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 deficiency kidney, small intestine, and bone. In the acute phase of magnesium deficiency there is an increase in absorption in the distal small intestine and tubular resorption in the kidneys. When this condition persists, serum magnesium drops and is corrected with magnesium from bone tissue. The level of intracellular magnesium is controlled through the reservoir in bone tissue. Magnesium deficiency is not easy to directly measure. Typically the diagnosis is based on finding low blood magnesium levels (hypomagnesemia). Specifically by finding a plasma magnesium concentration of less than 0.6 mmol/L (1.46 mg/dl). Severe disease generally has a level of less than
