The U.S. pharmaceutical industry continues to be the country’s most profitable business. Research shows that U.S. prescription medication prices are higher than any other developed country. One clinical trial can cost up to $100 million. The total price for developing and manufacturing some American drugs has reached $1 billion. Online Canadian pharmacies have become more popular as Americans searching for “Canadian pharmacy,” want convenient and affordable alternatives to buy name-brand prescriptions, generic and over-the-counter medications.

More than a million Americans use International Pharmacies to fill essential prescriptions every year. Because of Canada’s proximity to the United States, it’s a popular choice.
