Study of Treatment With the Combination of Drospirenone Plus Ethinyl Estradiol Plus Levomefolate Calcium in Mexican Women Seeking Contraception
Study of Treatment With the Combination of Drospirenone Plus Ethinyl Estradiol Plus Levomefolate Calcium in Mexican Women Seeking Contraception
The objective of this study is to compare the red blood cell (RBC) and plasma concentrations
 of folate in subjects treated with drospirenone (DRSP)/ethinyl estradiol (EE) plus
 levomefolate calcium (L-5-MTHF) at 24 weeks with respect to basal determination.

 Increased intake of folic acid (synthetic form of the naturally occurring B-vitamin) before
 and in the first few weeks of pregnancy has been shown to reduce certain types of birth
 defects. This is important for women who may become pregnant following discontinuation of
 oral contraception. Information about any side effects that may occur will also be collected.
Inclusion Criteria:

 -  Healthy, Mexican female subjects requesting contraception

 time of informed consent

 -  Normal or clinically insignificant cervical smear not requiring further follow-up; a
 cervical smear has to be taken at the screening visit, or a normal result has to be
 documented within the previous 6 months. Human papilloma virus (HPV) testing in
 subjects with atypical squamous cells of undetermined significance (ASCUS) can be used
 as an adjunctive test. Subjects with ASCUS can be included if they are negative for
 high-risk HPV strains.

 before start of treatment)

 -  Any diseases or conditions that can compromise the function of body systems and could
 result in altered absorption, excessive accumulation, impaired metabolism, or altered
 excretion of the study medication

 -  Any diseases or conditions that might interfere with the conduct of the study or the
 interpretation of the results

 -  Any disease or condition that may worsen under hormonal treatment according to the
 assessment and opinion of the investigator.
