VERONICA-Nigeria: Improving BP control in Africa with a simple strategy

A triple pill protocol to reduce blood pressure (BP) among Nigerian patients with hypertension yielded excellent efficacy results and a good safety profile, demonstrating that a simple treatment protocol can strongly improve the current standard-of-care for this population.

The investigator-initiated VERONICA-Nigeria trial randomised 300 self-identified Black African adults with uncontrolled hypertension from Nigeria 1:1 to a triple pill-based treatment protocol or to the standard-of-care Nigerian hypertension treatment protocol, which starts with 1 agent and may be changed to 2 agents if the result is insufficient. Prof. Dike Ojji (University of Abuja, Nigeria) and colleagues looked at the change in home-measured systolic BP at 6 months.

After 6 months of treatment, participants in the triple pill group had an average 5.8 mmHg lower systolic BP than those in the standard-of-care group. For diastolic BP, the corresponding number was 3.6 mmHg. Furthermore, 62% of the participants in the experimental arm versus 28% of those in the control arm had achieved a BP <130/80 (P<0.001).

“No patients in either study arm had discontinued treatment due to adverse events,” continued Dr Ojji. “The only safety issue we noticed was a slight increase in hypo-potassium (<3.5 mmol/L) in the triple pill arm (34% vs 18%).” When the researchers looked at participants with a potassium level <3.0 mmol/L, they noticed that the proportion had dropped from 34% to 9% in the experimental arm.

In conclusion, the triple pill protocol was more effective than the standard-of-care BP protocol in lowering BP in Black African patients. The BP control rate at 1 month was 80%, which was maintained throughout the study.
