Study Reveals Tirzepatide's Efficacy in Weight Loss for Non-Diabetic Adults
A recent study has demonstrated the effectiveness of tirzepatide, a dual GIP/GLP-1 receptor agonist, in promoting weight loss among adults with obesity who do not have diabetes. Conducted as a prospective multicentre observational study, 115 participants were administered tirzepatide at a starting dose of 2.5 mg weekly for four weeks, which was then increased to 5 mg for a total of 12 weeks. The study observed significant reductions in body weight, with an average decrease of 8.2 kg, equating to a 7.3% reduction in body mass index (BMI). Additionally, 46.1% of participants achieved a weight loss of 5% or more. The study also noted improvements in metabolic parameters, including reductions in HbA1c, LDL cholesterol, and triglycerides. However, HDL cholesterol and eGFR levels remained unchanged. Nausea was reported as the most common adverse event, affecting 7.8% of participants, and 10.4% discontinued treatment, primarily those with prior GLP-1 receptor agonist use.
