Is there a place for nebulised magnesium sulphate in the management of asthma?

Intravenous magnesium sulphate (MgSO4 ) is an accepted part of the pharmacological management of patients with asthma. There is conflicting information, however, on whether its nebulised form is beneficial. This article describes a case study in which a patient was given intravenous MgSO4 . It was suggested by a medical consultant that she could have been given nebulised MgSO4 , so a literature review was undertaken to examine its efficacy. The results suggest there is no evidence to support the use of nebulised MgSO4 in the management of patients with asthma.
