Does the FDA have a problem with endotoxins?
Main results: Bacterial endotoxin is a potent and predominant microbial mediator that induces an intense inflammatory and procoagulant response by elements of the innate immune response. This macromolecule is capable of inducing lethal septic shock in experimental animals, and a …
Do microbiological levels affect endotoxin levels?
This determined value means that if a parenteral drug manufacturer is using the LAL method for endotoxin testing of Cyanocobalamin Inj., the product can have no more than 350 EU/ml of product. LAL ...
What are the treatment options for endotoxins in dialyzers?
Endotoxins are a highly pyrogenic and immunogenic contaminant of bacterial origin that must be avoided during the manufacturing of biopharmaceutical products to ensure safety and efficacy. Low endotoxin recovery, also known as a masking effect, is defined as the ability to detect …
Why is the endotoxin limit expressed as K/M?
Endotoxins are pyrogens that can cause fever and illness in the human body. An endotoxin limit is the amount of endotoxin activity that can be safely contained in a product. These limits are …
What is the FDA approved method for endotoxin testing?
There are four basic methods commercially available and currently approved by FDA for end-product release testing: (i) the gel-clot; (ii) the turbidimetric (spectrophotometric); ( iii) the colorimetric (Lowry protein); and (iv) the chromogenic assay. The LAL reagents used in these methods must be obtained from an FDA-licensed manufacturer and must be designed specifically for the method chosen. Many of the other LAL methods appearing in the literature are modifications of the gel-clot or turbidimetric test and some have been designed to use less LAL than the basic method.
What is the endotoxin limit?
Because the dose varies from product to product, the endotoxin limit is expressed as K/M. K is 5.0 EU/kilogram (kg.), which represents the approximate threshold pyrogen dose for humans and rabbits.
What is the endotoxin in gram negative bacteria?
Bacterial endotoxins, found in the outer membrane of gram-negative bacteria are members of a class of phospholipids called lipopolysaccharides (LPS). LPS are not exogenous products of gram negative bacteria. The release of LPS from bacteria takes place after death and lysis of the cell.
Is it better to remove endotoxins from finished products?
It is difficult to remove endotoxins from products once present. It is far better to keep finished products and components relatively endotoxin-free rather than have to remove it once present.
What is a pyrogen?
"Microbial pyrogen" as opposed to "gram negative bacterial endotoxin" has become a general descriptive term for many different substances. However, pyrogenic substances can be produced by some gram positive bacteria, mycobacteria, fungi and also viruses, but the pyrogens produced by gram negative bacteria, i.e., the endotoxins, are of significance to the pharmaceutical industry.

What drug did Anna Wilson use?
When Anna Wilson* was hospitalized with blood clots in her lungs at age 16, she was put on a morphine drip and then discharged with a prescription for Vicodin.

How long does it take to get a buprenorphine waiver?
In order to prescribe buprenorphine, the Drug Enforcement Agency (DEA) requires doctors to apply for a waiver, which entails an eight-hour training course. So the ED launched a three-month “Get Waivered” campaign for its physicians, complete with a website, and worked with the DEA to streamline the training.
Who is Eric Weintraub?
Eric Weintraub, MD, medical director of Psychiatric Emergency Services at the University of Maryland Medical Center, was an early adopter of initiating addiction treatment in the ED. More than a decade ago, he noticed that most of the mental health issues he saw in the ED were related to substance use. “Patients had trouble getting the appropriate treatment,” he says. “I thought if we could take care of that then their mental health problems would get better.”
Who is Ross Sullivan?
Ross Sullivan, MD, assistant professor of emergency medicine at the State University of New York Upstate Medical University in Syracuse, used to refer overdose victims he saw in the ED to local addiction treatment centers. But when he learned that they often faced long wait times, risking the chance of relapse, he took matters into his own hands.
