U.S. regulators have expressed doubts about the safety and efficacy of Indian medicines. They presume, that Indians drugmakers forge the test results and sell counterfeit drugs. U.S. authorities have imposed a ban on imports of several drugs that were posed for the antibiotic Cipro, Neurontin and analgesic remedy against acne Accutane, reports The Almagest.

Dr. Margaret Hamburg from the Office of the U.S. Food and Drug Administration (FDA) recently visited India and came to the conclusion, that there are great lapses in the quality of the medicines by few pharmaceutical firms.

In total more than 100 Indian drug companies have been inspected. The increased enforcement of FDA has cost several Indian companies too much. For example, Ranbaxy, the biggest drug manufacturer in the country, suffered the biggest losses. Last year it already had problems and paid a $500 mln fine.

The drug industry of India is an important sector boosting up the economy of the country. It exports $15 billion in products annually. However, in a new data by World Health Organization it is revealed 20 percent of drugs manufactured in the country are fakes.
