Bacopa and Edrophonium, Atropine

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

Why Are There 2 Interactions?

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

Moderate

ANTICHOLINERGIC DRUGS

1 of 2

Why this applies to Edrophonium, Atropine

Edrophonium, Atropine falls under ANTICHOLINERGIC DRUGS — the group Bacopa interacts with.

Theoretically, concurrent use might decrease the effectiveness of both agents.
Bacopa seems to inhibit acetylcholinesterase and might increase acetylcholine levels, which could counteract the effects of anticholinergic drugs. Similarly, anticholinergic drugs might counteract the cholinergic effects of bacopa.
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.

This Enlon-Plus combo is interesting because it pairs two opposite-acting medicines. The atropine part is the anticholinergic piece, and that's the one bacopa could theoretically bump against. Bacopa may gently raise levels of acetylcholine, the very chemical messenger that atropine is trying to block. On paper, that tug-of-war could blunt each one's effect, so atropine might not control secretions or heart rate quite as well as expected.

I'd stress that this is theoretical, based on how these things work in the lab, not on real patient reports. Also, Enlon-Plus is usually a one-time hospital injection used during surgery, so a daily memory supplement rarely overlaps with it. Still, mention any supplements you take to your anesthesia team or pharmacist beforehand.

CHOLINERGIC DRUGS

2 of 2

Edrophonium, Atropine also falls under CHOLINERGIC DRUGS.

Theoretically, concurrent use of bacopa with other cholinergic drugs might have additive effects.
Bacopa seems to inhibit acetylcholinesterase and might increase acetylcholine levels. Theoretically, this could result in additive cholinergic effects when used with cholinergic drugs.
Severity Moderate Likelihood Possible Evidence D

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

Here's the basic idea. Bacopa may gently block an enzyme called acetylcholinesterase, which lets more acetylcholine (a nerve-signaling chemical) hang around in the body. Edrophonium does almost the same thing on purpose, so taking the two together could, in theory, push cholinergic effects too far in the same direction. That might look like watery eyes, drooling, a slow heartbeat, stomach cramps, or trouble breathing. The atropine portion of Enlon-Plus actually counters that, which complicates the picture.

Honestly, this combination is unusual since edrophonium is given by a clinician in a monitored setting, not at home. The concern here is theoretical, based on how bacopa behaves in lab studies, not real cases. Still, mention any bacopa use to your doctor or pharmacist beforehand.

From our pharmacist’s overview on the Edrophonium, Atropine page

“Enlon-Plus combines edrophonium, which raises levels of the nerve messenger acetylcholine, with atropine, which tempers its side effects, and the supplements listed below can tip that balance in either direction. I read this list with real caution.”

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.
