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. Magnesium sulphate was once used as a tocolytic, but meta-analyses have failed to support it as an anti-contraction medication. Usage for prolonged periods (more than five to seven days) may result in health problems for the baby. In those at
Magnesium the commercial aerospace industry, magnesium was generally restricted to engine-related components, due to fire and corrosion hazards. Currently, magnesium alloy use in aerospace is increasing, driven by the importance of fuel economy. Development and testing of new magnesium alloys continues, notably Elektron 21, which (in test) has proved suitable for aerospace engine, internal, and airframe components. The European Community runs three R&D magnesium projects in the Aerospace priority of Six Framework Program. In the form of thin ribbons, magnesium is used to purify solvents; for example, preparing super-dry ethanol. Both AJ62A and AE44 are recent developments in high-temperature low-creep magnesium
