There are concerns that the test may yield false negatives. To reduce the risk of false negatives. Ensure that testing is done in accordance with the authorized labeling. Providers should consider retesting patients by using a different test if an inaccurate result is suspected. Health professionals and patients are encouraged to report problems with test performance or results to the FDA’s MedWatch Safety Information and Adverse Event Reporting Program. Vinca Alkaloid Labeling for Preparation in Intravenous Infusion Bags Only 1/15/21 The FDA alerted health care professionals to labeling updates for the preparation of vinca alkaloids including vincristine sulfate injection, vinblastine sulfate for injection, and vinorelbine tartrate injection. To avoid unintended intrathecal administration, labeling is being updated to remove instructions for preparation of these products in a syringe and to recommend preparation in intravenous infusion bags only.

  • Meat Curing and Sodium Nitrite
    MEDIA MYTHCRUSHER Meat Curing and Sodium Nitrite The use of nitrite to produce cured meats like salami, ham, bacon and hot dogs, is a safe, regulated practice that has distinct public health benefits. However, much confusion and even mythology surrounds nitrite. Being mindful of key words and statistics and providing appropriate context can help reporters improve the accuracy of their coverage and the information that is passed on to readers and viewers. We’ve compiled ten tips to improve accuracy when writing about the use of sodium nitrite in cured meats. #1: Nitrite is not ‘unnatural’. Before the terms nitrate and nitrite are often used refrigeration was available, humans salted and interchangeably, meat companies mainly use dried meat to preserve it. It was discovered sodium nitrite to cure meat, not sodium nitrate. that the nitrate in saltpeter was extremely At the turn of the 20th century, German effective in causing a chemical reaction known scientists discovered nitrite (and not nitrate) as “curing.” Not only did this give meat a was the active form of these curing salts. When distinct taste and flavor, it also preserved it and added directly, rather than as nitrate, meat prevented the growth of Clostridium botulinum, processors can have better control of this which causes botulism. important curing ingredient and more closely manage how much they are adding. Later on, scientists came to understand that nitrate naturally found in the environment #3: Cured meats are a miniscule source of converts to nitrite when in the presence of total human nitrite intake. Scientists say that certain bacteria.

Nevertheless, under special conditions this transporter can also work in a reverse mode, in which direction of the ion transport is inverted—calcium ions are transported inside the cell and sodium ions are transported out of the cell. To date, three isoforms of the NCX have been identified and characterized in humans. Majority of information about the NCX function comes from isoform 1 (NCX1). Although knowledge about NCX function has evolved rapidly in recent years, little is known about these transport systems in cancer cells. This review aims to summarize current knowledge about NCX functions in individual types of cancer cells. Keywords: sodium-calcium exchanger; cancer cells; calcium; apoptosis 1. Background Intracellular calcium ions are considered the most abundant secondary messengers in human cells, since they have a substantial diversity of roles in fundamental cellular physiology. Accumulating evidence has demonstrated that intracellular calcium homeostasis is altered in cancer cells and that this alteration is involved in tumor initiation, angiogenesis, progression and metastasis.

Abstract: Aspartame is a sweetener introduced to replace the commonly used sucrose. It was discovered by James M. Schlatter in 1965. Being 180–200 times sweeter than sucrose, its intake was expected to reduce obesity rates in developing countries and help those struggling with diabetes. It is mainly used as a sweetener for soft drinks, confectionery, and medicines. Despite its widespread use, its safety remains controversial. This narrative review investigates the existing literature on the use of aspartame and its possible effects on the human body to refine current knowledge. Taking to account that aspartame is a widely used artificial sweetener, it seems appropriate to continue Citation: Czarnecka, K.; Pilarz, A.; research on safety.

  • (LC-HRMS) Method for the Determination of Six Nitrosamine Impurities in ARB Drugs
    05/21/2019 Liquid Chromatography-High Resolution Mass Spectrometry (LC-HRMS) Method for the Determination of Six Nitrosamine Impurities in ARB Drugs Background: Angiotensin II receptor blocker (ARB) drug products are commonly used to treat high blood pressure and heart failure. In July 2018, it was found that some ARB drug products contained carcinogenic nitrosamine impurities. As this incident continues to evolve, it has resulted in numerous recalls and ARB drug shortages in the US. As a member of the FDA’s working group to address this continually-evolving incident, CDER/OPQ/OTR is responsible for testing for nitrosamine impurities in ARB drug products and drug substances of interest. OTR has successfully developed and implemented GC/MS methods to quantitate N- nitrosodimethylamine (NDMA) and N-nitrosodiethylamine (NDEA) at trace levels. However, these GC/MS methods cannot yet directly detect N-nitroso-N-methyl-4-aminobutyric acid (NMBA), another nitrosamine impurity that was found in certain ARB drug products by some firms. In addition, it is speculated that three other nitrosamine impurities may also be present in ARB drugs from reviews of manufacturing processes and published literature sources, namely N-nitrosoethylisopropylamine (NEIPA), N-nitrosodiisopropylamine (NDIPA), and N- nitrosodibutylamine (NDBA). Thus, a single method was developed that was capable of detecting and quantifying all of the six aforementioned impurities simultaneously. Herein, we report an LC-HRMS method that has been validated for the simultaneous determination of the six nitrosamine impurities in losartan drug substance and drug product at sub-ppm levels. The method may also be capable of testing for these six impurities in other ARB drug substances and drug products pending verification and/or validation.

