Dabigatran etexilate mesylate maximally prolongs the aPTT to 34.3 s, 44.0 s, and 63.0 s, respectively, 2h after 1, 2.5 or 5 mg/kg doses in the monkey. Animal Model: Male rats (280-350 g) and rhesus monkeys of either sex (3-8 kg) Dosage: 10, 20 and 50 mg/kg for rats and 1, 2.5 and 5 mg/kg for monkeys Administration: Oral Result: Had dose- and time-dependent anticoagulant effects.
