Background: Hypertension increases the incidence of congestive heart failure, myocardial infarction, and ischemic stroke. In previous studies, metoprolol succinate extended release (XL) has been identified as a plausible antihypertensive medication compared to others. Apart from angiotensin II receptor antagonists, this β-blocker effectively reduces mortality and hospitalisation rate due to cardiovascular accidents. Aim: The aim was to identify the impact of metoprolol succinate XL 50/100mg on hypertensive patients for 3 months as part of a post-market surveillance study involving the African population. Methods: Out of 200 patients, a total of 184 patients were enrolled on the study. Results: Metoprolol succinate XL led to a significant decrease in the mean systolic blood pressure (SBP), mean diastolic blood pressure (DBP), and mean heart rate (HR) at 4th, 8th, and 12th-week from baseline (p<0.0001). 39.50%, 18%, 61.50%, and 45.50% of patients went from Grade 1 to normal, Grade 2 to Normal, High Normal to Normal and isolated systolic hypertension to Normal categories of BP, respectively. Large effect size was noticed in analyses, as estimated by Cohen’s d-value, which implied a practical significance of using the drug in the study population with respect to lowering BP and HR. Mean SBP, DBP, and HR change was higher in the baseline to 4-week, 8-week, and 12-week groups compared to inter-weekly changes. Moreover, mean baseline SBP and DBP were higher in groups administered with 50mg of the drug. Conclusion: These findings suggest that metoprolol succinate XL 50/100mg significantly lowers mean BP and HR among African hypertensive patients.
