WALTHAM, Mass., Aug. 12 /PRNewswire/ -- Decision Resources, one of the world's leading research and advisory firms focusing on pharmaceutical and healthcare issues, finds that Merck/Schering-Plough's Zetia and Vytorin have lost substantial patient share in second- and third-line therapy since last year's analysis of the dyslipidemia drug market. This decline is most likely attributed to the publication of the ENHANCE trial which called into question the ability of these agents to improve clinical outcomes beyond the ability of statin monotherapy.
The new Treatment Algorithms in Dyslipidemia report also finds that statins have gained patient share with Zetia's and Vytorin's decline in use since the ENHANCE fallout. Survey results indicate that over the next two years cardiologists and primary care physicians intend to be more aggressive in their treatment of dyslipidemia. They also plan to increase their use of the most potent statins, particularly Pfizer's Lipitor and AstraZeneca's Crestor, and adjunct agents belonging to the classes of fenofibrates and bile acid sequestrants.
"Our survey of physicians indicates that favorable results from the 2008 JUPITER trial are likely to increase the percentage of physicians prescribing Crestor in the first line and may lead to increases in Crestor's patient share. However, Crestor will have to compete with the availability of generic Lipitor in 2011 and AstraZeneca should try to gain as much traction as possible prior to the arrival of this additional competition," stated Amanda Puffer, M.Sc., analyst at Decision Resources.
By combining patient-level claims data with physician survey data, this report can be used to build patient-flow models and analyze the assumptions driving these models.'/>"/>
