This is a randomized, single-blind, two-period crossover study in which each subject will receive both treatments and therefore act as their own control to minimize confounding covariates within the study population. Randomizing subjects to treatment sequence will assist with reducing the potential order effects that might confound the findings if all the subjects received the same treatment sequence.
