Crossover Study Comparing Ondansetron Orally Dissolving Film Strip (ODFS) With Zofran Orally Disintegrating Tablets

This was an open label, balanced, randomized, two-treatment, two-period, randomized sequence crossover study conducted in healthy adult male and female volunteers. Subjects checked into the study center on Day -1 of each study period at least 12 hours prior to dosing on Day 1. Subjects were served dinner between 8:00 pm to 8:30 pm to ensure minimum 10 hours fast prior to dosing in both periods. Subjects received the 2 treatments in a randomized order with a 7-day washout between the 2 periods.

Treatment A: single dose of ondansetron ODFS 8 mg was orally administered, allowed to dissolve, swallowed with saliva, followed with 240 mL room temperature drinking water

Treatment B: single dose of Zofran ODT (containing ondansetron 8 mg) was orally administered, allowed to dissolve, swallowed with saliva, followed with 240 mL room temperature drinking water
