Formoterol Solution: What Should I Do If I Miss a Dose?If you do not take your formoterol solution as scheduled, simply skip the missed dose and continue with your schedule as usual. Taking two doses too close together can increase the risk of side effects. Never double the dose of formoterol solution.
How Does Formoterol Solution Work?Normally, air moves easily into and out of the lungs through a network of airways. However, certain lung diseases (such as asthma or COPD) cause the muscles around these airways to tighten. This narrows the airways and makes it harder to breathe. This is called bronchospasm.
Formoterol solution is part of 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. Formoterol solution 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. Formoterol solution is a long-acting beta agonist.
