TABLE 2

Plasma PK of TSL in dogs after a p.o. dose of cardiotonic pills or an i.v. bolus dose of the injectable TSL solution For AUC0→t, the value of t is defined as the last quantifiable point; these were 2, 2, 4, or 4 h after the low, intermediate, high p.o. dose of cardiotonic pills, or the i.v. dose of the injectable TSL solution, respectively.
