Alabama resident Audrey Singleton was awarded $9.45 million yesterday by a Philadelphia jury in a lawsuit against drug maker Pfizer, Inc., after she claimed that the company’s hormone-replacement drug gave her breast cancer. Singleton began taking the drug Prempro in 1997 and was diagnosed with breast cancer in 2004. A 2002 study linked the drug to cancer. Pfizer has lost seven of 10 similar cases that have gone to jury.
