Cannabigerol (cbg) and Pargyline

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Pargyline

Pargyline falls under ANTIHYPERTENSIVE DRUGS — the group Cannabigerol (cbg) interacts with.

Theoretically, taking cannabigerol with antihypertensive drugs might increase the risk of hypotension.
Animal research shows that an intraperitoneal injection of cannabigerol lowers blood pressure. The mechanism of action may be related to alpha-2-adrenoreceptor activity. The effect of oral intake of cannabigerol is unclear and this has not been shown in humans.
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 explains PharmD, Clinical Pharmacist

Here's the situation with pargyline (Eutonyl), which is an older blood pressure medicine that works as a monoamine oxidase inhibitor. The concern here is simple: both pargyline and CBG can push your blood pressure downward. Stack them together and you might lower it more than you want.

In plain terms, if your pressure drops too far you could feel dizzy, lightheaded, or faint, especially when you stand up quickly. I want to be honest about how strong this evidence is, though. It's theoretical and based only on animal research where CBG was injected, not taken by mouth. We simply don't have human studies showing this happens with oral CBG. Still, since pargyline is a potent older drug, it's worth a quick chat with your pharmacist or doctor before combining them.

About Cannabigerol (cbg)

What is Cannabigerol (cbg)?

  • Anxiety and stress
  • Pain and inflammation
  • Sleep support
  • Focus and mood
  • Digestive discomfort

Cannabigerol (CBG) is a minor cannabinoid from the cannabis (hemp) plant that is marketed for anxiety, pain, and inflammation, but human research is very limited and most claims rest on laboratory and animal studies. It appears to be generally well tolerated in early reports, but its long-term safety, quality, and dosing are not well established. Talk to your pharmacist or doctor before trying it, especially if you take other medicines or are pregnant or breastfeeding.
