Introduction . Semaglutide preparations are an important therapeutic option for patients suffering from type 2 diabetes mellitus and obesity due to their high efficacy the expected increase in prevalence of these diseases. Consequently, there is a growing need development domestic analogs semaglutide requiring bioequivalence studies. This study proposes use high-performance liquid chromatography with tandem mass spectrometry (HPLC-MS/MS) as alternative widely used immunoassay quantitative determination human serum.

Obesity is a complex and growing global concern, affecting one in eight individuals compromising health, quality of life expectancy. It carries significant metabolic, cardiovascular, oncological, hepatorenal, skeletal psychiatric risks, imposing substantial costs on health‐care systems. Traditional treatments have often been ineffective or led to relapse after lifestyle changes. Whereas bariatric surgery effective, it also involves risks such as mortality hospitalisation. Semaglutide, licensed 2018, synthetic analogue glucagon‐like peptide 1 which regulates glucose metabolism gastrointestinal (GI) motility. Studies show that semaglutide, administered either weekly subcutaneously, daily orally, induces an average weight loss −11.62 kg compared placebo reduces waist circumference by up −9.4 cm. improves blood pressure, fasting levels, C‐reactive protein levels lipid profiles. The most common adverse events are mild‐to‐moderate GI complaints occurring more frequently with administration than doses; hypoglycaemia without intervention. Weight regain follows semaglutide withdrawal. Furthermore, offers cardiovascular benefits for patients established atherosclerotic disease (CVD), lowers the risk kidney outcomes cardiovascular‐related death, resolves nonalcoholic steatohepatitis many cases, positively impacts mental health life. In conclusion, therapy could significantly benefit adults regarding CVD if made widely accessible. Ethical financial considerations must be addressed personalised obesity treatment approaches.

This review addresses the role of semaglutide (SMG), a GLP-1 receptor agonist, in treatment obesity and its related comorbidities. Originally developed for type 2 diabetes (DM2), SMG has shown significant efficacy weight reduction, with superior results compared to other treatments same class. Its effects include appetite suppression, increased satiety, improvements cardiovascular, renal, metabolic parameters. Studies such as SUSTAIN, PIONEER, STEP highlight superiority agonists anti-obesity drugs. The oral formulation showed promising initial results, higher doses (50 mg) showing losses comparable those subcutaneous administration. Despite benefits, there are challenges, regain after cessation treatment, gastrointestinal adverse effects, variability response. Future studies should explore strategies mitigate these identify predictive factors efficacy, expand therapeutic indications conditions insulin resistance. constant innovation this class drugs reinforces potential transform protocols chronic weight-related diseases.
