Brief Summary:
Magnesium sulphate is an inorganic salt with multiple therapeutic applications in medicine it has been widely utilized and studied on a diverse set of conditions such as asthma, cardiac arrhythmia and stroke. In pregnant women ,MgSo4 has been used in many cases such as for seizures prophylaxis in preeclampsia, tocolysis in preterm labour and for fetal neuroprotection in immenint preterm delivery.MgSo4 has been used as the standard drug for tocolysis in preterm labour and other drugs have been compared to it.
