Interaction report

Beta-methylphenethylamine (bmpea) and Dasatinib

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Dasatinib

Dasatinib 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

Your body clears dasatinib mainly through a liver enzyme called CYP3A4. Lab studies suggest BMPEA may block that enzyme by a little over a third. If that holds true in people, your dasatinib could clear more slowly and build up higher than intended. With dasatinib, that could mean more of its known side effects, such as fluid retention and swelling, low blood counts, bleeding or bruising, headache, tiredness, or trouble with heart rhythm (QT prolongation).

I'll be honest, this is a theoretical concern based on test-tube data, not real patient cases. Still, BMPEA is a risky, unapproved stimulant with its own heart effects, so I'd steer clear while on a cancer drug like this. Please run any supplement by your oncologist or pharmacist first.

From our pharmacist’s overview on the Dasatinib page

“Grapefruit is the first thing I would take off the table for anyone on dasatinib (Sprycel, Phyrago), a targeted leukemia therapy where a steady blood level is the whole point of treatment. It blocks CYP3A4, the enzyme that clears dasatinib, letting levels climb, and 121 of the 146 supplements on file act on that same pathway.”

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 Dasatinib

What Is Dasatinib Used For?

Brand names: Sprycel, Phyrago

Dasatinib tablets (available as Sprycel, Phyrago, and generic dasatinib) treat Philadelphia chromosome-positive (Ph+) chronic myeloid leukemia (CML) in adults — both newly diagnosed cases in chronic phase and more advanced phases of CML when prior treatment including imatinib has stopped working or caused intolerable side effects. They are also used for adults with Ph+ acute lymphoblastic leukemia (Ph+ ALL) when prior therapy has not worked.

For pediatric patients aged 1 year and older, Sprycel and Phyrago are indicated for Ph+ CML in chronic phase, as well as newly diagnosed Ph+ ALL in combination with chemotherapy. Generic dasatinib tablets are indicated for pediatric patients with Ph+ CML in chronic phase; additional pediatric Ph+ ALL use is specifically approved for Sprycel.
