Brief summary
We assessed the influence of time of administration of ACE inhibitors on circadian blood pressure control in sub Saharan type 2 diabetes patients with stage 1 hypertension over 56 days as first line treatment.
Detailed description
Background: Renin-angiotensin system antagonists represent the mainstay of blood pressure (BP) lowering treatment options in people with diabetes. ACE inhibitors have a long half-life and offer the advantage of a single daily dose, usually empirically taken in the morning. Objective: We assessed the influence of time of administration of ACE inhibitors on circadian BP control in type 2 diabetes (T2D) patients with stage 1 hypertension. Methods: Twenty T2D patients (9 being women) with a mean age of 58.7 years, diagnosed with stage 1 of hypertension and naive to BP lowering medications, were included. They were randomly allocated to receive perindopril 10 mg/day as a monotherapy either in the morning or in the evening for 28 days, with crossover without washout period on day 29th and additional 28 days follow-up. A 24-hour ambulatory BP monitoring (ABPM) was performed at baseline, days 28 and 56.
