5mg Apixaban
After a 10 hour fast, participants were randomized to one of six treatment sequences (ABC, ACB, BAC, BCA, CAB or CBA) administered over 3 periods. Fasted participants received a single dose of apixaban 5 mg on Day 1 of Periods 1, 2, and 3. Treatment A was administered via oral syringe, Treatment B was administered via an NGT followed by 60 mL of D5W via an NGT, and Treatment C was administered via an NGT, followed by 60 mL of infant formula via an NGT. There was at least a 4 day washout before receiving the next scheduled treatment in the next period.
