title: A Canadian perspective.
abstract: Although the healthcare program in Canada is in many ways universal, there are several differences between the provinces. Two key federal bodies (the Health Protection Branch of Health Canada and the Patented Medicine Prices Review Board) are involved in the drug review process. In addition, the Canadian Coordinating Office for Health Technology Assessment (CCOHTA), an organization funded jointly by provinces and the federal government, reviews new or existing drugs at the request of provinces. Each province or territory and the federal government has its own drug plan or plans. The 10 Canadian provinces require a notice of compliance, information on pricing, and clinical and comparative information for submission of a new drug. Over the last 3 years, 8 of the 10 provinces have required pharmacoeconomic analyses to be added to the submissions. Four of the eight provinces requiring pharmacoeconomic evaluations have specified that these evaluations should be made according to the Canadian Coordinating Office for Health Technology Assessment guidelines. A review of the utilization patterns of lipid-lowering therapies is presented in this Canadian context. Statins comprised 80% of the lipid-lowering drug market in 1995. Prescribers use statins available in Canada interchangeably for all approved and nonapproved indications. The newest statin, atorvastatin, has attained a market share for new prescriptions equivalent to simvastatin and pravastatin, despite the lack of clinical outcome studies. CCOHTA reviewed the evidence of efficacy and effectiveness of statins, evaluated whether significant differences existed between statins, and analyzed published economic evaluations. It found that treatment of higher-risk patients with statins is more cost-effective than that of lower-risk subjects. The evaluation also concluded that the statins, as a class, probably act in reducing LDL and raising HDL, resulting in beneficial clinical outcomes.
