Asthma is a chronic (long-term) condition of the airways. Inflammation (swelling) and the tightening of the airways can lead to wheezing, coughing, and difficulty breathing. This is because the air cannot flow through your lungs properly.

What is the most common type of asthma?
Allergic asthma is the most common type. It is the result of your body's response to environmental allergens, substances that trigger allergies.Your body produces proteins called immunoglobulins (IgE) to try to control these allergens. IgE will then cause a release of chemicals, which can lead to the tightening of your airways and eventually inflammation.

How do asthma medications work?
There are several types of medications used to reverse these effects on your airways. Some medications are used to treat an acute attack, such as albuterol. Other medications are for the long-term treatment of asthma to cut the number and severity of attacks. For some people, inhalers and oral medications are not enough to treat their asthma.

Is there a medication with a unique mechanism of action currently available?
Yes. Currently, there is Xolair® (omalizumab), the first IgE blocker developed to reduce the attacks and symptoms of allergic asthma. This medication is given as an injection, usually every month, for people with moderate to severe asthma associated with yearlong allergies. Most patients have these shots given to them by their doctor or nurse. Although Xolair is usually well tolerated, side effects are possible. It is important to know when they are happening and how to manage them, especially if they are serious, so you can contact your doctor.
