Treating Asthma: Personalized Medicine
Are you getting care that's right for your body, your age, and your background?
Customizing Your Asthma Treatment
Because asthma is such a changeable disease, with so many different triggers and symptoms, finding the best treatment can be tricky. Even the most basic medical needs -- like the frequency of checkups -- can vary a great deal from person to person.
"It's really difficult to standardize how often a person with asthma should schedule appointments," says Bernstein. "A person with mild intermittent asthma may only need an appointment once a year. Someone with very severe asthma may need to go in once every two weeks." It all depends on your particular condition.
Asthma medicines are not interchangeable. "Some treatments work well for certain subgroups and some don't," says Windom. "But right now we don't have ways of testing beforehand what will work best." The foundation of asthma treatment is the use of prevention medications, which are used daily to keep symptoms from worsening. Inhaled corticosteroids -- such as Advair (a corticosteroid combined with a long-acting bronchodilator) and Flovent -- are examples of inhaled steroids. A newer class of long-acting drugs is leukotriene modifiers, such as Accolate, Singulair, and Zyflo.
As effective as these medicines are at controlling asthma, they essentially treat the symptoms of asthma or block the effects of specific allergens. One type of treatment stops the underlying cause of asthma symptoms. The only drug of this class available, Xolair, blocks the effects of IgE, a molecule that can trigger asthma symptoms. IgE is overproduced when the body is exposed to allergens.
As researchers learn more about the antibodies that trigger the symptoms of asthma, Windom predicts that drug companies will develop more medications to block their effects. So rather than having one "wonder drug" that controls everyone's asthma, we could have several different ones designed to help different groups of people.
Becoming a Proactive Asthma Patient
Keep in mind that getting a personalized treatment plan for your asthma isn't just your doctor's responsibility. You have an important role to play too. "People really need to be proactive patients," says Bernstein.
Blaiss agrees. "Patients have to partner up with their doctors if they want to get the best care," he tells WebMD.
Being a partner in your health care requires some work on your part. Most important, you have to be sure to give your doctor all of the relevant information. A lot of people forget -- or don't bother -- to mention to their doctor that they had changes in their asthma symptoms.
"If the doctor doesn't know that your symptoms have changed, he might just keep refilling the old prescriptions, even if they're not helping," says Blaiss.
So before your next appointment -- prepare. Take a hard, objective look at your health. Since your recollection may not be totally accurate, you might want to start keeping a journal of your symptoms.
