The pharma major, part of US-based Abbott, has also asked the state drug regulatory authority to provide more information about the source of the suspect sample and the manner in which it was collected.
"Abbott has requested the State Drug Controller to provide more information about the source of the suspect sample and the manner in which it was collected, to establish whether the sample was collected from genuine trade channels through proper process under the Drugs and Cosmetics Act," a Abbott India spokesperson told PTI.
The batch of Phensedyl, from which the state government authorities picked up the sample, was manufactured by the company in February 2014 and distributed in March 2014.
As soon as Abbott received information about the suspect sample, the company tested a retained sample both in-house using its own method of analysis, as well as by an accredited independent laboratory.
