Research led by Sichuan University in China has revealed that bedtime antihypertensive medication dosing improves nocturnal blood pressure control over morning dosing in patients with hypertension.

Hypertension is a major global health challenge. In China, nearly 300 million individuals live with elevated blood pressure and fewer than 17% achieve adequate control. Nocturnal pressure is often the most difficult to manage and can be a better predictor of heart attack and stroke than daytime readings.

Previous studies have examined the optimal timing for antihypertensive medication with conflicting evidence and substantial variability in study outcomes.
