This study aims to determine the relative bioavailability of a FDC tablet formulation of 16mg candesartan cilexetil/12.5mg HCTZ relative to the reference product of same fixed dose combination (16mg candesartan cilexetil/12.5mg HCTZ) in healthy adult humans. This will be an open-label, randomised, single dose, two-way crossover study. Each subject will participate in two treatment periods and will be randomized to one of two sequences and administered one of the two treatments, A or B, as per the randomization schedule. The two treatment periods will be separated by a washout period of 7 to 14 days to ensure the candesartan and HCTZ have been effectively eliminated from the subject between dosing occasions. The study will enroll 16 healthy subjects to ensure that 14 subjects complete the study as planned.
