Prescription drug prices are the main force behind rising insurance premiums, for instance.Last month, the U.S. Senate and House passed legislation that allows Americans to buy foreign prescription drugs. Congress is deadlocked over the two versions. Last week, the AARP suggested that Congress limit those countries to Canada only.Then Wednesday, Pfizer, the world's largest drug company, announced that it would cut off supplies of Pfizer products — including Celebrex, Viagra and Lipitor — to 50 Canadian Internet pharmacies if those pharmacies don't stop reselling them to Americans at Canadian prices.Pfizer is trying to protect the safety of patients, a company press release said. Pfizer is "protecting the profits obtained by higher prices in the United States," AARP spokesman John Rother charged.Canadian wholesalers say Pfizer's action endangers people on both sides of the border. They note that Canadian patent law allows the government to authorize generic drug makers to manufacture generics if a shortage of a patented product develops."All this talk about safety of the patient," said White, who runs a clinic that sees thousands of uninsured people a month.
