Comparative Effects of Perindopril and Zofenopril on Blood Pressure Control and Oxidative Status Blacks Hypertensive Patients.

Rationale and Design of a Simple Randomized Trial Evaluating Comparative Effects of Perindopril and Zofenopril in Blacks Hypertensive Patients: Short Term Effects on Cardiac and Oxidative Status With Perindopril or Zofenopril (PEZO-HP) Trial

The aim of the study is to compare the short term effect of perindopril and zofenopril in the management of hypertension and the oxydative stress in blacks hypertensive patients.

PEZO-HP is a double-arm, double-blind, randomized and parallel clinical trial conducted at the Yaoundé Central Hospital.

Aim: to determine and compare the short term effect of angiotensin converting in the management of hypertension as well as the oxidative effect of Zofenopril and perindopril in blacks hypertensive patients in the Yaoundé Central Hospital.

Method: A double-arm, double-blind, randomized and parallel clinical trial conducted at the Yaoundé Central Hospital. Hypertensive patients who are not taking angiotensin-converting enzyme inhibitor or angiotensin receptors blockers, are randomize into 2 groups. Depending on the group, the intervention consisted of the administration of Perindopril 10 mg daily or Zofenopril 30 mg daily for 08 weeks. The endpoints were the nycthemeral blood pressure profile, pro oxidant marker (malondialdehyde) and anti-oxidant marker (Ferric reducing antioxidant).

Progress: Recruitment for PEZO-HP was completed in May 2019 with 24 patients.
