hour delay in onset of drug action after subcutaneous administration. Intramuscular injection of heparin is to be avoided because of unpredictable absorption rates, local bleeding, and irritation. Heparin is not bound to plasma proteins or secreted into breast milk, and it does not cross the ...

Adjust the dosage of heparin sodium according to the patient’s coagulation test results. When heparin is given by continuous intravenous infusion, determine the coagulation time approximately every 4 hours in the early stages of treatment. When the drug is administered intermittently by intrav...
Digitalis, tetracyclines, nicotine, antihistamines, or intravenous nitroglycerin may partially counteract the anticoagulant action of heparin sodium. Heparin Sodium In 5% Dextrose Injection Intravenous nitroglycerin administered to heparinized patients may result in a decrease of the partial thromboplastin time ...
It is now knownthat the active center serine of thrombin and other coagulation enzymesare inhibited by an arginine-reactive site on the AT Mechanism of Action Only about one third of an administered dose of heparin binds toAT, and this fraction is responsible for most of its anticoagulanteffect...
There is an approximate 2-hour delay in onset of drug action after subcutaneous administration. Intramuscular injection of heparin is to be avoided because of unpredictable absorption rates, local bleeding, and irritation. Heparin is not bound to plasma proteins or secreted into breast milk, and it...
maintaining the biological activity of heparin is essential. A hydrophilic spacer chain between the PU surface and the heparin molecules improves its biological action. As heparin is an anionic polysaccharide, it can be immobilized on a cationic surface via ionic bonding[30]. In addition, covalent ...

37The most promising agent isargatroban, a synthetic direct thrombin inhibitor that has a rapid onset of action, a half-life ranging from 39 to 51 minutes, and hepatic metabolism. Argatroban therefore requires no dose adjustment in dialysis patients and only a 20% systemic clearance is seen ...
