On November 8, 2023, Ozempic, Wegovy, and Mounjaro bought firm when the Meals & Drug Administration permitted Zepbound for people who’re residing with weight problems or are obese with not less than one weight-related situation.

Zepbound is the most recent in a category of medicine that may assist sufferers lose vital weight, becoming a member of Ozempic, Wegovy, and Mounjaro.

Whereas Zepbound and Mounjaro share the identical generic drug identify, tirzepatide, and are each produced by Eli Lilly, Mounjaro, is just FDA permitted for sufferers with sort 2 diabetes.

Nonetheless, Ozempic, like Mounjaro, is just for sufferers with sort 2 diabetes, whereas Wegovy will also be prescribed for the remedy of weight problems and obese with particular situations. The medication have made headlines, been referenced in fashionable tradition, and change into extremely popular.

One physician says there’s an excellent motive for the curiosity.

“They work,” says Dr. Dina Peralta-Reich, MD, FAAP, FOMA, the director of New York Weight Wellness Medication. “Lastly, we’ve got protected and extremely efficient drugs obtainable available on the market for managing obese and weight problems.”

Nonetheless, the excitement can create confusion and misinformation. Consultants share that it’s important for sufferers to know the info to handle expectations, make knowledgeable choices about their healthcare, and make optimistic modifications to succeed in well being and weight reduction targets.

“Lots of the weight reduction drugs have contraindications and numerous unwanted effects, emphasizing the necessity for shut medical supervision,” says Dr. Jihad Kudsi, MD, ABOM, MBA, MSF, FACS, an weight problems medication specialist and bariatric surgeon. “Moreover, not embracing more healthy habits like a balanced weight-reduction plan and common train can pose challenges for reaching lasting weight reduction.”

To assist, suppliers answered ceaselessly requested questions on Zepbound.

Zepbound, or Tirzepatide, is an injectable medicine permitted by the FDA for the remedy of weight problems and obese with some situations.

“It’s a mixture of two incretins, GLP-1, or Glucagon-like peptide-1, and GIP, or Gastric inhibitory polypeptide,” Peralta-Reich says.

Per the FDA approval, people are eligible for Zepbound in the event that they:

  • Have a physique mass index (BMI) of 30 kilograms per sq. meter (kg/m2) or extra (weight problems)
  • Have a BMI of 27 kg/m2 or higher (obese) with a minimal of 1 weight-related situation, like hypertension, sort 2 diabetes, or excessive ldl cholesterol

“The medicine is a weekly injection sufferers administer at residence,” provides Matthew Tucker, PA-C, of Novant Well being Salem Surgical Weight Loss. “The beginning dose is 2.5mg weekly, and the dose will be elevated month-to-month at intervals of two.5mg as much as a most dose of 15mg weekly. The upkeep dosages shall be 5mg, 10mg, and 15mg.”

In a 2022-published trial of greater than 2,500 adults, contributors noticed a mean weight discount of 15%, with sufferers lowering physique weight by as much as 22.5%. One other current trial indicated a mean weight lack of 26%.

One knowledgeable says the outcomes are promising, however cautions sufferers ought to handle expectations.

“There’s no one-size-fits-all remedy for weight problems,” says Dr. Katherine H. Saunders, MD, DABOM, the co-founder of Intellihealth and an Weight problems Medication doctor at Weill Cornell Medication. “Some people shall be extraordinarily profitable with Zepbound whereas others may not lose a lot weight in any respect.”

Zepbound prompts two hormone receptors, GIP (glucose-dependent insulinotropic polypeptide or gastric inhibitory polypeptide) and GLP-1 (glucagon-like peptide-1).

“Tirzepatide is a medicine that imitates the actions of pure GIP and the GIP receptor,” Peralta-Reich says. “When mixed with the GLP-1 receptor, it helps with insulin secretion and regulates glucose and lipid metabolism.”

Peralta-Reich explains that these hormones are secreted by the cells within the gut. “After an individual eats, these hormones are secreted by the cells within the intestines and begin working.”

“In addition they decelerate gastric emptying, which makes the particular person really feel full for an extended interval,” Peralta-Reich says. “This finally results in weight reduction for people who battle with power weight problems.”

If the phrase “tirzepatide” sounds acquainted, that’s as a result of it’s also the medicine branded as Mounjaro, each of that are made by Eli Lilly.

How do they differ? Little or no.

“They’re the identical medicine,” Peralta-Reich says. “The one distinction is that Zepbound is FDA-approved for obese with comorbidities and weight problems, and Mounjaro has been permitted for diabetes.”

