What this trial studies

This clinical trial evaluates the effects of melatonin on women experiencing symptoms related to perimenopause. It is a randomized, double-blind, placebo-controlled study involving 40 participants, where half will receive melatonin and the other half a placebo for 30 days. Participants will undergo interviews, complete questionnaires, and provide blood and urine samples for analysis before and after the treatment period. The study aims to assess any changes in symptoms and overall well-being during the treatment.

Who should consider this trial

Good fit: Ideal candidates are women aged 45 and older who are in perimenopause and have experienced irregular menstrual cycles.

Not a fit: Patients with a history of substance abuse, neurological or oncological diseases, ischemic heart disease, liver failure, renal insufficiency, or those currently using certain medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new non-hormonal treatment option for alleviating perimenopausal symptoms.

How similar studies have performed: While the use of melatonin for various conditions has been explored, this specific application for perimenopausal symptoms is relatively novel and has not been extensively tested.
