Antistasin, the first discovered naturally occurring direct Xa inhibitor Rivaroxaban, the first synthetic direct Xa inhibitor marketed as a drug Prior to the introduction of direct factor Xa inhibitors, vitamin K antagonists such as warfarin were the only oral anticoagulants for over 60 years, and together with heparin have been the main blood ...
Rivaroxaban bears a striking structural similarity to the antibiotic linezolid: both drugs share the same oxazolidinone-derived core structure. [38] Accordingly, rivaroxaban was studied for any possible antimicrobial effects and for the possibility of mitochondrial toxicity, which is a known complication of long-term linezolid use. [39]
Andexanet alfa, sold under the brand name Andexxa among others, is an antidote for the medications rivaroxaban and apixaban, when reversal of anticoagulation is needed due to uncontrolled bleeding. [8] It has not been found to be useful for other factor Xa inhibitors. [9] It is given by injection into a vein. [9]
Heparin targets multiple factors in the blood coagulation cascade, one of them being FXa. At first, it had many side effects but for the next twenty years, investigators worked on heparin to make it better and safer. It entered clinical trials in 1935 and the first drug was launched in 1936. Chains of natural heparin can vary from 5.000 to 40. ...
In menaquinone the side chain is composed of a varying number of isoprenoid residues. Vitamin K antagonists (VKA) are a group of substances that reduce blood clotting by reducing the action of vitamin K. The term "vitamin K antagonist" is technically a misnomer, as the drugs do not directly antagonize the action of vitamin K in the ...
While a low-fiber diet is generally used for acute diverticulitis, the NIH guidelines recommend a high-fiber diet for patients with diverticulosis (a condition that may lead to diverticulitis). [17] A Mayo Clinic review from 2011 showed that a high-fiber diet can prevent diverticular disease.
[4] [9] Adverse effects may be class-dependent, and so switching to a biologic of another class may ameliorate those effects. [ 7 ] Potential serious adverse effects include allergic reactions , liver damage, cancer, and serious infections including tuberculosis , pneumonia , staph infection , and fungal infection .
The Lectin-free diet (also known as the Plant Paradox diet) is a fad diet promoted with the false claim that avoiding all foods that contain high amounts of lectins will prevent and cure disease. [1] There is no clinical evidence the lectin-free diet is effective to treat any disease and its claims have been criticized as pseudoscientific .
