In January, US FDA revoked the ban imposed on Lupin’s manufacturing facility at Mandideep in Madhya Pradesh.
The US FDA had conducted an inspection at Lupin’s manufacturing facility at Mandideep, in October – November 2008.
The US FDA inspection found several deficiencies in the Good Manufacturing Standards (GMP) standards set by the agency and issued Inspectional Observations also known as Form 483 listing all the deviations.
Lupin’s Mandideep facility makes both sterile and non-sterile pharmaceutical manufacturing and sterile active pharmaceutical manufacturing factories.
US FDA has cited Lupin’s failure to maintain production, control, or distribution records and failure to follow appropriate written procedures designed to prevent microbiological contamination of drug products to be sterile.
Lupin’s Mandideep facility also found to be lacking in controls to prevent contamination in defined areas regarding operations related to aseptic processing of products. The plant managers also failed to routinely calibrate, inspect, or check according to a written programme designed to assure proper performance of automatic, mechanical, or electronic systems.
