Other Treatments
Various drugs are being investigated for asthma treatment. Some of these drugs have anti-inflammatory effects, which may help reduce dependence on corticosteroids. For example, etanercept (Enbrel), which blocks the inflammatory protein called tumor necrosis factor alpha, is being investigated for patients whose asthma has not responded to other drugs. The humanized monoclonal antibody daclizumab has also improved asthma control in patients with treatment-resistant asthma, as well as patients with moderate to severe chronic persistent asthma. Certain antibiotics, such as clarithromycin (Biaxin), may improve lung function in patients with asthma who show evidence of infection with the bacterial organisms Mycoplasma or Chlamydiapneumoniae. Dapsone, a drug known as a sulfone, is also under investigation.
Alternative Treatments
Alternative therapies are being widely used by children, adolescents, and adults with asthma. In one study, nearly half of asthma or allergy sufferers resorted to alternative treatments. To date, however, evidence does not support any value from most alternative therapies, including high-dose vitamins, urine injections, homeopathic remedies, and most herbal remedies.
Relaxation and Stress-Reduction Techniques. Patients report benefits from many stress reduction techniques, such as acupuncture, hypnosis, breathing relaxation techniques, massage therapy, and meditation practices.
The Buteyko Breathing Method. The Buteyko breathing method is an experimental approach designed to increase levels of carbon dioxide in the body. To do this, patients are trained to reduce their volume of breath and to avoid hyperventilation (over-breathing). Some studies are reporting that patients using this method reduce their use of medications and improve their quality of life. The system originated in Australia and is not yet widely available in the U.S.
