The Federal Trade Commission is investigating some of CVS Caremark Corp.'s business practices, the company said Thursday. The drugstore chain and pharmacy benefits manager did not disclose the details of the "nonpublic investigation," but said it has not violated any antitrust laws. CVS suggested the FTC inquiry is connected to complaints made by the Change to Win coalition of labor unions. Change to Win has said CVS Caremark's size and buying power is bad for consumers, and accused CVS of a stocking expired products and violating patients' privacy, among other issues.
