In short, the majority of the brand name drugs that you would be used to seeing at your corner pharmacy are sold in most nations of the world. For different markets, due to language and cultural differences they may have a different name or a different colored box or even a different presentation (e.g. in Canada, the U.S. drug “Prilosec” is called “Losec” and is a pill rather than a capsule, even though it is the same drug made by the same manufacturer). In almost all cases though however, the chemical name is exactly the same which means it is the same drug. There are a few instances where a chemical is called a different name in a different market (e.g. one of the chemicals in an asthma inhaler named “Combivent” is called “albuterol” in North America but “salbutamol” in the rest of the world). These differences though are rare. Most brand name drugs, although called different names in different markets, are even manufactured in the exact same plants but just packaged differently.
