What is Magnesium hydroxide - Meaning and definition

Published by Roberto Wenk. Reviewed by Alison Ramsey. Last updated date: January 9, 2019.

A solution of magnesium hydroxide with antacid and laxative properties.
Milk of Magnesia exerts its antacid activity in low doses such that all hydroxide ions that enter the stomach are used to neutralize stomach acid. This agent exerts its laxative effect in higher doses so that hydroxide ions are able to move from the stomach to the intestines where they attract and retain water, thereby increasing intestinal movement (peristalsis) and inducing the urge to defecate.
