In addition to its effects on the nervous system, magnesium sulfate reduces striated muscle contractions and inhibits acetylcholine release at the myoneural junction. It also reduces vascular resistance in high doses and prolongs SA node conduction time.

It also works to slow the rate of systolic dysfunction and diastolic dysfunction, which can help prevent cardiac arrest. This is one of the reasons doctors often give magnesium sulfate to women who have preeclampsia or eclampsia during pregnancy.
