Drugmaker Bayer AG has agreed to settle about 200 of 2,000 cases in which plaintiffs alleged that the use of Trasylol to control bleeding during their heart surgeries caused injuries such as kidney failure and fatal heart problems.

One Pennsylvania lawyer, James R. Ronca of Anapol Schwartz Weiss Cohan Feldman & Smalley, said he has settled 39 cases for a total of $19.9 million, which would work out to an average settlement of $510,000.
