This is a table of volume of distribution (V d) for various medication. For comparison, those with a V d L/kg body weight of less than 0.2 are mainly distributed in blood plasma, 0.2-0.7 mostly in the extracellular fluid and those with more than 0.7 are distributed throughout total body water.
In pharmacology, the international unit (IU) is a unit of measurement for the effect or biological activity of a substance, for the purpose of easier comparison across similar forms of substances. International units are used to quantify vitamins and biologics ( hormones , some medications , vaccines , blood products and similar biologically ...
One unit of heparin (the "Howell unit") is an amount approximately equivalent to 0.002 mg of pure heparin, which is the quantity required to keep 1 ml of cat's blood fluid for 24 hours at 0 °C. [ 63 ]
While some studies have found that vitamin D 3 raises 25(OH)D blood levels faster and remains active in the body longer, [44] [45] others contend that vitamin D 2 sources are equally bioavailable and effective for raising and sustaining 25(OH)D. [46] [47] If digestive disorders compromise absorption, then intramuscular injection of up to ...
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.
There is no internationally accepted molecular standard for the composition of heparin, as it is a complex polymer of GAG units and uronic acids (including D-glucuronic acid, L-iduronic acid, and D-glucosamine). Position of N-acetyl, N-sulfate, and O-sulfate groups in these uronic acids can vary, as can the branching patterns of the chain.
Taurolidine/heparin, sold under the brand name Defencath, is a fixed-dose combination catheter lock solution used for central venous catheter instillation. [ 1 ] [ 2 ] It contains taurolidine , a thiadiazinane antimicrobial; and heparin , an anti-coagulant .
Protamine sulfate is a medication that is used to reverse the effects of heparin. [3] It is specifically used in heparin overdose, in low molecular weight heparin overdose, and to reverse the effects of heparin during delivery and heart surgery. [3] [4] It is given by injection into a vein. [3] The onset of effects is typically within five ...
