Conditions
Brief summary
3 different formulations and doses of tafamidis will be compared. Subjects will be fasted for each test and every subject will test all 3 different formulations. After swallowing tafamidis, tafamidis blood concentrations will be measured periodically for 8 days. After 14 days, subjects will take a different formulation of tafamidis and tafamidis blood concentrations will be measured periodically for 8 days. After another 14 days, the last formulation will be tested in the same way.
