In asthma, the smooth muscles around the airways can become hyper-reactive. The prescription medications Singulair, Advair
, and Serevent all work, in part, by dilating the smooth muscles around the airways. However, all of these medications
are associated with a host of serious side effects. Magnesium, however, can result in the dilation of the smooth muscles around the airways with no serious adverse effects and much less cost. The most serious adverse effect with magnesium is diarrhea.
