Pennsylvania Employees Benefit Trust Fund, which administers health-care benefits to state employees and retirees, is accusing Merck & Co. and Schering-Plough Corp. of misleading consumers about cholesterol pills Zetia and Vytorin. The suit, filed Friday in federal court in Philadelphia, seeks to recoup more than $9 million spent on the two drugs since October 2002 on the grounds that an older, less expensive medication, simvastatin, was just as effective.
