Current Litigation

Trasylol

On November 5, 2007, Bayer AG suspended worldwide sales of Trasylol, a clotting drug used during heart surgery to prevent bleeding, in response to concerns over a possible increased risk of death. The FDA requested such a removal after trials of the drug showed that the drug increased the risk of death, kidney damage, congestive heart failure and stroke.

What is Trasylol?

Trasylol works to slow or prevent bleeding, and is used to reduce blood loss and the need for blood transfusion during some types of heart surgeries. Commonly known as aprotinin, Trasylol is a naturally-occurring enzyme made from the lung tissue of cattle.

Side Effects of Trasylol

Trasylol has been associated with an increased risk of kidney failure, heart attack, stroke and other serious adverse events.
