Public Citizen issued a statement on Tuesday calling the FDA "unconscionable" for denying a petition to ban Aricept 23, an Alzheimer's drug from manufacturer Eisai. According to Sidney Wolfe, the director of Public Citizen's Health Research Group, studies have failed to show the drug to be more effective than lower-dose drugs, but the drug did cause more vomiting, which can lead to pneumonia, gastrointestinal bleeding, esophageal rupture or death. Wolfe questioned whether the agency was "protecting the public health or, in effect, colluding with the drug industry when it denied a petition to ban Aricept 23, deciding to leave the dangerous drug on the market."
