Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Heparin binds to antithrombin III, accelerating the inactivation of thrombin (factor IIa) and factor Xa, thereby inhibiting coagulation.
MIRADON (anagrelide) inhibits cyclic nucleotide phosphodiesterase and the release of arachidonic acid from phospholipids, possibly by inhibiting phospholipase A2. It also suppresses megakaryocyte maturation and platelet production.
For therapeutic anticoagulation, administer intravenous bolus of 80 units/kg followed by continuous infusion at 18 units/kg/hour, adjusted to maintain aPTT 1.5-2.5 times control. For prophylaxis, 5,000 units subcutaneously every 8-12 hours.

Mean terminal half-life 1.5 hours (range 1-2 hours) at therapeutic doses; dose-dependent (nonlinear) due to saturable clearance; prolonged in renal impairment (up to 3-6 hours) and hepatic disease.
Terminal elimination half-life is 8-12 hours in adults with normal renal function. In patients with creatinine clearance <30 mL/min, half-life may extend to 20-30 hours. The half-life supports twice-daily dosing in most patients.
Primarily hepatic and reticuloendothelial system metabolism; renal excretion of metabolites accounts for <50% of clearance; minimal biliary/fecal elimination.
Renal excretion of unchanged drug accounts for 60-70% of the administered dose. Fecal/biliary excretion accounts for 20-25%, with the remainder as oxidative metabolites. Up to 10% is eliminated as glucuronide conjugates.
