Ornithine Ketoglutarate (okg) + Quinapril
Quinapril brand names: Accupril, Accupro.
We found no known interaction between Ornithine Ketoglutarate (okg) and Quinapril in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.
Ornithine Ketoglutarate (okg) and Quinapril
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Quinapril and Ornithine Ketoglutarate (okg) in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
Worth understanding: our licensed dataset holds no drug-interaction record for Ornithine Ketoglutarate (okg) at all — not against Quinapril, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What Quinapril Is Prescribed For, and What Ornithine Ketoglutarate (okg) Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. Quinapril is a prescription medicine with approved uses on its FDA label. Ornithine Ketoglutarate (okg) is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Quinapril is prescribed for: Quinapril tablets are used to lower high blood pressure. Lowering blood pressure reduces the risk of strokes and heart attacks. It can be used alone or with a thiazide diuretic (water pill). It is also used to help manage heart failure.

For this use, it is added to usual treatment such as diuretics and/or digitalis.

Stroke studied, not established Ornithine Ketoglutarate (okg) has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Ornithine Ketoglutarate (okg) for stroke
It is unclear if oral ornithine ketoglutarate is beneficial in patients with a recent stroke.
Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Quinapril on your own; if you are taking Ornithine Ketoglutarate (okg) for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Quinapril page
“Quinapril (Accupril) lowers blood pressure by relaxing blood vessels, and that is where most of the 166 supplements and herbs on this list collide with it. The bulk either push its blood-pressure-lowering effect too far or work against it, and with six entries rated major, this page deserves a careful read, not a skim.”
