Two United States senators have asked the US Food and Drug Administration (USFDA) to provide details of market approvals given to all medicines sold by India's largest drug-maker Ranbaxy in that country.

The senators, John Dingell and Bart Stupak, also want the FDA inspectors who were in charge of drug approvals for Ranbaxy to appear before a House of Representatives committee by the end of August.
