Antidiuretic

Antidiuretic (pronunciation: an·ti·di·u·ret·ic, /ˌæntɪdaɪʊˈrɛtɪk/) is a term used in medicine to describe substances that help to decrease the production of urine by the kidneys, thereby reducing diuresis (increased or excessive production of urine).

Etymology

The term "antidiuretic" is derived from the Greek words "anti" meaning against, "dia" meaning through, and "ourein" meaning to urinate. Thus, it literally means "against urination".
