What is Acid Reflux

Gastroesophageal acid reflux disease (GERD) is a common chronic condition where acid formed in the stomach leaks through the esophageal sphincter. The acid then irritates or erodes the lining of the sphincter called the esophageal epithelium.1

Symptoms

People suffering from GERD may experience:

  • Burning sensation in the chest
  • Difficulty swallowing
  • Chest pain among

Acid Reflux
Symptoms

Burning sensation in the chest, difficulty swallowing, chest pain among others.

Therapeutic
Potential

Preclinical data suggests THC among cannabinoid receptors CB1 and CB2  may be therapeutic for Acid Reflux.

Application
options

Depending on your needs, the optimal type of application may vary. Find more information on our application options.

The connection between Cannabinoids & Acid Reflux

Studies find that CBD and THC may have great therapeutic potential and may be used to help treat Acid Reflux. CBD and THC are well-known cannabinoids, however, they do not have the same psychoactive effects. THC is psychoactive while CBD does not possess psychoactive effects. According to WHO guidelines, the cannabidiol CBD is generally well tolerated with a good safety profile.

Cannabinoid receptors can be found in both esophageal epithelial cells and neurons in the esophageal myenteric plexus, which may be involved in controlling esophageal function..

In addition, data have shown that THC plays a role in decreasing acid reflux.

However, further studies are needed to find out the full connection between the endocannabinoid system in gastro-esophageal function and the potential treatment of this disease with plant cannabinoids.2

The literature discussion is an overview of the published results from scientific studies investigating if and how cannabinoids can be beneficial in the treatment of Acid Reflux. The overview will be updated regularly to ensure the newest and most accurate information.

Cannabinoid receptors may be involved in Acid Reflux
CB1 receptors are expressed by human oesophageal epithelial cells and in Gastro-Esophageal Reflux Disease these receptors are downregulated.3/sup>

CB2 receptors are found in the digestive tract 4,however, they are not expressed in human esophageal epithelial cells3.


In a study with mice, it was shown that CB2 receptor agonists in a dose-dependent manner exhibit a protective effect against ethanol and diclofenac-induced gastric ulcers. CB2 antagonists reversed this effect.4

It was found that in the myenteric plexus of the esophagus human CB1 and CB2 receptors are expressed abundantly.5

In mice, gastric acidity and ulceration can be reduced by increasing ambient endocannabinoid levels through blocking MAGL.6

In dogs and human volunteers, the number of Transient Lower Esophageal Sphincter Relaxations was reduced by THC. CB1 antagonist SR141716A blocked this effect, proposing participation of CB1.7

Clinical trials are research studies that examine new treatments and evaluate their effects on human health outcomes.

Today, we are not able to provide any clinical trials about cannabinoids and Acid Reflux.
