Elevated Blood Pressure, Metabolic Syndrome
Conditions
Brief summary
A prospective, multicenter, randomized controlled study evaluating the efficacy and safety of a Nigella sativa extract standardized to 10% thymoquinone (Nisatol®) in perimenopausal women with metabolic syndrome. The study will assess changes in metabolic and blood pressure parameters, as well as improvements in menopausal symptoms and quality of life.
Detailed description
This prospective, multicenter, randomized controlled clinical trial aims to evaluate the efficacy and safety of a food supplement containing Nigella sativa oil standardized to 10% thymoquinone (Nisatol®) in perimenopausal women diagnosed with metabolic syndrome and experiencing climacteric symptoms. Fifty participants will be randomly assigned to either the intervention group (receiving 2 softgel capsules of Nisatol® daily for 4 months) or a control group following a Mediterranean diet. The primary endpoint is the change from baseline in metabolic and blood pressure parameters, including fasting glucose, lipid profile, cortisolemia, uricemia, and systolic/diastolic blood pressure. The study will also assess quality of life using the Greene Climacteric Scale and monitor treatment safety and tolerability. The study addresses the need for non-hormonal, evidence-based interventions for managing metabolic and menopausal symptoms in midlife women.
Interventions
Participants will follow a Mediterranean diet for 4 months under dietary guidance, without receiving any Nigella sativa supplementation.
Participants will take 2 softgel capsules daily of Nigella sativa oil standardized to 10% thymoquinone (Nisatol®), one capsule with lunch and one with dinner, for 4 months.

Intervention model description

Design outcomes
Primary
| Measure | Time frame | Description |

| Change in Serum Uric Acid levels, (mg/dL) | Baseline to 4 months | Evaluation of Uric acid levels from baseline to 4 months. |
| Change in Fasting Blood Glucose | Baseline to 4 months | Evaluation of the change in fasting blood glucose from baseline to 4 months. |
| Change in Total Cholesterol levels, (mg/dL) | Baseline to 4 months | Evaluation of total cholesterol from baseline to 4 months. |
| Change in low-density lipoprotein cholesterol levels, (mg/dL) | Baseline to 4 months | Evaluation of low-density lipoprotein cholesterol from baseline to 4 months. |
| Change in high-density lipoprotein cholesterol levels, (mg/dL) | Baseline to 4 months | Evaluation of high-density lipoprotein cholesterol from baseline to 4 months. |
| Change in Triglycerides levels, (mg/dL) | Baseline to 4 months | Evaluation of triglyceride levels from baseline to 4 months. |
| Change in Blood Pressure | Baseline to 4 months | Evaluation of the change in systolic and diastolic blood pressure from baseline to 4 months. |
| Change in serum Alanine Aminotransferase Enzyme levels, (U/L) | Baseline to 4 months | Evaluation of Alanine Aminotransferase Enzyme levels from baseline to 4 months. |
| Change in serum Aspartate Aminotransferase Enzyme levels, (U/L) | Baseline to 4 months | Evaluation of Aspartate Aminotransferase Enzyme levels from baseline to 4 months. |
| Change in serum Change in Serum Creatinine levels, (mg/dL or µmol/L) | Baseline to 4 months | Evaluation of serum creatinine from baseline to 4 months. |
| Change in serum Creatine Phosphokinase Enzymes levels, (U/L) | Baseline to 4 months | Evaluation of Creatine Phosphokinase Enzymes levels from baseline to 4 months. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Safety and Tolerability | Throughout study duration (4 months) | Evaluation of adverse events, tolerability score (0-10), and adherence rate (%) over the 4-month treatment period. |
