Tirzepatide

Mounjaro
Management of type 2 diabetes

Treatment of obesity and overweight conditions

Potential application in reducing cardiovascular risk factors

Tirzepatide is a synthetic peptide that functions as a dual agonist for glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. It is approved for the treatment of type 2 diabetes and obesity, marketed under the brand names Mounjaro and Zepbound, respectively.

Mechanism of action

Tirzepatide binds to GIP and GLP-1 receptors, enhancing insulin secretion, suppressing glucagon release, delaying gastric emptying, and promoting satiety. These combined actions lead to improved glycemic control and weight reduction. Its molecular modifications extend its half-life to approximately five days, allowing for once-weekly dosing. 

Notable Studies

The SURPASS clinical trials demonstrated significant reductions in HbA1c and body weight in patients with type 2 diabetes treated with Tirzepatide. 

The SURMOUNT-1 trial showed that Tirzepatide led to substantial weight loss in obese individuals without diabetes. 

Risk Associated

Common side effects include nausea, vomiting, diarrhea, constipation, and abdominal discomfort. There is a potential risk of thyroid C-cell tumors, as observed in rodent studies; however, the relevance to humans is unknown. Tirzepatide is contraindicated in individuals with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2. 

Dosage

For type 2 diabetes: Initiate at 2.5 mg subcutaneously once weekly for 4 weeks, then increase to 5 mg once weekly. The dose may be increased in 2.5 mg increments after at least 4 weeks at the current dose, up to a maximum of 15 mg once weekly.
