What this trial studies

This clinical trial investigates the impact of 12 weeks of melatonin supplementation on cardiovascular disease mechanisms in women experiencing perimenopause and hypertension. Participants will receive either melatonin or a placebo to assess changes in blood pressure and related cardiovascular markers. The study aims to determine if melatonin can provide a therapeutic benefit during this transitional phase of menopause. The trial is designed to include women aged 40-55 who meet specific criteria regarding their menstrual cycle and hypertension status.

Who should consider this trial

Good fit: Ideal candidates are women aged 40-55 in the menopause transition with a diagnosis of hypertension.

Not a fit: Patients who are currently using prescription sleeping medications or hormonal contraceptives may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for managing hypertension in women undergoing menopause.

How similar studies have performed: While there is limited research specifically on melatonin for cardiovascular health in menopause, similar studies on melatonin's effects on hypertension have shown promising results.
