Puravive and Disopyramide Phosphate

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Puravive interacts with whole categories of medication. Disopyramide Phosphate falls into 2 of those categories, so it can interact with Puravive in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

Qt Interval-Prolonging Drugs

1 of 2

Why this applies to Disopyramide Phosphate

Disopyramide Phosphate falls under Qt Interval-Prolonging Drugs — the group Puravive interacts with.

Puravive contains Panax ginseng. Panax ginseng is thought to have an additive effect with drugs that prolong the QT interval, potentially increasing the risk of ventricular arrhythmias. However, research findings on this matter are conflicting. Clinical studies indicate that short-term use of Panax ginseng can increase the QT interval (source: https://pubmed.ncbi.nlm.nih.gov/27240158/). However, no changes in the QT interval have been observed with prolonged use (source: https://pubmed.ncbi.nlm.nih.gov/11978148/).
Severity Moderate Likelihood Possible Evidence C

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.

Here's the thing to know if you take disopyramide (Norpace) and are eyeing Puravive. Disopyramide is an antiarrhythmic that already stretches out your heart's electrical reset time, what doctors call the QT interval. Puravive contains Panax ginseng, which a few short-term studies suggest can lengthen the QT interval too. Stacking the two could, in theory, add up and raise the small but real risk of a dangerous heart rhythm.

I want to be honest that the evidence here is mixed and fairly weak. Some studies showed a QT change with ginseng, others showed none with longer use. Still, because disopyramide is a drug where rhythm matters a lot, I wouldn't combine them on your own. Please check with your pharmacist or doctor first.

Cytochrome P450 3A4 (Cyp3A4) Substrates

2 of 2

Disopyramide Phosphate also falls under Cytochrome P450 3A4 (Cyp3A4) Substrates.

Puravive contains Panax ginseng. Panax ginseng has the potential to affect the breakdown of drugs that are metabolized by an enzyme called CYP3A4. One example of such a drug is imatinib. There was a case where imatinib was thought to have caused liver damage, and it was believed that this might have been due to Panax ginseng inhibiting CYP3A4, which is involved in imatinib's metabolism (https://pubmed.ncbi.nlm.nih.gov/20332334/). On the other hand, Panax ginseng has been found to increase the breakdown of another drug called midazolam, which is also metabolized by CYP3A4 (https://pubmed.ncbi.nlm.nih.gov/21646440/), suggesting Panax ginseng induces CYP3A4 in some cases (i.e., makes more potent). Given these contradictory findings, it is important to use Panax ginseng cautiously if you are taking medications that are metabolized by CYP3A4, as the interaction between Panax ginseng and these drugs is not fully understood.
Severity Minor 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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist: Puravive contains Panax ginseng, which can tug on a liver enzyme called CYP3A4. That enzyme is one of the pathways your body uses to clear disopyramide (Norpace). The tricky part is that ginseng has gone both ways in studies, sometimes slowing this enzyme and sometimes speeding it up, so we honestly can't predict the direction with confidence.

Disopyramide is an antiarrhythmic, and it isn't a drug you want bouncing up and down. If levels rise, you could see more dry mouth, blurry vision, trouble urinating, or heart rhythm changes. If levels drop, your irregular heartbeat could come back. The evidence here is weak and mostly theoretical, but because this is a sensitive heart medicine, please check with your pharmacist or doctor before adding Puravive.

From our pharmacist’s overview on the Disopyramide Phosphate page

“Grapefruit is the first thing I would set aside on disopyramide phosphate (Norpace), a medicine that steadies dangerous heart rhythms, because grapefruit juice can push the drug's blood level up. That pattern dominates the page, since 121 of the 169 flagged ingredients act on the same liver enzyme, CYP3A4, raising the drug's level or,…”

About Puravive

What is Puravive?

Puravive
  • Weight management
  • Metabolism support
  • Energy levels
  • General wellness
  • Stress and brain health

Puravive is a branded, multi-ingredient capsule marketed mainly for weight loss by claiming to boost brown fat activity, but there is no published, independent clinical research showing the product itself works for this purpose. Some individual ingredients have been studied in laboratory or small human studies, but those results do not prove the finished blend is safe or effective. Talk to a pharmacist or doctor before trying it, especially if you have health conditions or take medications.

About Disopyramide

What Is Disopyramide Used For?

Brand names: Norpace CR, Norpace

Disopyramide — available as Disopyramide Phosphate, Norpace, and Norpace CR — is indicated for the treatment of documented ventricular arrhythmias, such as sustained ventricular tachycardia (a fast, dangerous heart rhythm originating in the lower chambers), that a physician judges to be life-threatening.

Because of its potential to worsen heart rhythm problems, it is generally not recommended for lesser arrhythmias, and it should not be used to treat ventricular premature contractions (extra heartbeats) that cause no symptoms. Treatment is typically started in a hospital setting.
