Cross-over study to prove bioequivalence between two oral formulations of levonorgestrel 1.5 mg

Trial purpose

A single dose, two treatments (Postinor-2 and Opxion), two periods, two sequences, crossover, randomized, prospective design was chosen with a washout of 14 days between the two study periods. Treatment groups are balanced with the same number of male healthy volunteers who were randomly assigned to the study drug administration sequences.
