Brief Summary
Introduction: Cardiovascular diseases (CVD) are the main cause of death in Western countries. High levels of homocysteine (He) has been considered an important risk factor for coronary artery disease. Objective: To evaluate the effects of the drug Tenavit® (pyridoxine hydrochloride 4.00mg + folic acid 0.80mg + cyanocobalamin 0.40 mg) on plasma homocysteine concentrations and lipid profile in postmenopausal women. Methods: Sixty women were postmenopausal selected from the outpatient Gynecology Hospital Santa Marcelina that passed by routine consultations and fulfilling the inclusion criteria were invited to the study. The women were randomly allocated to control or experimental group (30 in each group) in a do uble-blind controlled clinical trial. The experimental group received one tablet of Tenavit® daily and the placebo group received the same tablet with the organoleptic characteristics of Tenavit® for a period of 4 months. The women were assessed before the intervention and after 4 months of medication. A self-report questionnaire to assess quality of life (QSF-36) was applied and anthropometric measurements, cholesterol and fractions, triglycerides, fasting glucose, homocysteine and cysteine were evaluated. Results: The only variable that presented significant alteration in both dimensions (between and within group) was the homocysteine. It was observed statistical significant between groups in the final measure for homocysteine (control group: 11.5mmol/ L; experimental group: 9.4 mmo

Outcome Measures
Primary Outcomes (1)
supplementation may be beneficial in postmenopausal patients, with the intention to reduce the level of homocysteine
supplementation may be beneficial in postmenopausal patients, with the intention to reduce the level of homocysteine and, thus, reduce the cardiovascular risk in this age.
The women were assessed before the intervention and after 4 months of medication.
Study Arms (2)
Placebo Oral Tablet
PLACEBO COMPARATORSixty women were postmenopausal selected from the outpatient Gynecology Hospital Santa Marcelina that passed by routine consultations and fulfilling the inclusion criteria were invited to the study. The women were randomly allocated to control or experimental group (30 in each group) in a double-blind controlled clinical trial. The control group received the same tablet with the organoleptic characteristics of Tenavit® for a period of 4 months.
Experimental group (Tenavit®)
EXPERIMENTALSixty women were postmenopausal selected from the outpatient Gynecology Hospital Santa Marcelina that passed by routine consultations and fulfilling the inclusion criteria were invited to the study. The experimental group received one tablet of Tenavit® (pyridoxine hydrochloride 4.00mg + folic acid 0.80mg + cyanocobalamin 0.40 mg) daily and the placebo group received the same tablet with the organoleptic characteristics of Tenavit® for a period of 4 months.
Interventions
The experimental group received one tablet of Tenavit® daily for a period of 4 months.
Placebo group received the same tablet with the organoleptic characteristics of Tenavit® for a period of 4 months.
