The US Food and Drug Administration (US FDA) has asked Torrent Pharmaceuticals Ltd to recall a batch of anti-psychotic drugs — Olanzapine tablets of 10 mg — citing defects in its packaging. The medicines are used to treat schizophrenia and bipolar disorders. This is the latest case of drug recall for an Indian company; in June, Sun Pharma was asked to withdraw some lots of Nimodine capsules from the US since the capsules were turning into crystals. Nimodine helps treat brain haemorrhage.
“This action is being taken as a precautionary measure due to the product being re-packaged in the US using a filler material that (removes or blocks) less moisture than what is approved in the application,” the FDA enforcement report said. The Ahmedabad-based pharmaceutical major had launched its generic olanzapine orally-disintegrating tablets in the US in 2011 after FDA approval. Referring to a particular lot (BS392004A, expiry 9/2014) of the drug, the report said that this was a firm initiated voluntary recall.
In June, the UK drugs regulator MHRA had asked Wockhardt to recall 16 medicines from pharmacies and wholesalers after it found deficiencies in manufacturing procedures at the company’s Waluj plant. Earlier, the FDA had also imposed an “import alert” on the same plant. In May, Glenmark Generics, a subsidiary of Glenmark Pharmaceuticals, had also made voluntary recall of multiple lots of three of its drugs from the US market due to “odd smell”, according to USFDA. Last November, the FDA asked Dr Reddy’s Laboratories to recall a batch of anti-psychotic drug quetiapine fumarate tablets of 25 mg, which failed dissolution test requirements.
Torrent’s Olanzapine is a generic version of Elli Lilly’s blockbuster drug Zyprexa, which had $3.2-billion US sales as on September 2011. The innovator drug went off-patent in October 2011. Analysts said the market size for the generic version for the drug was currently $360 million.
Torrent produced the specific batch of Olanzapine at its Indrad facility in Gujarat for US-based Prasco Laboratories, the enforcement report said. Torrent has a significant presence in the gastrointestinal, anti-infective, anti-diabetics and
