Magnesium and Platelet Function Testing
Belgium20 participantsStarted 2017-06-09
Plain-language summary
Magnesium has built up the reputation of a 'natural calcium antagonist'. However, the exact effect of magnesium on coagulation and more specifically on platelet function is still disputed. An important discrepancy between in vivo and in vitro studies exists. Magnesium has thus been reported to antagonize platelets in some studies, and to stimulate platelets in other studies. Current evidence seems to point in the direction of a general antagonization of aggregation and coagulation.
Intravenous magnesium is often administered in pre-eclampsia as seizure prophylaxis. Therapeutic regimens usually consist of an intravenously administered loading dose (2-3 grams) and a maintenance infusion, targeting a plasma level of 2-3 mmol/L. Therapeutic drug monitoring is needed, as magnesium toxicity is an important concern.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
