Core Viewpoint - Tirzepatide is a drug that has gained attention in diabetes treatment and weight management, mimicking the action of the natural GLP-1 hormone to regulate blood sugar levels, promote insulin secretion, suppress appetite, and delay gastric emptying [4][10]. Mechanism of Action and Clinical Advantages - Tirzepatide activates GIP/GLP-1 receptors, promoting insulin secretion when blood sugar rises, reducing glucagon release, delaying gastric emptying, and suppressing appetite, making it advantageous for treating type 2 diabetes and obesity [6][7][8][9][10]. Main Indications - Type 2 Diabetes Patients: Suitable for adults with poorly controlled blood sugar despite diet and exercise, especially those who are overweight or obese, as 67.7% of diabetes patients in China are overweight/obese [11][12]. - Obesity Patients: Effective for adults with a BMI ≥28 kg/m² or ≥24 kg/m² with at least one weight-related comorbidity [13][20]. Contraindications and Precautions - Not suitable for type 1 diabetes patients, those with diabetic ketoacidosis, severe gastrointestinal diseases, history of medullary thyroid carcinoma, pregnant or breastfeeding women, and patients with hypersensitivity [14][15][16][17]. Patient Characteristics Suitable for Tirzepatide - Weight Management Needs: Patients with a BMI ≥28 kg/m² or ≥24 kg/m² with comorbidities [20]. - Blood Sugar Control Needs: Patients with poorly controlled blood sugar on other medications [21]. - Simplified Treatment Needs: Patients preferring less frequent dosing [22][23]. - Low Hypoglycemia Risk: Suitable for elderly patients and those in high-risk occupations [24][25]. Adverse Reactions and Management Strategies - Common adverse reactions include gastrointestinal issues (nausea, vomiting, diarrhea) and injection site reactions [27][28]. Management strategies involve gradual dose escalation and dietary adjustments [30][31]. Combination Use with Other Medications - With SGLT-2 Inhibitors: Can improve blood sugar control and weight loss [33]. - With Insulin: Can reduce insulin dosage and mitigate weight gain associated with insulin [34][35]. Future Development Directions - Oral Formulations: Development of oral tirzepatide formulations to enhance patient options [36][37]. - Applications in Specific Patient Populations: Research on its use in obese patients with heart failure and obstructive sleep apnea [38][40]. - Personalized Treatment: Potential for genetic testing to identify suitable patients for tirzepatide [41][42]. Efficacy - Clinical studies show that tirzepatide can reduce HbA1c by an average of 2.37% and lead to an average weight loss of 10.3 kg in type 2 diabetes patients [43]. It is the first drug to achieve over 20% weight loss in obese patients in phase 3 trials [43]. Conclusion - Tirzepatide offers multiple metabolic benefits for treating type 2 diabetes and obesity, suitable for patients needing blood sugar and weight control, with attention to contraindications and personalized treatment [44].
