ACE Inhibitor (Blood Pressure Medicine)
Last reviewed July 2026
Who is this for?
Enalapril is a blood pressure-lowering medicine that works by relaxing your blood vessels so blood can flow more easily, reducing the pressure on your heart.
Inhibits angiotensin-converting enzyme (ACE), preventing the conversion of angiotensin I to angiotensin II and reducing vasoconstriction, aldosterone secretion, and sodium retention. This results in decreased peripheral vascular resistance, lower blood pressure, and reduced cardiac workload.
High blood pressure (hypertension), heart failure, prevention of heart problems in people with weak hearts

If you miss a dose, take it as soon as you remember. But if it is almost time for your next dose, skip the missed one and continue your normal schedule. Do not take two tablets at once to make up for it.
This is a prescription medicine, so do not buy from roadside sellers or use someone else's blood pressure tablets, as the wrong dose can be dangerous. Do not stop taking it suddenly because you feel fine; high blood pressure often has no symptoms but still damages your body. If you develop a persistent dry cough, tell your doctor, as they may switch you to a different medicine.
Avoid using potassium supplements or salt substitutes that contain potassium while on this drug, as it can cause dangerously high potassium levels. NSAIDs like ibuprofen (commonly sold in Nigeria) can reduce how well enalapril works and may harm your kidneys. Alcohol can increase the blood pressure-lowering effect and make you feel very dizzy or faint.
