What is the common use of Milk of Magnesia in medical practice?

Milk of Magnesia is commonly used as an antacid due to its ability to neutralize stomach acid, which can help relieve symptoms associated with heartburn and indigestion. Its active ingredient, magnesium hydroxide, works by reacting with the acid in the stomach to form magnesium chloride and water, thereby reducing acidity. This property makes it effective in alleviating discomfort caused by excess stomach acid.

In addition to its role as an antacid, Milk of Magnesia is also used as a laxative, promoting bowel movements by drawing water into the intestines. While it serves multiple purposes, its primary and most common use in a medical context is as an antacid. This is why the identification of Milk of Magnesia as an antacid reflects a fundamental understanding of its therapeutic applications.
