Role of MgSO4 in Respiratory Diseases
Magnesium sulfate (MgSO4) is a bronchodilator. It relaxes the bronchial muscles and
expands the airways, allowing more air to flow in and out of the lungs. This can relieve
symptoms of asthma, such as shortness of breath. Doctors mainly use MgS04 to treat people
who are having severe asthma flare-ups.
MgSO4 has been considered an adjunct therapy for severe and life-threatening asthma
exacerbation
How does MgSO4 work?
Magnesium may have a role in managing asthma through its dual effect as an anti-
inflammatory and broncho-dilating agent. You may receive MgSO4 intravenously, which
means through an IV, or through a nebulizer, which is a type of inhaler. According to a
research review published in the journal Asia Pacific Allergy Trusted Source, evidence
suggests that MgSO4 is useful for treating severe asthma attacks when people receive it
through an IV. Fewer studies have found that nebulized MgSO4 is useful. More research is
needed.
Intravenous MgSO4 infusion has been advocated in the past for the treatment of acute
asthma. Magnesium can relax smooth muscle and hence may cause bronchodilation
by competing with calcium at calcium-mediated smooth muscle ̶ binding sites.
Usually, 1 gram or a maximum of 2.5 grams during the initiation of therapy may be
considered.
Inhaled MgSO4 has generated some interest in the treatment of status asthmaticus
when combined with beta-agonist use
Magnesium can induce bronchial smooth muscle relaxation in a dose-dependent manner by
inhibiting calcium influx into the cytosol, histamine release from mast cells, or acetylcholine
release from cholinergic nerve endings. It also may increase the bronchodilator effect of β2-
agonist by increasing the receptor affinity
Magnesium isn’t a recommended first-line treatment for asthma. MgSO4 may help stop an
acute asthma attack
