The medications include Johnson & Johnson's Procrit, and Amgen's Epogen and Aranesp.
The clinical trial from 2004 involved diabetic and kidney disease patients
taking Aranesp. Those who took the drug were no more likely to die than those on a placebo, but had about double the rates of stroke.
Anemia drugs are used for patients with conditions such as chronic kidney disease and people undergoing chemotherapy, etc.
