One is to treat inflammation of the airways by using inhaled corticosteroids. this pathway is considered preventive medicine, as the patient is administered the drug even when symptoms of asthma are not displayed. The other pathway is the inhalation of bronchodilators which relax the smooth muscles of the bronchioles this is used in cases of asthma attacks for immediate relief Genetic and environmental factors of asthma Through studies examining parent child relationships it was determined that a childs chance of getting asthma increased when both parents had asthma. this indicated there were hereditary factors in play. In a different study it was observed that in cases where one twin had asthma the other did not necessarily develop asthma as well. This demonstrates that not only are there are hereditary factors, but there are environmental factors as well, because if it was just hereditary then both twins must either develop asthma or not develop asthma. this is not the case As there is no one gene that is related to asthma, there are multiple genes inked to asthma. most of these genes are related to the immune system or inflammation. One such gene would be tGFB1 which plays an important role in control of expression of antibodies. Another gene would be aDAM33, which causes the bronchiole smooth muscles to be hypersensitive.
