The endocannabinoid (EC) system is a physiological system with an important regulatory role in numerous biological functions, both centrally and peripherally. In certain conditions it can become hyperactive and induce a variety of disorders. The system has two receptor types, designated CB1 and CB2 (present respectively in the CNS and the periphery), as well as endogenous ligands (AEA and 2-AG) and equipment for transporting, synthesizing and degrading them. The discovery of specific CB1 antagonists has opened up interesting new possibilities for the treatment of obesity, diabetes and cardiometabolic risk factors.

This narrative review explores the benefits and risks of cannabinoids in kidney health, particularly in individuals with pre-existing renal conditions. It discusses the roles of cannabinoid receptor ligands (phytocannabinoids, synthetic cannabinoids, and endocannabinoids) in kidney physiology. The metabolism and excretion of these substances are also highlighted, with partial elimination occurring via the kidneys.

An impact of legalization and decriminalization of marijuana is the gradual increase in the use of cannabis for recreational purposes, which poses a potential threat to society and healthcare systems worldwide. However, the discovery of receptor subtypes, endogenous endocannabinoids, and enzymes involved in synthesis and degradation, as well as pharmacological characterization of receptors, has led to exploration of the use of cannabis in multiple peripheral and central pathological conditions. The role of cannabis in the modulation of crucial events involving perturbed physiological functions and disease progression, including apoptosis, inflammation, oxidative stress, perturbed mitochondrial function, and the impaired immune system, indicates medicinal values.

Cisplatin, a chemotherapeutic drug, is known for causing gastrointestinal disorders and neuropathic pain, but its impact on visceral sensitivity is unclear. Monosodium glutamate (MSG) has been shown to improve gastrointestinal dysmotility and neuropathic pain induced by cisplatin in rats. This study aimed to determine if repeated cisplatin treatment alters visceral sensitivity and whether dietary MSG can prevent these changes.

Neuropathy is the most common complication of diabetes, leading to painful symptoms like hyperalgesia. Current treatments for diabetic painful neuropathy often prove inadequate, necessitating the exploration of new pharmacological approaches. Therefore, this study aimed to investigate the potential antinociceptive effect of aspirin-triggered lipoxin A4 (ATL), a specialized pro-resolving lipid mediator, when administered alone or in combination with cannabinoid agonists, to alleviate diabetic neuropathic pain.
