How Rimonabant works
Rimonabant is a selective cannabinoid-1 (CB1) receptor antagonist. It works by selectively blocking the CB1 receptors found in the body's endocannabinoid system, specifically in areas like the brain, fat tissue, liver, muscles, and digestive tract. By blocking these receptors, Rimonabant helps to decrease appetite, increase the feeling of fullness after eating (satiety), and improve the regulation of metabolism.
