In pharmacokinetics, a loading dose is an initial higher dose of a drug that may be given at the beginning of a course of treatment before dropping down to a lower maintenance dose. [ 1 ] A loading dose is most useful for drugs that are eliminated from the body relatively slowly, i.e. have a long systemic half-life .
The monitoring of warfarin and keeping the international normalized ratio (INR) between 2.0 and 3.0, along with avoiding over and under treatment, has driven a search for an alternative. [3] [14] A naturally occurring inhibitor of factor Xa was reported in 1971 by Spellman et al. from the dog hookworm. [15]
A new drug application (NDA) for the approval of apixaban was submitted to the US Food and Drug Administration (FDA) by Bristol-Myers Squibb (BMS) and Pfizer jointly after the conclusion of the ARISTOTLE clinical trial in 2011. [26] [12] Apixaban was approved for the prevention of stroke in people with atrial fibrillation in December 2012.
The p-methoxy group of apixaban connects to S1 pocket of FXa but does not appear to have any interaction with any residues in this region of FXa. The pyrazole N-2 nitrogen atom of apixaban interacts with Gln-192 and the carbonyl oxygen interacts with Gly-216. The phenyl lactam group of apixaban is positioned between Tyr-99 and Phe-174 and due ...
Here’s what to keep in mind about type 2 diabetes medications used to support weight loss and weight loss injections: Weight loss injections are safe and effective when used as prescribed .
Participants lost weight during the first 65 weeks of treatment and then maintained weight loss over the rest of the experiment. The four-year trial didn’t show any new safety concerns ...
As they are administered by injection (intravenous, intramuscular or subcutaneous), they are less suitable for long-term treatment. [ 1 ] Argatroban (as well as the hirudins) is used for heparin-induced thrombocytopenia , a relatively infrequent yet serious complication of heparin treatment that requires anticoagulation (as it increases both ...
However, long-term weight loss outcomes can be affected by a variety of factors. In a new study, researchers identified four of the most important factors for long-term weight loss in patients ...
