Twenty-four women participated in this randomized controlled, crossover study comparing the bioavailability and pharmacokinetics of a vaginal progesterone capsule (200 mg/dose) vs a progesterone vaginal gel (90 mg/dose). Both were well tolerated, and no differences were noted with respect to safety. The vaginal capsule delivered more progesterone, however peak concentrations between the two preparations didn’t differ.
