Dr Reddy's Laboratories has submitted a response to the US health regulator on a warning letter it had received last month.
"We would like to inform that the company has submitted a response to the US Food and Drug Administration (USFDA) on December 7", Dr Reddy's Laboratories said in a filing to the BSE.
Last month, the country's second-largest drug maker had received a warning letter from the USFDA relating to two of its API manufacturing plants and a formulation plant in Andhra Pradesh and Telangana.
In response to the letter, DRL CEO G V Prasad had said the company is in the process of shifting some of the products from these plants to other facilities and considering third party assessment for its plants.
The US agency had asked the drug maker to provide a comprehensive evaluation of the extent of inaccuracies in recorded and reported data and include a detailed action plan to fully investigate the scale and root causes of "deficient documentation and data management practices".
Shares of Dr Reddy's Laboratories today ended at Rs 3,070.85 apiece on the BSE, down 3.44 per cent from previous close.
