A loading dose is most useful for drugs that are eliminated from the body relatively slowly, i.e. have a long systemic half-life. Such drugs need only a low maintenance dose in order to keep the amount of the drug in the body at the appropriate therapeutic level, but this also means that, without an initial higher dose, it would take a long ...
[28] [29] In August 2014, the FDA approved apixaban for the additional indication of the treatment of recurring deep vein thrombosis and pulmonary embolism. [28] [30] During its development the drug was known as BMS-562247-01. [31] By late 2019, sales of the product by BMS accounted for thirty percent of their quarterly revenue. [32]
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]
Average molecular weight: heparin is about 15 kDa, and LMWH is about 4.5 kDa. [25] Less frequent subcutaneous dosing than for heparin for postoperative prophylaxis of venous thromboembolism. Once or twice daily subcutaneous injection for treatment of venous thromboembolism and in unstable angina instead of intravenous infusion of high-dose heparin.
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. ...

Think about the healthy life years you gain just from minimizing these risks, considering lung cancer and heart disease are by far the leading causes of premature deaths among men and women in the US.
Continuing the maintenance dose for about 4 to 5 half-lives (t 1/2) of the drug will approximate the steady state level. [1] One or more doses higher than the maintenance dose can be given together at the beginning of therapy with a loading dose. [2] A loading dose is most useful for drugs that are eliminated from the body relatively slowly ...
