A drug that causes urination is called a __________.

A drug that causes urination is referred to as a diuretic. Diuretics work by promoting the elimination of water and salts from the body through urine. They are commonly used in medicine to manage conditions such as high blood pressure, edema, and certain kidney disorders. By increasing urine output, diuretics help to reduce fluid buildup and lower blood pressure, making them a crucial component of treatment for patients with these health issues.

The other terms refer to different types of medications that serve distinct purposes. An antitussive is used to suppress coughing, typically for relief from a cough caused by a cold or respiratory infection. An appetite suppressant aims to reduce hunger and assist with weight management. An antipyretic is used to reduce fever, often by lowering the body’s temperature. Each of these drugs has a specific function unrelated to promoting urination, which is why diuretic is the correct term for this question.
