Is tirzepatide the same as Zepbound?
Yes. Zepbound is a brand name for tirzepatide, the same drug that switches on both the GIP and GLP-1 receptors and is sold as Mounjaro for other uses. This site's tirzepatide profile lists both names as other names. Zepbound is the FDA approved brand for long-term weight management and for obstructive sleep apnea in people with obesity. That is based on SURMOUNT-1 (2,539 adults, up to 20.9% average weight loss at 72 weeks on 15 milligrams, versus 3.1% on a dummy shot) and SURMOUNT-OSA (breathing pauses during sleep down by about 25 per hour at 52 weeks). The molecule is the same. The approved use and the pen you are handed are what differ.
