What is a dependent variable? In math, a dependent variable is one in an expression, equation or function that depends upon one or more other variables' values to determine its value. The dependent variable is usually isolated on one side of an equation. For example, x is the dependent variable in the equation x=y+1.
Atrovent (ipratropium) is a bronchodilator that relaxes muscles in the airways and increases air flow to the lungs. Atrovent is used to prevent bronchospasm, or narrowing airways in the lungs, in people with bronchitis, emphysema, or COPD (chronic obstructive pulmonary disease). Atrovent may also be used for purposes not listed in this medication guide. You should not use Atrovent if you are allergic to ipratropium or atropine.
