In July 2008 Shire launched VYVANSE in 20mg, 40mg and 60mg dosage strengths, which are designed to increase the dosing flexibility of VYVANSE.
Product sales for the year to December 31, 2008 were $318.9 million (2007: $76.5 million). Product sales growth was driven by the increase in average share of the US ADHD market (8.2% for the year to December 31, 2008 compared to 1.8% in 2007) and a price increase in April 2008.
DAYTRANA - ADHD
Product sales for the year to December 31, 2008 were $78.7 million (2007: $64.2 million). DAYTRANA's average annual share of the US ADHD market decreased to 1.8% in 2008 compared to 2.1% in 2007.
Despite the 11% decrease in prescriptions compared to 2007, sales of DAYTRANA grew 23% compared to the same period last year due to growth in the US ADHD market of 7% and lower sales deductions in 2008 over 2007, primarily due to reduced coupon expense.
During 2008 Shire announced two voluntary market recalls of a limited portion of DAYTRANA patches because certain patches did not meet their release liner removal specifications which may have resulted in some patients and caregivers having difficulties removing the liners. The voluntary recalls were not due to safety issues. Shire and Noven Pharmaceuticals Inc. (the manufacturer of DAYTRANA) continue to pursue enhancements to the product and to work closely with the FDA to implement changes that may improve the usability of DAYTRANA. There has been no interruption in the production of DAYTRANA.
US oral mesalamine market share
Shire's average annual market share of the US oral mesalamine market rose to 28.4% for the year to December 31, 2008 (2007: 21.1%), driven by the growth of LIALDA since its launch in March 2007.
