Antithrombotic effects of magnesium sulfate in in vivo experiments.

In this study, magnesium sulfate was effective in reducing the mortality of adenosine diphosphate-induced acute pulmonary thromboembolism in mice, when it was administered intravenously at doses of 100 and 200 microg/g body weight. In addition, intravenous injections of magnesium sulfate (100 and 200 microg/g) significantly prolonged bleeding time in the severed mesenteric arteries of rats by approximately 1.7- and 1.
