The international product life cycle for the pharmaceuticals industry is one of the toughest and most unique.
In this industry, it is so difficult to get a product on the market with years of clinical trials and agency approval processes. An added catch on the international stage is that each country generally has to approve the product, making international growth difficult.
Those lucky enough to get past those hurdles are faced with extremely tough competition. Competitors are always looking to come up with the next miracle drug that may make yours obsolete.
