Later, the same will be inserted in randomization table, which was outlined in a randomized crossover for two drugs, the randomization scheme will be in the balanced cross 2 x 2. A design is said to be balanced if it satisfies the following conditions:

· Each medication is applied only once in each subject;

• in each period, the number of subjects receiving each medicine must be equal; This randomization was previously performed by the computer program and by a qualified professional Prof. Dr. Yuko Wada Cilicia (PhD in Biostatistics and PhD of Biostatistics, UNICAMP) of Statpharm Scientific Consulting Ltda.

All study medication will be labeled according to the randomization, previously performed by pharmacy LAL Clinica, which should make conference material for 3 checks.
