Clinical Trial Summary

The present study is part of a project titled 'Magnesium in asthma and chronic obstructive pulmonary disease'. The hypothesis of the main project is that daily magnesium supplement will benefit patients with asthma and chronic obstructive pulmonary disease.

The aim of this part of the project is to study the pharmacokinetics of the following two magnesium supplements:

• Mablet (dietary supplement)

• Magnesium Sulfate (solution for infusion)
