Natriumsitraatit

Natriumsitraatit, also known as sodium citrate, is a chemical compound with the formula Na3C6H5O7. It is a white, crystalline powder that is soluble in water. Sodium citrate is commonly used as a food additive, particularly as an acidity regulator and preservative. It is also used in the pharmaceutical industry as a buffering agent and in the treatment of hypercalcemia, a condition characterized by elevated calcium levels in the blood.

The compound is produced by reacting citric acid with sodium hydroxide. It is widely available and is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in food and pharmaceutical products. Sodium citrate is often used in combination with other sodium salts, such as sodium bicarbonate, to maintain the pH balance in various applications.

In the medical field, sodium citrate is used to chelate calcium ions, which helps to prevent the formation of blood clots during certain medical procedures, such as hemodialysis. It is also used in the treatment of hypercalcemia, where it helps to lower calcium levels in the blood. Additionally, sodium citrate is used in the preparation of intravenous fluids and as a component in some antacid medications.

Despite its widespread use, sodium citrate can have side effects when used in high doses. These may include gastrointestinal discomfort, such as nausea, vomiting, and diarrhea. In rare cases, it can also cause allergic reactions. Therefore, it is important to use sodium citrate under the guidance of a healthcare professional.
