While Zepbound and Mounjaro are not identical, they share tirzepatide as their active ingredient. Zepbound, specifically approved for combating obesity involves mimicking two hormones, GLP-1 and GIP, to curb appetite and optimize the body's processing of fat and sugar.   Through its dual mechanism of action, tirzepatide both slows the emptying of food from the body helping patients remain full for longer, and tells the patient’s brain they are full by mimicking hormones to cut down on cravings.   Mounjaro, though sharing the same active ingredient, is only FDA-approved for diabetes management capabilities. However, its off-label use in weight management indicates its versatility and efficacy.
