Dulaglutide

Trulicity

0.75mg – 0.75 mg SubQ weekly
Antidiabetic

Dulaglutide (brand name Trulicity) is a long-acting glucagon-like peptide-1 receptor agonist (GLP-1 RA) developed by Eli Lilly for the treatment of type 2 diabetes mellitus. It consists of a GLP-1 analog covalently linked to a modified human IgG4 Fc fragment, which extends its half-life to approximately 5 days, allowing once-weekly subcutaneous dosing. It was FDA-approved in 2014.

How it works

Activates the GLP-1 receptor on pancreatic beta cells, stimulating glucose-dependent insulin secretion (incretin effect) while suppressing inappropriate glucagon release from alpha cells.

Slows gastric emptying, reducing the rate of glucose absorption from the gut and contributing to postprandial glucose control and increased satiety.

Centrally acts on hypothalamic appetite centers to reduce food intake. May also have direct cardioprotective effects including reduced inflammation, improved endothelial function, and decreased atherosclerosis progression.

Each reference below was re-fetched from its PubMed record, and the quoted sentence was confirmed to appear in that abstract and to support the claim it sits under. Follow any of them to read the source.

Adults with type 2 diabetes received dulaglutide 0.75 mg by subcutaneous injection once weekly for 24 weeks.

Eligible adult patients (≥18 years) with inadequately controlled type 2 diabetes (HbA1c concentration ≥7·0% [53 mmol/mol] and ≤9·5% [80 mmol/mol]), a BMI of 45 kg/m2 or less, and taking stable doses (>3 months) of an SGLT2 inhibitor (with or without metformin) were randomly assigned (1:1:1) via an interactive web-response system to subcutaneous injections of either dulaglutide 1·5 mg, dulaglutide 0·75 mg, or placebo once per week for 24 weeks.

Evidence scope. AWARD program review; supports receptor class, not every detailed downstream mechanism on the page.

GI adverse events were more common with dulaglutide, including nausea, diarrhea, and vomiting at 0.75 and 1.5 mg weekly.

Treatment-emergent adverse events were more common in patients treated with dulaglutide than in patients who received placebo, mainly because of an increased incidence of gastrointestinal adverse events.

Evidence scope. Human 24-week add-on trial; adverse-event rates are population and concomitant-therapy specific.

Claims we could not support

No abstract we checked supports these for this molecule at this route. That is not the same as saying they are false — it marks where the evidence is missing.

Detailed mechanism: glucose-dependent insulin secretion, glucagon suppression, gastric slowing, and central appetite action. The selected exact-drug review establishes GLP-1 receptor agonism but not this entire bundle in one matched sentence.

Oral-contraceptive backup warning shown on the page. The page text itself attributes this warning to tirzepatide; no checked dulaglutide source supports transferring it.