Ozempic and Wegovy are model names for the drug semaglutide.

“In comparison with the opposite GLP-1 receptor agonists like Wegovy, Zepbound is a twin agonist,” says Saunders. “It targets each GLP-1 and GIP versus Wegovy, which simply targets GLP-1.”

Saunders says sufferers might report fewer unwanted effects like GI discomfort from taking Tirzepatide versus Ozempic or Wegovy.

Although headlines lately pointed to a non-peer-reviewed examine that indicated that sufferers taking tirzepatide misplaced extra weight than these taking semaglutide, Tucker says it’s too quickly to inform.

“There have been no direct head-to-head, peer-reviewed research evaluating the drugs,” Tucker says.

Nonetheless, within the SURMOUNT-3 and SURMOUNT-4 trials, sufferers misplaced extra utilizing tirzepatide than contributors in a trial for semaglutide— 26.7% versus 15%. Nonetheless, the trials for semaglutide have been shorter (68 weeks) than for tirzepatide (84 weeks).

Like semaglutide, tirzepatide isn’t a fast, short-term repair.

“Anti-obesity drugs like Zepbound usually are not meant for short-term weight reduction, however reasonably long-term remedy of weight problems, which is a power illness,” Saunders says. Tirzepatide is supposed for long-term use.

An Eli Lilly trial of greater than 780 adults with weight problems or who have been obese however didn’t have diabetes noticed extra vital weight reduction in the event that they took Zepbound for 88 weeks than those that stopped after 36 weeks.

Those that switched to the placebo regained some weight, although they nonetheless maintained a 9.5% weight reduction.

Usually, sure. Nonetheless, Kudsi emphasizes that sufferers ought to concentrate on unwanted effects and contraindications. He says the most typical ones are GI-related and embody:

  • Nausea
  • Diarrhea
  • Vomiting
  • Constipation
  • Abdomen (stomach) ache
  • Indigestion

Kudsi provides that individuals might expertise elevated lethargy, injection-site reactions, and hair loss.

Extra extreme unwanted effects might embody:

Sufferers who’ve a well-known historical past of medullary thyroid carcinoma (MTC) or a historical past of A number of Endocrine Neoplasia syndrome sort 2 (MEN 2) are suggested to not take the drug due to the possibility it might trigger thyroid tumors.

About $1,060, Saunders says. However how a lot of {that a} affected person has to pay will range.

“The associated fee can range broadly relying on insurance coverage protection,” Tucker says. “Sufferers must examine with their insurance coverage suppliers to seek out out if Zepbound is roofed by their plan.”

Sufferers have had difficulties getting protection for anti-obesity medicine Wegovy, with some plans even lately lowering protection. Saunders hopes she’s flawed however predicts an identical subject with Zepbound.

“It’s my understanding that plans usually cowl or don’t cowl the entire class of anti-obesity drugs, with quite a lot of guidelines and restrictions, so I anticipate that plans at present overlaying Wegovy will increase their anti-obesity medicine armamentarium to incorporate Zepbound as effectively,” Saunders says.

Zepbound confirmed super promise in trials. Nonetheless, sufferers within the trials additionally underwent way of life modifications. Kudsi believes others taking Zepbound will see the perfect leads to shedding and sustaining weight in the event that they undertake related habits.

“A wholesome way of life together with wholesome balanced weight-reduction plan and exercising is important as a part of an entire weight problems remedy,” Kudsi says.

These modifications embody:

  • Logging 150 minutes of moderate-intensity cardio train weekly, akin to biking or brisk strolling
  • Power coaching not less than twice per week
  • Consuming a balanced weight-reduction plan filled with lean proteins and leafy greens

“Way of life modifications play a vital position in total well being, and relying solely on medicine with out addressing underlying way of life components can restrict the medicine’s effectiveness,” Kudsi says.

Zepbound, a model identify for tirzepatide, was permitted by the FDA for weight reduction in November.

It’s a dual-agonist drug that prompts GIP (glucose-dependent insulinotropic polypeptide or gastric inhibitory polypeptide) and GLP-1 (glucagon-like peptide-1) hormone receptors, aiding in glucose administration and serving to sufferers really feel fuller longer.

Numbers in trials range. In later trials, sufferers misplaced a mean of 26% physique weight throughout 88 weeks, a better share than sufferers taking semaglutide.

Zepbound might have fewer unwanted effects, like GI discomfort, however sufferers might expertise them.

Consultants additionally say that way of life modifications like weight-reduction plan and train may also help sufferers lose and keep weight extra successfully than Zepbound alone.
