title: Pharmacokinetics of Clivarin a new low molecular weight heparin in healthy volunteers.
abstract: The antithrombotic activity and pharmacokinetics of Clivarin, a low molecular weight heparin was randomly studied in 10 healthy male volunteers. Doses of 20, 40, 60 and 80 anti F Xa U/kg BW were injected intravenously and subcutaneously in crossover fashion. The heparin concentrations were measured by inhibition of clotting assays (anti IIa and anti Xa activities using amidolytic assays and [dilute] thrombin time). The pharmacokinetic profile of Clivarin is characterized by a linear relationship between dose and absorption, relatively low clearance and a long elimination half-life, and a high anti Xa/anti IIa ratio of 5.3.
