Rosuvastatin is used for the management of primary hypercholesterolaemia, mixed dyslipidaemia and familial hypercholesterolaemia. According to IMS Health, Crestor had Canadian sales of approximately CA$742 million during 2011.

Mr Dick Guest, President of Mylan Canada said that the generics manufacturer was ‘very pleased to introduce Mylan-Rosuvastatin to the Canadian market,’ adding that ‘not only does this introduction provide Canadians with access to our quality medicine, it does so at a substantially lower cost.’ According to the Canadian Heart and Stroke Foundation, about 40% of Canadians have high blood cholesterol, equating to about 10 million Canadian citizens [1].

In Canada, generic drugs cost consumers an average of 60% less than their brand-name counterparts.

Due to an absence of patent extensions for Crestor in Canada, the patent protecting the molecule will expire in July 2012. In the US the patent has been extended by three and a half years and will expire in 2016. In Germany and UK, the 5-year extensions on the rosuvastatin active ingredient patent will expire in June 2017.

Although good news for Mylan, there may not be so much room for generic rosuvastatin to take a chunk of the massive statin pie, due to generic atorvastatins already on the market. A clinical trial carried out by AstraZeneca indicated that Crestor (rosuvastatin) showed no statistically significant benefit over Pfizer’s Lipitor (atorvastatin), for which generics have existed since patents expired in November 2011 [2].
