IDENTITY
HALF-LIFE
HOW IT IS THOUGHT TO WORK
Mazdutide is a dual glucagon and GLP-1 receptor agonist based on the oxyntomodulin scaffold, developed by Innovent with Eli Lilly. As with survodutide, the glucagon component is intended to add energy expenditure and direct hepatic effects to GLP-1-mediated appetite suppression.
PHARMACOKINETICS
Given once weekly by subcutaneous injection. A discrete half-life value is not curated here.
REVIEW
PUBLISHED PAIR RECORDS
with Semaglutide
Overlapping incretin-pathway activitySemaglutide and Mazdutide both act on incretin or amylin-family receptor pathways involved in glycaemic control, appetite and gastric emptying. Approved GLP-1 product labelling states that coadministration with another GLP-1 receptor agonist is not recommended, that these agents delay gastric emptying and may affect absorption of concomitantly administered oral medicines, and that combination with insulin or an insulin secretagogue increases hypoglycaemia risk. One member of this pair is an approved prescription product carrying that labelling; the other is investigational, so its combination data are incomplete. Peppy reports curated pharmacology, not a safety verdict. A prescriber or pharmacist should review any intended combination.

Reviewed 19 Aug 2026with MK-677
Opposing effects on glucose regulationMK-677 raises growth-hormone exposure, and growth hormone is a counter-regulatory hormone: controlled human studies show GH administration impairs insulin-stimulated glucose uptake and deteriorates glucose tolerance through increased lipolysis, with chronic GH excess producing insulin resistance. Mazdutide acts in the opposite direction on glycaemic control. Trials of the oral secretagogue MK-677 specifically report raised fasting glucose and impaired glucose tolerance. The combined effect on blood glucose is therefore not predictable from either agent alone and warrants monitoring rather than assumption. Peppy reports curated pharmacology, not a safety verdict.

Reviewed 19 Aug 2026with PT-141
Additive delay of gastric emptyingBremelanotide (PT-141) labelling states that it slows gastric emptying and may reduce the rate and extent of absorption of concomitantly administered oral medicines - patients are advised to avoid it alongside oral drugs that depend on threshold concentrations, and to avoid oral naltrexone products entirely because exposure is significantly decreased. Approved GLP-1 labelling carries the same gastric-emptying caution. Scheduling Mazdutide alongside PT-141 therefore stacks two agents that independently delay gastric emptying, which matters most for any oral medicine taken in the same window.

Reviewed 21 Aug 2026with Pramlintide
Labelled caution: two agents that slow gastric emptyingPramlintide labelling states that it slows gastric emptying, that it is not recommended for patients taking other drugs that alter gastrointestinal motility, and that concomitant oral medicines whose effect depends on a threshold concentration should be taken at least 1 hour before or 2 hours after injection. Mazdutide carries its own labelled statement that it delays gastric emptying and may affect the absorption of concomitantly administered oral medicines. This is therefore not an inference from shared mechanism - each product's own labelling describes the effect the other also produces. Pramlintide additionally carries a boxed warning for severe hypoglycaemia when used with insulin, and GLP-1 labelling records increased hypoglycaemia risk in combination with insulin or an insulin secretagogue.

Reviewed 21 Aug 2026with Teduglutide
Opposing effects on intestinal absorptionTeduglutide is a GLP-2 analogue that increases villus height and crypt depth, enlarging absorptive surface area; its labelling records a potential for increased absorption of concomitant oral medicines and advises monitoring where a drug is titrated or has a narrow therapeutic index, since the oral drug may need its dose reduced. Mazdutide works in the opposite direction on the same variable - incretin-pathway labelling and pharmacology describe delayed gastric emptying, which slows the rate at which an oral medicine reaches the small intestine. One agent is enlarging the absorptive surface while the other is changing the timing of delivery to it, so the net effect on any co-administered oral medicine is not predictable from either alone. The metabolic agent in this pair is investigational, so no labelled combination guidance exists for it. Peppy reports curated pharmacology, not a safety verdict.

Reviewed 25 Aug 2026HUMAN EVIDENCE
Approved by China's NMPA in June 2025 for obesity, with a parallel type 2 diabetes pathway - it is not approved by FDA or EMA, and the trials are predominantly in Chinese populations, which limits direct generalisation. GLORY-2 reported up to 20.1% weight loss at 9 mg, and in a liver-fat subgroup without type 2 diabetes and baseline liver fat of 10% or more, a mean MRI-PDFF change of -71.9% at week 60 against +5.1% for placebo. The head-to-head DREAMS-3 trial reported superior glycaemic control with weight loss against semaglutide. A phase 3 MASH programme is at an earlier stage than survodutide's.
REPORTED EFFECTS
Gastrointestinal adverse effects predominate, as across this class. Because approval is limited to China, there is no FDA- or EMA-reviewed adverse-reaction table, and the safety characterisation available in English is largely sponsor press releases and trial publications rather than regulator-verified labelling.
RESEARCH LIMITATIONS
The cited studies are time-limited and population-specific. They do not establish universal benefit, long-term safety, or an individual treatment plan.
