Asthma-13

Treatment - Medical

The most effective treatment for asthma is identifying triggers, such as pets or aspirin, and limiting or eliminating exposure to them. If trigger avoidance is insufficient, medical treatment is available. Desensitization is currently the only known "cure" to the disease. Other forms of treatment include relief medication, prevention medication, long-acting β2-agonists, and emergency treatment.

The specific medical treatment recommended to patients with asthma depends on the severity of their illness and the frequency of their symptoms. Specific treatments for asthma are broadly classified as relievers, preventers and emergency treatment. The Expert Panel Report 2: Guidelines for the Diagnosis and Management of Asthma (EPR-2) of the U.S. National Asthma Education and Prevention Program, and the British Guideline on the Management of Asthma are broadly used and supported by many doctors. On August 29, 2007 the final Expert Panel Report 3: Guidelines for the Diagnosis and Management of Asthma was officially released. Bronchodilators are recommended for short-term relief in all patients. For those who experience occasional attacks, no other medication is needed. For those with mild persistent disease (more than two attacks a week), low-dose inhaled glucocorticoids or alternatively, an oral leukotriene modifier, a mast-cell stabilizer, or theophylline may be administered. For those who suffer daily attacks, a higher dose of glucocorticoid in conjunction with a long-acting inhaled β-2 agonist may be prescribed; alternatively, a leukotriene modifier or theophylline may substitute for the β-2 agonist. In severe asthmatics, oral glucocorticoids may be added to these treatments during severe attacks.

The discovery in 2006 by researchers at Harvard Medical School that asthma may be caused by over-proliferation of a special type of natural "killer" cell may ultimately lead to the development of better and more targeted drugs. Natural killer T cells seem to be resistant to the corticosteroids, one of the mainstays of current treatment. Other promising avenues of current research include using cholesterol-lowering drugs (statins) and fish oil supplementation to reduce airway inflammation.
