Daltroban (20 mg/kg per hour i.v.) reduces the ischaemia-induced rise in the ST segment and prevented the development of a Q-wave in the ECG during reperfusion, in comparison with vehicle (physiological saline)-treated cats. Daltroban (1 mg/kg; i.v.; per hour) exerts protective effect in reperfusion injury following acute myocardial ischemia in cats[2]. Daltroban protects the myocardium from ischaemic injury and that this effect involves prevention of ischaemia-induced leukocytosis[3].
