Amlodipine and Coenzyme Q10, a synergy.

CoQ10 produces a small but consistent reduction in systolic blood pressure (about 3-5 mmHg) and improves endothelial function, complementing amlodipine's antihypertensive effect. The combination is generally beneficial and well-tolerated, especially in patients with metabolic syndrome or coexisting heart failure.

Synergy

What is happening. CoQ10 produces a small but consistent reduction in systolic blood pressure (about 3-5 mmHg) and improves endothelial function, complementing amlodipine's antihypertensive effect. The combination is generally beneficial and well-tolerated, especially in patients with metabolic syndrome or coexisting heart failure.

Mechanism. CoQ10 improves mitochondrial energy production in vascular smooth muscle and endothelium, raising nitric oxide bioavailability and reducing systemic vascular resistance. These effects add to amlodipine's vasodilation.

Recommendation. CoQ10 at 100-200 mg/day combined with amlodipine is appropriate for most patients with hypertension or cardiometabolic disease. Monitor blood pressure for 4 weeks after starting, and adjust amlodipine with your prescriber if readings fall consistently below your goal.
