Evodia and Pasireotide Diaspartate

Here is the interaction we found between these two, with the evidence behind it.

Moderate

QT INTERVAL-PROLONGING DRUGS

Why this applies to Pasireotide Diaspartate

Pasireotide Diaspartate falls under QT INTERVAL-PROLONGING DRUGS — the group Evodia interacts with.

Theoretically, evodia might have an additive effect with drugs that prolong the QT interval, potentially increasing the risk of ventricular arrhythmias.
Evodia has demonstrated dose-dependent activity as a proarrhythmic agent in animal and in vitro studies. Evodia infusion in animals extends the action duration potential and induces prolongation of the QT interval and Torsade de pointes.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with pasireotide (Signifor): it's one of those medications that can stretch out a part of your heart's electrical cycle, known as the QT interval. Evodia has shown a similar QT-stretching effect, but only in test tube and animal studies, not in people. The worry is that stacking the two together could add up and, in rare cases, trigger an abnormal heart rhythm.

I want to be honest that this is mostly theoretical at this point, so I'm not trying to scare you. Still, since pasireotide already carries a QT caution of its own, I'd loop in your doctor or pharmacist before adding evodia. They may want a simple heart tracing (an EKG) or to check your potassium and magnesium to keep things safe.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

From our pharmacist’s overview on the Pasireotide Diaspartate page

“All 13 supplements on this page raise the same concern with pasireotide (Signifor), a drug for Cushing's disease that can itself lengthen the QT interval, the electrical reset time between heartbeats. Stack another QT-prolonging ingredient on top and the risk of a dangerous heart rhythm goes up, so treat these combinations with real care.”

About Pasireotide Injection

What Is Pasireotide Injection Used For?

Brand name: Signifor

Signifor (pasireotide subcutaneous injection) is used to treat Cushing's disease — a condition caused by a pituitary tumor that makes the body produce too much cortisol — in patients for whom pituitary surgery is not an option or did not cure the disease.

Signifor LAR (a long-acting intramuscular form of pasireotide) is approved to treat both acromegaly (a condition where the pituitary gland makes too much growth hormone) and Cushing's disease, in patients who have had an inadequate response to surgery or for whom surgery is not an option.
