Brief Summary:
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.

  2. Area under the pharmacokinetic curve from time=0 to last blood sample [ Time Frame: After 2 months ]
  3. Half life of plasmatic concentration of study drug [ Time Frame: After 2 months ]
  4. Clearance constant of plasmatic concentration of study drug [ Time Frame: After 2 months ]
  5. Adverse events collection [ Time Frame: Up to 8 weeks ]
