Intravenous infusion of magnesium sulfate and its effect on horses with trigeminal-mediated headshaking. [PDF]

, 2019
BackgroundTrigeminal-mediated headshaking results from low-threshold firing of the trigeminal nerve resulting in apparent facial pain. Magnesium may have neuroprotective effects on nerve firing that potentially dampen signs of neuropathic pain.
