What If I Forget a Dose of Indacaterol Maleate?If you do not use your indacaterol maleate as scheduled, take it as soon as you remember. However, taking two doses too close together can increase the risk for side effects. Never take two doses of indacaterol maleate within the same 24-hour period.
How Does It Work?In normal, healthy lungs, air can move easily into and out of the lungs through a network of airways. However, certain lung diseases, including COPD, cause the muscles around these airways to tighten. This narrows the airways and makes it harder to breathe. This is called bronchospasm.
Indacaterol maleate belongs to a class of drugs called beta-adrenergic receptor agonists, or beta agonists for short. Beta agonists stimulate beta receptors in the body, including those on the muscles around the airways. This stimulation causes the muscles to relax, which opens up the airways and allows more air to get into and through the lungs. Indacaterol maleate also has some effects on decreasing the activity of mast cells in the lungs, which play an important role in inflammation and allergic reactions.
Beta agonists are usually divided into two categories: short-acting and long-acting beta agonists. Indacaterol maleate is a long-acting beta agonist (LABA). As a long-acting beta agonist, it is used on a scheduled basis to help prevent symptoms; it is not a "rescue" medication to be used as needed.
