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.

Inclusion Criteria:

• Hypertensive patients
• On a stable atihypertensive therapies (determined by the investigator) for at least 3 months with no classes changes. The pharmacological treatment should not include an angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker
• Subject must not present any contraindication to exercise
• Before any study-specific procedure, the appropriate written informed consent must be obtained.

Exclusion Criteria:

• Side effects affecting life quality of patients (determined by the Data Safety Monitoring Board).
• Withdrawal of consent

The double-blind model is applied to the study. Only the adjudicator, responsible for the distribution of medication knew the different regimes. Perindopril and Zofenopril were packaged in boxes of identical appearance and labeled for each participant by name and number of the randomization program. The randomization and packaging of the drugs was done by an investigator who had no clinical involvement.
