DEERFIELD, Ill., Oct. 1, 2012 /PRNewswire/ -- Horizon Pharma, Inc. (NASDAQ: HZNP) announced today that it has completed the expansion of its sales force from 80 to 150 representatives. This expansion will allow increased reach and frequency of calls on physician targets for its lead product DUEXIS ® (ibuprofen and famotidine), which is indicated for the relief of signs and symptoms of rheumatoid arthritis and osteoarthritis and to decrease the risk of developing upper gastrointestinal ulcers. In addition, the Company will leverage its expanded sales force to launch its recently approved product, RAYOS (prednisone) delayed-release tablets, which will be available to physicians this quarter. In June, Horizon entered an agreement granting Mallinckrodt, the Pharmaceuticals business of Covidien, the right to co-promote DUEXIS in the United States through December 31, 2014, which also added an undisclosed number of sales representatives. "Our sales force expansion, in addition to the Mallinckrodt sales representatives who began promoting DUEXIS in late August, will allow us to broaden our reach for DUEXIS five-fold from 10,000 physicians who write 8 percent of NSAID prescriptions to 50,000 physicians who write more than 50 percent of NSAID prescriptions," said Timothy P. Walbert, chairman, president and chief executive officer of Horizon Pharma. "Early prescription growth as a result of this increased promotion beginning in late August has shown a positive initial trend with total August DUEXIS prescriptions growing 16 percent. With our recent $81 million public offering and our combined promotional effort in full force, we believe DUEXIS is well-positioned for future growth.
