Magnesium sulfate may act as a vasodilator, with actions in the peripheral vasculature or the cerebrovasculature, to decrease peripheral vascular resistance or relieve vasoconstriction. Magnesium oxide acts as an antacid or as an osmotic laxative . Administration of magnesium can be divided into FDA versus non-FDA approved. Its pharmacologic mechanisms of action are different from other classes of oral antihyperglycemic agents. Some people use it as an antacid to relieve heartburn, sour stomach, or acid indigestion. mechanism by which the headache phase develops from the aura is unknown and somewhat controversial, but the first phase may be related to the cortical release of CGRP, nitric oxide, arachidonic acid or various ions and their effects via the trigeminal nerve into the brainstem and back to the dural blood vessels [34,35]. Hypermagnesemia (serum magnesium concentrations >2.5 mEq/L) may depress the CNS and block peripheral neuromuscular transmission, producing anticonvulsant effects. chloroquine.
