Description	Dabigatran Etexilate is the prodrug of dabigatran, a potent, nonpeptidic small molecule that specifically and reversibly inhibits both free and clot-bound thrombin by binding to the active site of the thrombin molecule.
In vitro	Dabigatran selectively and reversibly inhibits human thrombin (Ki: 4.5 nM) as well as thrombin-induced platelet aggregation (IC50: 10 nM), while showing no inhibitory effect on other platelet-stimulating agents. Dabigatran selectively and reversibly inhibits human thrombin (Ki: 4.5 nM) as well as thrombin-induced platelet aggregation (IC50: 10 nM), while showing no inhibitory effect on other platelet-stimulating agents. Dabigatran inhibits thrombin generation in platelet-poor plasma (PPP) with IC50 of 0.56 μM, measured as the endogenous thrombin potential (ETP). Dabigatran demonstrates concentrationdependent anticoagulant effects in various species in vitro, doubling the activated partial thromboplastin time (aPTT), prothrombin time (PT) and ecarin clotting time (ECT) in human PPP at concentrations of 0.23, 0.83 and 0.18 μM, respectively. [1]
In vivo	Dabigatran prolongs the aPTT dose-dependently after intravenous administration in rats (0.3, 1 and 3 mg/kg) and rhesus monkeys (0.15, 0.3 and 0.6 mg/kg). [1] Dabigatran etexilate (20 mg/kg, orally) produces less prolongation of K value and less decreases in angle and maximum amplitude than enoxaparin in swine. [2] Dabigatran (0.01-0.1 mg/kg) reduces thrombus formation dose-dependently, with an ED50 (50% of the effective dose) of 0.033 mg/kg and complete inhibition at 0.1 mg/kg. Dabigatran etexilate (5-30 mg/kg) inhibits thrombus formation in a dose- and time-dependent manner, with maximum inhibition within 30 min of pretreatment, suggesting a rapid onset of action.[3]

Por exemplo, para modificar a dose de resveratrol usada para um camundongo (22,4 mg / kg) para uma dose baseada na BSA para um rato, multiplique 22,4 mg / kg pelo fator Km para um camundongo e, em seguida, divida pelo fator Km para um rato. Este cálculo resulta em uma dose equivalente de rato para o resveratrol de 11,2 mg / kg.

Rat dose (mg/kg) = mouse dose (22.4 mg/kg) ×	mouse Km(3)	= 11.2 mg/kg
