Ενώ ο FDA, έχει εδώ και 3 μήνες ανακαλέσει μεγάλη μερίδα από τις σαρτανες, ο Ευρωπαϊκός Οργανισμός Φαρμάκων, κινείται σε πιο αργούς ρυθμούς... Και ενώ, τα γεννοσημα από τις βαλσαρτανες ανακληθηκαν μετά από πολύ μεγάλη καθυστέρηση, και το καμπανάκι έχει χτυπήσει, το τοπίο παραμένει θολό..
Ο κόσμος το έχει τούμπανο, και εμείς κρυφό καμάρι....

UK pharmacists have been told to recall batches of blood pressuremedications found to contain cancer-causing contaminants, the medicines watchdog has said.
Directions affect thousands of
medicines containing the high blood pressure drug valsartan manufactured by two companies, Dexcel Pharma Ltd and Accord Healthcare.
They found traces of nitrate chemicals N-nitrosodimethylamine (NDMA), used in bacon and meat curing but known to be toxic to the liver and cancer-causing at higher doses, and N-Nitrosodiethylamine (NDEA), one of the carcinogens in tobacco smoke.
The latest recall affects four batches of Irbesartan medications, which pharmacists have been told to remove from sale, quarantine all remaining stock and return to suppliers.

Torrent expands its voluntary recall of losartan
Update [1/3/2019] Torrent Pharmaceuticals is expanding its voluntary recall to include eight additional lots of losartan potassium tablets, for a total of 10 lots. This recall is due to trace amounts of N-Nitrosodiethylamine (NDEA) in the losartan active pharmaceutical ingredient (API) manufactured by Hetero Labs Limited.
Torrent is only recalling lots of losartan medication containing NDEA above the interim acceptable intake level of 0.27 parts per million.
The agency also updated the list of losartan medications under recall.
FDA alerts patients and health care professionals to Aurobindo’s recall of valsartan medication due to NDEA
Update [1/2/2019] FDA is alerting patients and health care professionals to Aurobindo Pharma USA’s voluntary recall of two lots of valsartan tablets, 26 lots of amlodipine and valsartan combination tablets, and 52 lots of valsartan and hydrochlorothiazide (HCTZ) combination tablets due to the amount of N-Nitrosodiethylamine (NDEA) in the valsartan active pharmaceutical ingredient. Aurobindo is recalling amlodipine and HCTZ only in combination medications containing valsartan. Neither amlodipine nor HCTZ is currently under recall by itself.
Aurobindo is recalling lots of valsartan-containing medication that tested positive for NDEA above the interim acceptable daily intake level of 0.083 parts per million.
The agency continues to investigate and test all angiotensin II receptor blockers (ARBs) for the presence of NDEA and N-Nitrosodimethylamine (NDMA) and is taking swift action when it identifies these impurities that are above interim acceptable daily intake levels.
FDA also updated the list of valsartan products under recall and the list of valsartan products not under recall.
FDA reminds patients taking any recalled ARB to continue taking their current medicine until their pharmacist provides a replacement or their doctor prescribes a different medication that treats the same condition. Some ARBs contain no NDMA or NDEA.

FDA presents interim limits of nitrosamines in currently marketed ARBs
Update [12/19/2018] FDA is publishing interim acceptable intake levels of nitrosamine impurities in angiotensin II receptor blockers (ARBs) for manufacturers to use to ensure their finished drug products are safe for patients.
The agency evaluated safety data for N-Nitrosodimethylamine (NDMA) and N-Nitrosodiethylamine (NDEA) to determine an interim acceptable intake level for these impurities in the ARB class. NDMA and NDEA are probable human carcinogens and should not be present in drug products. We are currently aware of NDMA and NDEA in certain valsartan, irbesartan and losartan-containing products, and those products and some active pharmaceutical ingredients (API) used to manufacture them have been recalled from the U.S. market. See the list of valsartan products under recall and the list of irbesartan products under recall.

See the list of valsartan products under recall and the list of irbesartan products under recall.
Drug products that contain NDMA or NDEA above the limits in the table below pose an unacceptable risk to patients. The agency will use the interim limits to recommend manufacturers conduct a voluntary recall if laboratory testing confirms the presence of nitrosamine impurities in finished drug product. FDA is working with industry and international regulators to ensure products entering the market do not contain these impurities, but we are tolerating the impurities below the level established in the table for a short period of time to avoid a possible shortage of ARBs.
The agency reminds manufacturers they are responsible for developing and using suitable methods to detect impurities, including when they make changes to their manufacturing processes. If a manufacturer detects a new impurity or higher level of impurities, they should fully evaluate the impurities and take action to ensure the product is safe for patients. To aid industry and regulatory agencies, FDA has developed and published methods to detect NDMA and NDEA impurities – the gas chromatography/mass spectrometry (GC/MS) headspace method, the combined GC/MS headspace method, and the combined GC/MS direct injection method. These methods can be used for drug substances and products, and users should validate them as part of good manufacturing practices and where data are used to support a regulatory submission or required quality assessment of the API or drug product.
Not all ARB products contain NDMA or NDEA impurities, so pharmacists may be able to provide an alternative medication not affected by the recalls, or health care professionals may prescribe a different medication that treats the same condition.
* The acceptable intake is a daily exposure to a compound such as NDMA or NDEA that results in a 1:100,000 cancer
risk after 70 years exposure
** These values are based on a drug's maximum daily dose as reflected in the drug label

FDA updates NDMA and NDEA detection methods, announces posting of ZHP warning letter
Update [12/12/2018] The FDA has updated its testing methods to detect NDMA and NDEA impurities – the (GC/MS) headspace method, the combined headspace method, and the combined direct injection method – by adding the limits of detection (LOD) and clarifying that the methods can be used for both drug substances and drug products. These methods were validated with respect to valsartan drug substances and drug products, but the agency expects them to have comparable LODs and limits of quantitation (LOQ) for other angiotensin II receptor blockers (ARB).
The agency also issued a press release announcing the posting of a warning letter the agency issued Nov. 29 to Zhejiang Huahai Pharmaceuticals Co. Ltd. (ZHP).
