Abstract

Effect of ε-aminocaproic acid on fibrinolysis in plasma of Asian elephants (Elephas maximus).

Abstract

ε-Aminocaproic acid (EACA) is a lysine analogue antifibrinolytic drug used to treat bleeding disorders in humans and domestic animals. Use in zoological medicine is rare and dose recommendations are anecdotal, but EACA may be a valuable therapeutic option for bleeding disorders in exotic species, including Asian elephants (Elephas maximus). This study used an in vitro model of hyperfibrinolysis and a thromboelastograph-based assay to estimate the therapeutic plasma concentration of EACA in Asian elephants (61.5 µg/ml, 95% CI=34.6-88.5 µg/ml). Substantial but incomplete inhibition of lysis was seen at relatively low concentrations of EACA (40 µg/ml). Asian elephants appear sensitive to EACA-mediated inhibition of hyperfibrinolysis. Doses published for domestic animals, targeting higher plasma concentrations, may be inappropriate in this species.
