Among the carnage, there were a few bright spots, including two new drugs that may begin to make up for some of Lexapro's lost revenue. One, which I highlighted in December, is Linzess, an irritable bowel syndrome and constipation drug developed with Ironwood Pharmaceuticals. Sales of the drug, which only came to market in December, have totaled $19.2 million -- a great start in my book. Tudorza, Forest's inhaled COPD treatment, also launched in December, bringing in $12.2 million.
