Inhibitory Effect of Standardized Cannabis sativa Extract and Its Ingredient Cannabidiol on Rat and Human Bladder Contractility

Our data have suggested that CBD BDS reduces cholinergic-mediated contractility and that this effect is modulated by transient receptor potential vanilloid type-1 in rats but not in humans. CBD is the chemical ingredient of CBD BDS responsible for such activity. If confirmed in vivo, such results could provide a pharmacologic basis to explain, at least in part, the efficacy of Cannabis medicines in reducing incontinence episodes in patients with multiple sclerosis.
