Last year, one of India’s biggest makers of generic drugs, Ranbaxy, paid a fine of $500 million to settle charges that it sold adulterated drugs and lied to the FDA. Later, the agency banned imports from a Ranbaxy factory where workers hid failures on quality tests by repeating them until they got acceptable results. In factories run by another drugmaker, Wockhardt, inspectors found urine spilling over open drains and mold growing in storage areas for raw materials. The FDA’s director, Margaret Hamburg, spent a week in India hammering home the message delivered by the factory bans. The FDA will expand its offices in India, train regulatory officials and strengthen inspections of overseas plants, she said. The push for improvement is funded by new fees collected from the generics industry that were approved by Congress in 2012. The FDA is also using $20 million of the money for the first widespread evaluation of the safety and quality of generics, whether made abroad or at home.
Generic drugs took off in the U.S. during the 1980s with the passage of the Hatch-Waxman Act, which made it easier and cheaper to bring a drug to market. In the 90s, generic production proliferated in India and China, where manufacturing can cost half as much as in Europe or the U.S. But regulation and oversight didn’t keep up. In the face of the rapid rise of generic-drug exports, regulators have adopted different approaches. The European Union mandates batch testing, where a sample from each shipment is tested before it can be released for sale; the FDA focuses on inspections and doesn’t do spot tests, although the FDA and the European Medicines Agency in December agreed to share information on inspections and safety studies. Some Indian manufacturers are considered to have stringent safety standards, but independent estimates of the extent of counterfeit medicines sold in the country range from 12 percent to 25 percent. Concerns with generics aren’t limited to India and China: in 2012, Teva Pharmaceuticals of Israel pulled one version of Wellbutrin after regulators said it wasn’t the same as the brand-name medicine.
At a Washington hearing in February, researchers reported finding signs of contamination in imported drugs and doctors spoke of their need to have patients try different versions of generics until they find one that performs as promised. While the FDA’s critics are pleased by its plans to add staff and step up overseas inspections, they think more needs to be done. In April, the chairman of a U.S.-Chinese safety commission, Dennis Shea, called the FDA “woefully, inadequately staffed” in China. Some experts would like doctors and patients to be given more information on where drugs come from. Hamburg said the key to safer generics is for overseas drugmakers to take responsibility for implementing the necessary quality-control procedures and local regulators to develop the expertise needed to enforce them. That may improve India’s U.S. exports but not benefit all patients. G.N. Singh, India’s top drug regulator, told India’s Business Standard in January that if he had to impose U.S. standards on factories making drugs for the Indian market, “we will have to shut almost all of those.”
