Brand name drugs are subject to review by the Canadian Patent Review Board so that prices are not excessive. They use what is called reference pricing to find a fair price. Specifically, the Board chooses the median price of the following list of countries: France, Germany, Italy, Sweden, Switzerland, the United Kingdom and the USA.
Thats the reason the same drugs sold here are much cheaper in Canada. Generic drugs are not regulated this way in Canada, which is one of the reasons generics are often lower in the U.S.
Canadas prices for brand drugs are almost always lower than in the U.S. However, its common for other countries to have even lower prices than in Canada, because their laws keep prices even lower. As you can see in our press release(https://www.pharmacychecker.com/news/70-percent-of-brand-name-drugs-are-imported-cost-87-percent-less-in-canada.asp) , you can often find popular brand name drugs for up to 87% less in Canada and for as much as 97% less in other countries.
