Puravive and Diltiazem, Enalapril

These two interact in 3 distinct ways. Each one is explained separately below.

Why Are There 3 Interactions?

Puravive interacts with whole categories of medication. Diltiazem, Enalapril falls into 3 of those categories, so it can interact with Puravive in 3 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Minor).

Minor

Cytochrome P450 3A4 (Cyp3A4) Substrates

1 of 3

Why this applies to Diltiazem, Enalapril

Diltiazem, Enalapril falls under Cytochrome P450 3A4 (Cyp3A4) Substrates — the group Puravive interacts with.

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 explains PharmD, Clinical Pharmacist

The combo pill Teczem pairs diltiazem (a calcium channel blocker) with enalapril (an ACE inhibitor) to manage blood pressure. The diltiazem half is handled by the CYP3A4 enzyme, and Puravive contains Panax ginseng, which can nudge that enzyme in either direction. If ginseng slows CYP3A4, diltiazem could build up, which might mean more dizziness, a slower heart rate, swollen ankles, or blood pressure dropping too low. If ginseng instead speeds the enzyme up, diltiazem may work less well.

Honestly, the evidence here is thin and contradictory, so this is a low-concern, theoretical interaction. Still, since blood pressure control matters, run Puravive past your pharmacist or doctor before starting it, and don't change your Teczem on your own.

Antihypertensive Drugs

2 of 3

Diltiazem, Enalapril also falls under Antihypertensive Drugs.

Puravive contains quercetin, which has been found to slightly reduce blood pressure in individuals with mild hypertension (https://pubmed.ncbi.nlm.nih.gov/17951477/). There is a theoretical possibility that it could enhance the blood pressure-lowering effects of antihypertensive medications.
Severity Minor 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.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Teczem combines two blood pressure medicines: diltiazem (a calcium channel blocker) and enalapril (an ACE inhibitor). Puravive contains quercetin, which in one small study slightly lowered blood pressure in people with mild high blood pressure. So in theory, pairing it with your medication could nudge your blood pressure a little lower than usual.

I want to be honest with you here: this is a minor, theoretical concern based on weak evidence, not something that happens to most people. Still, if your numbers dipped too far, you might feel lightheaded, dizzy, tired, or notice a faster heartbeat. If you decide to try Puravive, just keep an eye on your readings and how you feel, and check in with your pharmacist or doctor first.

Minor

P-Glycoprotein Substrates

3 of 3

Diltiazem, Enalapril also falls under P-Glycoprotein Substrates.

Puravive contains quercetin. Theoretically, concurrent use of quercetin and P-glycoprotein substrates might alter the effects and adverse effects of the drugs. There is preliminary evidence suggesting that quercetin inhibits the P-glycoprotein efflux pump in the gastrointestinal tract. This inhibition could potentially increase the bioavailability and serum levels of drugs transported by this pump. For example, a small study in healthy volunteers found that pretreatment with quercetin increased bioavailability and plasma levels following a single dose of cyclosporine (Neoral, Sandimmune) (source: https://pubmed.ncbi.nlm.nih.gov/15581264/). However, other small studies have shown that quercetin might decrease the absorption of talinolol, another substrate of the gastrointestinal P-glycoprotein efflux pump. Interestingly, several days of quercetin treatment did not significantly affect the pharmacokinetics of saquinavir (Invirase) in another small study (source: https://pubmed.ncbi.nlm.nih.gov/16945047/). The reason for these discrepancies is not entirely clear. Until more is known, it is advisable to use quercetin cautiously in combination with P-glycoprotein substrates.
Severity Minor 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.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for your Teczem (which combines diltiazem and enalapril). Puravive contains quercetin, and there's some early lab and small-study evidence that quercetin can block a gut transporter called P-glycoprotein. Diltiazem moves through that pump, so in theory blocking it could let a bit more diltiazem into your bloodstream. If that happened, you might notice more of diltiazem's usual effects, like a slower heart rate, lower blood pressure, dizziness, or swelling in your ankles.

I want to be honest though: this is mostly theoretical, the rating is minor, and quercetin's effects on this pump have been inconsistent across studies. I'd still chat with your pharmacist or doctor before adding Puravive, since both blood pressure medicines deserve a careful eye. Don't change anything on your own.

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.
