Enoxaparin at 0.8 mg/kg every 6 h is used in dogs to prevent prothrombotic events, but has only been validated in healthy Greyhounds, a breed with documented hypocoagulable haemostatic profiles in vitro and bleeding tendencies in vivo. This study investigated the effects of enoxaparin at this dose rate on the coagulation parameters of eight healthy adult Beagles over a 48 h period. Anti-Xa activity was significantly increased 3 h after the second and third of nine injections, and target anti-Xa activity was only reached transiently in 3/8 dogs. Paradoxically, a transient increase in endogenous thrombin potential was observed 6 h after the third injection. Other haematologic, biochemical and coagulation parameters were not significantly altered from the baseline values during enoxaparin treatment ( P > 0.05). This study suggests that assumptions regarding the pharmacodynamic effects of enoxaparin are not generalisable across breeds. [ABSTRACT FROM AUTHOR]
