Vasomotor syndrome is prevalent in 85% of postmenopausal women, hormone therapy in menopause is first-line therapy, but 38% of patients have some contraindication for its use. The medications indicated in this population presents adverse reactions, such as dryness of the mucous membranes, and insomnia in patients, and triggers to abandoned treatment due to poor response to the drug. Aligned with the safety of patients, we wish to test pomegranate seed oil with nanotechnology (NANOPSO), which has been reported to have positive results at a central level, due to its antioxidant effect, which could impact women in climacteric in a positive way. The study involves the participation of 90 patients divided into two groups, where placebo or Nano-PSO will be administered for 60 days, with a total follow-up of 120 days. It is established that patients must not have received previous treatments for menopausal symptoms. Therefore, it is expected that therapy with NANO-PSO compared to placebo will be more effective in controlling vasomotor symptoms in early menopause after 6 months of treatment evaluated by the MRS scale.