  • WHO Information Note UPDATE on NITROSAMINE IMPURITIES
    20, AVENUE APPIA – CH-1211 GENEVA 27 – SWITZERLAND – TEL CENTRAL +41 22 791 2111 – FAX CENTRAL +41 22 791 3111 – WWW.WHO.INT Ref. EMP/RHT/Information Note_Nitrosamine impurities April 2020 WHO Information Note UPDATE ON NITROSAMINE IMPURITIES Background Medicine Regulatory Authorities first became aware of the presence of the nitrosamine impurity, N• nitrosodimethylamine (NDMA), in products containing valsartan in July 2018. Valsartan is an Angiotensin II Receptor Blocker (ARB) and belongs to a family of analogue compounds commonly referred to as the sartans. Further nitrosamine impurities were subsequently detected in other medicines belonging to the sartan family, including: N-nitrosodiethylamine (NDEA), N -nitrosodiisopropylamine (NDIPA), N -nitroso- ethylisopropylamine (NEIPA) and N -nitroso-N-methyl-4-aminobutyric acid (NMBA). More recently, nitrosamine impurities have been reported in pioglitazone, ranitidine and metformin containing products.1-5 What are nitrosamines? Nitrosamines, or more correctly N-nitrosoamines, refer to any molecule containing the nitroso functional group. These molecules are of concern because nitrosamine impurities are probable human carcinogens. Although they are also present in some foods and drinking water supplies, their presence in medicines is nonetheless considered unacceptable. Figure 1: N• nitrosodimethylamine (NDMA) Figure 2: N-nitrosodiethylamine (NDEA) Why are they present? The formation of nitrosamines is generally only possible when secondary or tertiary amines react with nitrous acid. Nitrous acid itself is unstable but can be formed in situ from nitrites (NO2) under acid conditions. In the case of the sartan compounds, most contain a tetrazole ring and formation of this tetrazole ring employs the use of sodium nitrite. Coincidently the solvents employed either were amines, or contained traces of amines, and this likely afforded the observed NDMA and NDEA.

  • Retalac, Nitrosamines
    To whom it may concern Dr. Stefan Dreiheller Quality Unit / Regulatory Affairs Date of issue: 31.03.2021 Page 1/3 Doc.-No. EIP-5036 Revision 5 Nitrosamines EMA/369136/2020; FDA Guidance for Industry „Control of Nitrosamine Impurities in Human Drugs“ MEGGLE Product: RetaLac® The formation of potent genotoxic nitrosamines as impurities is possible in the presence of secondary, tertiary, or quaternary amines and nitrite salts under acidic reaction conditions. Regarding the requests of EMA-CHMP and FDA-CDER that marketing authorisation holders for human medicines containing chemically synthesised active substances have to evaluate the risk for the possible presence of nitrosamines (e.g. NDMA, NDEA, NMBA, NMPA, NIPEA, NDIPA), a risk evaluation was conducted for the MEGGLE product to support the marketing authorisation holders. This evaluation (page 2 and 3) is based on the IPEC Questionnaire. The product is a co-processed, directly compressible spray agglomerate comprising 50 % Lactose Monohydrate (Ph. Eur. / USP-NF / JP) and 50 % Hypromellose (Ph. Eur. / USP-NF / JP). The compound lactose monohydrate produced at MEGGLE is not chemically synthesized. Organic solvents, catalysts and other reagents which might be a reason for the presence of secondary, tertiary, or quaternary amines and nitrite salts are not used. Furthermore, acidic conditions as necessary prerequisite for the formation of nitrosamines are not achieved during manufacturing process. Lactose monohydrate is isolated and purified from whey which is a by-product of cheese manufacturing. Whey does not contain relevant amounts of nitrates (as precursor of nitrites) and nitrites. Testing on nitrates and nitrites is conducted as part of incoming goods inspection.

  • Lessons Learned
    Prevention and Reversal of Chronic Disease Copyright © 2019 RN Kostoff PREVENTION AND REVERSAL OF CHRONIC DISEASE: LESSONS LEARNED By Ronald N. Kostoff, Ph.D., School of Public Policy, Georgia Institute of Technology 13500 Tallyrand Way, Gainesville, VA, 20155 [email protected] KEYWORDS Chronic disease prevention; chronic disease reversal; chronic kidney disease; Alzheimer’s Disease; peripheral neuropathy; peripheral arterial disease; contributing factors; treatments; biomarkers; literature-based discovery; text mining ABSTRACT For a decade, our research group has been developing protocols to prevent and reverse chronic diseases. The present monograph outlines the lessons we have learned from both conducting the studies and identifying common patterns in the results. The main product of our studies is a five-step treatment protocol to reverse any chronic disease, based on the following systemic medical principle: at the present time, removal of cause is a necessary, but not necessarily sufficient, condition for restorative treatment to be effective. Implementation of the five-step treatment protocol is as follows: FIVE-STEP TREATMENT PROTOCOL TO REVERSE ANY CHRONIC DISEASE Step 1: Obtain a detailed medical and habit/exposure history from the patient. Step 2: Administer written and clinical performance and behavioral tests to assess the severity of symptoms and performance measures. Step 3: Administer laboratory tests (blood, urine, imaging, etc) Step 4: Eliminate ongoing contributing factors to the chronic disease Step 5: Implement treatments for the chronic disease This individually-tailored chronic disease treatment protocol can be implemented with the data available in the biomedical literature now. It is general and applicable to any chronic disease that has an associated substantial research literature (with the possible exceptions of individuals with strong genetic predispositions to the disease in question or who have suffered irreversible damage from the disease).
