does not cause hypoglycemia does not increased weight May be used in combination with sulfonylureas when sulfonylurea monotherapy is not effective Toxic/adverse effects: most common -- gastrointestinal (20% frequency) anorexia, nausea, vomiting, diarrhea dose-related usually occurs upon initiation of therapy -- often transient in effect Decreased vitamin B12 absorption

The iron chelator DFO has been shown to decrease ROS production, mitigate hemoglobin-induced neurotoxicity, reduce brain edema, and enhance functional outcomes in both in vivo and in vitro models of CH ( 3.6 Traumatic brain injury Traumatic Brain Injury (TBI) is followed by a cascade of secondary injuries, including the release of excitatory neurotransmitters and Fe 2+ , OS, LP, and the accumulation of ROS, all of which induce ferroptosis ( Additionally, miR-212-5p regulates prostaglandin-endoperoxide synthase-2 to reduce ferroptosis-induced neuronal death ( 3.7 Spinal cord injuries Spinal cord injuries (SCI), known for causing severe disability and mortality, present significant medical challenges worldwide
