Bacopa and Ropivacaine

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

Moderate

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

Why this applies to Ropivacaine

Ropivacaine falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Bacopa interacts with.

Theoretically, bacopa might increase the levels and adverse effects of CYP1A2 substrates.
Research on the effects of bacopa extracts on CYP1A2 enzymes is conflicting. Some in vitro evidence shows that bacopa extract can moderately and non-competitively inhibit CYP1A2, while other in vitro evidence suggests that any effect is unlikely to be clinically significant.
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 situation with these two. Ropivacaine (Naropin) is a local anesthetic, the kind of numbing medicine given during surgery, childbirth (think epidurals), or certain procedures. Your liver clears it largely through an enzyme called CYP1A2. In the test tube, bacopa might slow that enzyme down a bit, which could in theory let ropivacaine build up. If levels climbed too high, you could see signs like ringing in the ears, a metallic taste, dizziness, numbness around the mouth, or, rarely, heart rhythm and nervous system effects.

That said, the evidence here is weak and comes only from lab studies, and the findings even disagree with each other. Ropivacaine is also usually dosed and watched by your anesthesia team. Still, it's worth mentioning your bacopa to your doctor or pharmacist before any planned procedure.

From our pharmacist’s overview on the Ropivacaine page

“Fever bark stands apart on this page. It carries the only major rating among the 85 supplements and herbs on file for ropivacaine (Naropin), the numbing medicine used in epidurals and nerve blocks, because reserpine, one of its compounds, has been tied to unstable blood pressure and heart function during general anesthesia.”

About Bacopa

What is Bacopa?

Bacopa
  • Memory and cognitive support
  • Anxiety and stress
  • ADHD symptoms
  • Age-related memory decline
  • General brain health

Bacopa is an Ayurvedic herb most often used for memory and thinking. Some small studies suggest it may modestly help memory when taken regularly for several weeks, but the evidence is limited and quality varies. It is generally well tolerated but can cause stomach upset, and it should be avoided in pregnancy and breastfeeding due to a lack of safety data.
