New Delhi: Ranbaxy Laboratories has stopped production of its generic version of cholesterol lowering drug Lipitor until it investigates the issue of potential glass particles in certain lots, the US health regulator has said. The Indian drug major on November 9 had informed its customers of a voluntary recall of certain lots of the company`s 10mg, 20mg, and 40mg dosage strengths of atorvastatin tablets (generic version of Lipitor), the US Food and Drug Administration (USFDA) said in a statement. The lots of atorvastatin, packaged in bottles of 90 and 500 tablets, are being recalled due to possible contamination with very small glass particles similar to the size of a grain of sand (less than 1 mm in size), it added. "Due to this quality issue, Ranbaxy has decided to stop manufacturing atorvastatin until it has thoroughly investigated the cause of the glass particulates and remedied the problem," the statement said.
