Why is magnesium sulfate used for pre-eclampsia and eclampsia?
This drug typically is used in obstetrics to prevent severe pre-eclampsia from becoming eclampsia (life-threatening convulsions). It also is used to stop the convulsions of eclampsia. In the United States, it has been used to treat severe pre-eclampsia for 60 years (Lancet, 1997, Vol. 350, p. 1491) and is FDA-approved for this purpose.
