Magnesium sulfate (medical use) solution. In the United Kingdom 4 ml of 20% solution costs the NHS about 10.23 pounds. In the United States a course of medication typically costs less than $25. Magnesium sulfate is the primary treatment and preventative measure in women with eclampsia. It lowers systolic blood pressure while maintaining diastolic blood pressure, thus leaving blood flow to the fetus uncompromised.

Usage for prolonged periods (more than five to seven days) may result in health problems for the baby. In those at
Magnesium perchlorate Magnesium perchlorate Magnesium perchlorate is a powerful oxidizing agent, with the formula Mg(ClO). It is also a superior drying agent for gas analysis. Magnesium perchlorate decomposes at 250 °C. The heat of formation is -568.90 kJ mol. The enthalpy of solution is quite high, so reactions are done in large amounts of water to dilute it. It is sold under the trade name anhydrone. Manufacture of this product on a semi-industrial scale was first performed by G. Frederick Smith in his garage in Urbana Illinois, but later at a permanent facility in Columbus, OH called G. Frederick Smith Chemical Co.
