From AP, Reuters, Yahoo and others:
Bayer AG last week voluntarily stopped worldwide sales of its antibleeding drug Trasylol after a Canadian clinical study found it could be linked to a higher risk of death than other drugs.
Trasylol, also known as aprotinin, works by blocking enzymes that dissolve blood clots. It is designed to stem blood loss and enable patients receiving heart bypass surgery to avoid transfusions. The FDA approved Trasylol in the 90's. At least two studies found an alleged link between its use and kidney problems, heart attacks and strokes. There have been reports of renal failure tied to the drug's use. Stay tuned.
