More Restructuring for Merck As Key Product Patents Expire

October 14, 2013

The planned restructuring, which also includes job cuts and a new home base address, is intended to adjust to declining sales in asthma and allergy drug Singulair (montelukast sodium) and other Merck products beset by generic competition.
