The Caribbean island that produces 13 of the 20 best-selling drugs in the US has sold tainted pills and is struggling with quality control at its pharmaceutical plants, AP reports. FDA inspections of 13 Puerto Rican plants between 2003 and 2007 revealed problems such as machinery pins left in drug bottles and foreign material embedded in tablets.
Four of those plants have closed or plan to close, but none cited quality-control issues as the reason for shutting down. FDA officials largely attribute the problems to the island’s high number of pharmaceutical plants, saying the issue is generally no worse than an average US operation but because so many drugs are manufactured there, problems are magnified. Puerto Rico produces $35 billion of drugs every year and sells most of them in the US.
