Where is magnesium sulphate found and whats is it used in?
Magnesium sulphate is commonly found in the oceans (10% of seawater salts). It is also found on land as the mineral epsomite (MgSO4.7H2O) in evaporitic salt deposits.
Magnesium sulfate, commonly known as Epsom salt, is a mineral. It works by replacing magnesium in the body and increasing water in the intestines. Magnesium sulfate can be used orally as a laxative to relieve occasional constipation, and to treat low levels of magnesium.
- Many of us are familiar with magnesium sulfate (Epsom salt), as it has been long used to soothe aches and reduce inflammation. Magnesium carbonate is an absorbent drying agent. It works as an astringent, providing toning, smoothing and skin-softening properties.
- Anticonvulsant action: Magnesium sulfate has CNS and respiratory depressant effects. It acts peripherally, causing vasodilation; moderate doses cause flushing and sweating, whereas high doses cause hypotension. It prevents or controls seizures by blocking neuromuscular transmission.
- Eclampsia is a leading cause of maternal mortality. Many drugs with anticonvulsant properties have been used to treat patients with pre-eclampsia and eclampsia. Magnesium sulfate is a significantly better drug than either diazepam or phenytoin for preventing recurrent seizures in eclamptic patients.
Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide).
- Magnesium oxide is used for relief of heartburn and sour stomach, as an antacid, magnesium supplement, and as a short-term laxative. It is also used to improve symptoms of indigestion. Side effects of magnesium oxide may include nausea and cramping.
- Properties of ionic compounds. Non-conductive in its solid state, but when dissolved in water or molten NaCl will conduct electricity. Because magnesium oxide stays solid at such high temperatures, it remains non-conductive. It is used for high-temperature electrical insulation.
- Each magnesium atom gives two electrons to an oxygen atom, so magnesium oxide is made of magnesium ions, Mg2+, and oxide, O2– ions. To make pure MgO, one way is to burn magnesium ribbon in pure oxygen, but metallic magnesium is quite expensive.
- Calcium chloride. Calcium prevents the deleterious cardiac effects of severe hyperkalemia that may occur before the serum potassium level is corrected. Because of its irritating effects when administered parenterally, calcium chloride is generally considered a second choice, after calcium gluconate.
- Prevention of hypermagnesemia usually is possible. In mild cases, withdrawing magnesium supplementation is often sufficient. In more severe cases the following treatments are used: Intravenous calcium gluconate, because the actions of magnesium in neuromuscular and cardiac function are antagonized by calcium.
- This medication is used to treat certain bone problems (e.g., Paget's disease, postmenopausal osteoporosis) and to reduce high blood levels of calcium. Calcitonin is a man-made hormone that works by slowing bone loss and maintaining normal calcium levels in the blood.
