Last year, U.S. Customs and Border Protection seized $5.6 million worth of illegal pharmaceutical products, a 170% increase over 2005. Meanwhile, global sales of counterfeit medicines were estimated to be more than $75 billion last year, 90% more than in 2005. In response, Pfizer and the National Association of Boards of Pharmacy announced Thursday the launch of an effort to educate patients on how to safely buy medicines online and about the risks of counterfeit drugs.
