Magnesium sulfate in oxidative stress-associated pathologies: clinical, cellular, and molecular perspectives
Abstract
Magnesium sulfate (MgSO₄) is a therapeutically versatile agent used across various medical conditions. This review integrates experimental and computational findings to elucidate the clinical, cellular, molecular, and electronic mechanisms underlying MgSO₄'s therapeutic effects, focusing on its antioxidant properties. MgSO₄ remains the gold standard treatment for preeclampsia and eclampsia, preventing seizures and mitigating oxidative damage. In preterm birth, it offers fetal neuroprotection, although its efficacy as a tocolytic agent is limited. MgSO₄ also shows promise in treating respiratory conditions, notably severe asthma, where it acts as a bronchodilator. Its applications extend to anesthesia, pain management, and cardiac arrhythmias, reflecting its diverse pharmacological actions. Advanced computational methods, including molecular dynamics simulations and quantum chemistry calculations, have revealed how MgSO₄ interacts with cell membranes and neutralizes hydroxyl radicals. These studies suggest that MgSO₄'s antioxidant effects stem from its ability to stabilize membrane structures and modulate electron transfer processes. The therapeutic effects are mediated through multiple pathways, including calcium channel modulation, NMDA receptor antagonism, and anti-inflammatory mechanisms. Although generally safe, MgSO₄ requires careful monitoring due to its narrow therapeutic window. Future research should focus on precision dosing strategies, innovative delivery systems,…
