Interaction report

Beta-methylphenethylamine (bmpea) and Mobocertinib Succinate

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Mobocertinib Succinate

Mobocertinib Succinate falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Beta-methylphenethylamine (bmpea) interacts with.

Theoretically, BMPEA might increase the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that BMPEA inhibits CYP3A4 by up to 37%.
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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with these two. Your cancer medicine, mobocertinib (Exkivity), gets broken down in the body by an enzyme called CYP3A4. In lab dishes, BMPEA appears to slow that enzyme down by roughly a third. If that holds true in people, your body would clear mobocertinib more slowly, letting it build up to higher levels than intended.

That matters because mobocertinib already carries a real risk of heart rhythm changes (a longer QT interval), along with diarrhea, nausea, and mouth sores. Higher levels could make these worse. On top of that, BMPEA is a stimulant that can raise heart rate and blood pressure on its own, which is a poor combination here. This is theoretical, but please don't pair them without checking with your oncology team first.

From our pharmacist’s overview on the Mobocertinib Succinate page

“Mobocertinib (Exkivity) is a targeted therapy for a hard-to-treat lung cancer, which makes dosing precision matter and this list worth real caution. Most of the 146 supplements on file can shift the drug's blood level, because mobocertinib is cleared by CYP3A4, an enzyme many botanicals speed up or slow down.”

About Beta-methylphenethylamine (bmpea)

What is Beta-methylphenethylamine (bmpea)?

  • Weight loss
  • Pre-workout energy
  • Athletic performance
  • Appetite suppression
  • Mental focus

Beta-methylphenethylamine (BMPEA) is a synthetic stimulant chemically similar to amphetamine that has been found in some weight-loss and sports supplements, often without being clearly listed on the label. It is not an approved or well-studied dietary ingredient, and regulators have warned that it may carry real cardiovascular risks. Because of safety concerns and the lack of human research, it is best avoided.

About Mobocertinib

What Is Mobocertinib Used For?

Brand name: Exkivity

  • Mobocertinib is used to treat a certain type of non-small cell lung cancer (NSCLC) that cannot be removed by surgery and has spread to other parts of the body either during or after treatment with platinum chemotherapy medications. Mobocertinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop or slow the spread of cancer cells and may help shrink tumors.
