Group 1: Mechanism and Efficacy - GIP plays a crucial role in insulin secretion, accounting for approximately 44% of insulin release after oral glucose intake, while GLP-1 contributes only 22% [5]. - Tirzepatide, modified from GIP, has a half-life of 5 days, allowing for weekly administration, and shows better efficacy in blood sugar control and weight loss compared to GLP-1 receptor agonists [7][8]. - Clinical trials indicate that Tirzepatide significantly reduces body weight in patients with obesity or prediabetes, with weight loss percentages of 15.4% (5mg), 19.9% (10mg), and 22.9% (15mg) compared to a mere 2.1% in the placebo group [10]. Group 2: Clinical Trials and Results - The SURMOUNT-2 study demonstrated that higher doses of Tirzepatide led to an average weight loss of 15.7% (15.6kg) in type 2 diabetes patients over 72 weeks, with 81.6% of patients in the 10mg group losing over 5% of their body weight [12]. - The SURMOUNT-3 trial showed a weight reduction of up to 26.6% after 12 weeks of lifestyle intervention and 72 weeks of Tirzepatide treatment [14]. - In the SURMOUNT-5 trial, patients treated with Tirzepatide lost an average of 22.8kg, outperforming the active control group by 47% in weight loss [14]. Group 3: Safety and Side Effects - Approximately 80% of Tirzepatide users reported at least one side effect, primarily gastrointestinal issues such as nausea and diarrhea, similar to those experienced with Semaglutide [15]. - The incidence of nausea was reported at 33% for the highest dose of Tirzepatide, compared to 44% for Semaglutide, indicating a potentially lower side effect profile for Tirzepatide [15][17]. - GIP's role in appetite suppression may help mitigate some of the adverse effects associated with GLP-1 receptor activation, enhancing patient compliance and treatment efficacy [19].
