The bottom line No known interaction

We found no known interaction between Hordenine and Ticagrelor 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.

Hordenine and Ticagrelor

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 Ticagrelor and Hordenine 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.

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.

How we checked

Why No Interaction Is Listed for Ticagrelor

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ticagrelor is filed under 5 classifications — including anticoagulant/antiplatelet drugs, cytochrome p450 3a4 (cyp3a4) inhibitors, cytochrome p450 3a4 (cyp3a4) substrates. Hordenine has documented interactions with 3 drug classes — the most serious being monoamine oxidase inhibitors (maois) (moderate), stimulant drugs (moderate) and cytochrome p450 2d6 (cyp2d6) substrates (minor) — and none of Ticagrelor’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

What Hordenine Itself Has Been Linked To

This is not an interaction — nothing below involves Ticagrelor. It is the side-effect record for Hordenine on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Hordenine, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Raised blood pressure Worth acting on Additional detail

    “No clinical studies have evaluated the safety of hordenine in humans. However, hordenine is structurally similar to the stimulants N-methyltyramine and synephrine, which are found in bitter orange. Theoretically, hordenine may cause stimulant-related side effects similar to these compounds, including tachycardia and hypertension.”

Everything above comes from the Natural Medicines adverse-effect record for Hordenine — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Ticagrelor’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Ticagrelor column appears here.

See Every Supplement That Interacts With Ticagrelor

This page covers Hordenine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Ticagrelor page lists 286 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Danshen (major), Grapefruit (major), Piracetam (major) and St. John's Wort (major).

By severity: 5 major · 241 moderate · 40 minor.

From our pharmacist’s overview on the Ticagrelor page

“Grapefruit sits at the top of this list for good reason. Ticagrelor (Brilinta) is cleared by the CYP3A4 enzyme, and grapefruit blocks that enzyme, so drug levels can climb and bleeding becomes more likely.”

About Hordenine

What is Hordenine?

Hordenine
  • Energy and stimulation
  • Athletic and workout performance
  • Weight loss/fat burning
  • Focus and mood
  • Appetite control

Hordenine is a natural alkaloid found in barley and some cacti that is marketed as a stimulant for energy, focus, and fat loss, but solid human evidence for these benefits is lacking. Its safety in people has not been well studied, so caution is warranted, and it should be avoided in pregnancy, breastfeeding, and by people with heart conditions.

Alkaloid isolated from plants such as barley sprouts and certain cacti · Capsules, tablets, powders (often in pre-workout and 'fat burner' blends)

An interaction check asks whether these two react with each other — it does not ask whether Hordenine is a good idea for someone in your situation. Here is what our Hordenine record says about it on its own.

Hordenine: dosing

There is no established, well-studied dose for hordenine. The amounts found in supplements vary widely, and they have not been tested for safety or effectiveness in proper human trials.If you choose to use a product containing hordenine, follow the label instructions and do not exceed them. Be aware that it is often mixed with caffeine and other stimulants, so the total stimulant load may be higher than it appears.

About Ticagrelor

What Is Ticagrelor Used For?

Brand name: Brilinta

Ticagrelor tablets are used to lower the risk of cardiovascular death, heart attack (myocardial infarction), and stroke in adults who have had acute coronary syndrome (ACS) — a group of conditions including unstable angina and heart attack — or who have a history of heart attack. It also reduces the risk of stent thrombosis (a blood clot forming in a coronary stent) in people who have been stented for ACS treatment.

Ticagrelor tablets are also used in people with coronary artery disease (CAD) who are at high risk for a first heart attack or stroke, particularly those with type 2 diabetes. Additionally, Brilinta is approved to reduce the risk of stroke in adults with a mild acute ischemic stroke or a high-risk transient ischemic attack (TIA, or "mini-stroke").
