A Dutch toxicologist confirmed Monday he found traces of an non-prescribed drug in a blood sample taken from former Yugoslav President Slobodan Milosevic earlier this year.
Donald Uges said he was asked to examine the sample after Milosevic's blood pressure failed to respond to medication given by doctors at the UN detention center near The Hague, where he was being held during his war crimes trial.
Uges said he found traces of rifampicin, a drug that could have reduced the effectiveness of his other medications.
The rifampicin "makes the liver extremely active. If you're taking something (another medication) it breaks down very quickly," Uges told The Associated Press.
