Following a seven day wash out period, subjects returned and were dosed with an alternative treatment as per randomization

Thirty-six (N=36) volunteers were enrolled in the study. Subject 07 elected to withdraw foe personal reasons prior to period II check in. Subject 22 was excluded from statistical analysis due to emesis before twice the median Tmax of reference product
