What is the most effective ace inhibitor?

Let’s face it, people have been trying to find the perfect ACE inhibitor for years. You might even say that this quest is like searching for the lost city of El Dorado or the fountain of youth. But in reality, it’s more like trying to find a decent parking spot at Target on Black Friday.

ACE inhibitors are used to treat high blood pressure and heart failure by blocking an enzyme called angiotensin-converting enzyme (ACE). This leads to a decrease in the production of angiotensin II, which is responsible for narrowing blood vessels and increasing blood pressure. So which one is the most effective? Let’s take a closer look.

Background on ACE Inhibitors

Before we can dive into our search, let’s first discuss what ACE inhibitors are and how they work. As mentioned before, these medications block ACE from producing angiotensin II, which allows your blood vessels to relax and widen. This leads to a decrease in blood pressure and helps your heart pump more efficiently.

There are currently nine different types of ACE inhibitors available on the market today. All of them have similar mechanisms of action but differ slightly in their structure and side effects.

Examining Each Type


Benazepril is known as an “ester prodrug” due to its inactive form when initially ingested (bet you didn’t know that). It must be converted into its active form by liver enzymes before it can start working within your body .(pretty cool right) . Its advantages include being less likely than other drugs in its class- including lisinopril -to cause coughing (less hacking=win)


As one could guess based off literal meaning behind ‘pharmaceutical terminology’, captopril contains sulfur (that’s science for you). However, it also has a short half-life which will likely require multiple doses per day (joy) . Upset stomach and rash are listed as potential side effects.


Despite having a similar structure to captopril (minus the sulfur), enalapril converts better in the liver and doesn’t need multiple daily dosages (relief-at-last) . It is available in tablet form but can also be given intravenously in emergency medical situations (your veins won’t have to wait too long for relief) .


Fosinopril starts out as an inactive prodrug but actually reaches its full effect with ease when ingested (‘I am not just promises’ – fosinopril). This type of ACE inhibitor’s decreased risk of causing angioedema make it a common choice among healthcare providers(sign me up!)


Probably one you’ve heard: lisinopril remains one of the most popular options due to the effectiveness of treatment, Long-acting., only needing once-per-day dosage, being affordable ,and honestly who could forget that cough (read that sarcastically).


Due partly to its extended-half life feature, moexiprit tends to decently lower Blood pressure level when used once daily action.(N.B-without) food intake affects)


Perindopor(i)l produces closely related antihypertensive effect despite if being more potent than others overall across-the-board  including use for heart failure,symptoms improvement ability,potentials in slowing down negative cardiovascular outcomes.

Additionally there are two other less commonly-used ace inhibitors: quinalapril and trandolapril.

The Winner (Drum Roll Please)

And the winner is…drumroll please…lisinopril! Despite its infamous side effect of coughing, it’s still one of the most commonly-prescribed ACE inhibitors due to its effectiveness and affordability. Plus, with a once-per-day dosage, you won’t have to worry about constantly taking your meds.

While there are slight differences between each type of ACE inhibitor regarding efficacy and side effects [see above], ultimately it comes down to what works best for you as an individual. Make sure to speak with your healthcare provider before switching or starting any new medication regimen.

This quest may not have led us to discovering the Holy Grail of ACE inhibitors (since we now know that lisinopril holds top spot), but hopefully our journey has provided insight into these important medications used in treating hypertension and heart failure.

After all, who says science can’t be fun?
