Weight loss efficiency and safety of tirzepatide: A Systematic review.

Lin F, Yu B, Ling B, Lv G, Shang H, Zhao X, Jie X, Chen J, Li Y. Weight loss efficiency and safety of tirzepatide: A Systematic review. PLoS One. 2023 May 4;18(5):e0285197. doi: 10.1371/journal.pone.0285197. PMID: 37141329; PMCID: PMC10159347.

 

Highlights:

  • A review and meta-analysis of the scientific literature, involving a total of 3,613 individuals with obesity without diabetes, split into a treatment group receiving Semaglutide and a placebo group
  • The group that received Semaglutide showed a weight reduction of 11.85% over the placebo group.
  • However, the Semaglutide group showed that gastrointestinal adverse events were more 1.59 times more likely compared to placebo.

 

Result:

In total, ten studies (12 reports) involving 9,873 patients were identified. A significant loss body weight in the tirzepatide group versus the placebo by -9.81 kg (95% CI (-12.09, -7.52), GLP-1 RAs by -1.05 kg (95% CI (-1.48, -0.63), and insulin by -1.93 kg (95% CI (-2.81, -1.05), respectively. In sub-analysis, the body weight of patients was significantly reduced in three tirzepatide doses (5 mg, 10 mg, and 15 mg) when compared with those of the placebo/GLP-1 RA/insulin. In terms of safety, the incidence of any adverse events and adverse events leading to study drug discontinuation was higher in the tirzepatide group, but the incidence of serious adverse events and hypoglycaemia was lower. Additionally, the gastrointestinal adverse events (including diarrhea, nausea, vomiting and decreased appetite) of tirzepatide were higher than those of placebo/basal insulin, but similar to GLP-1 RAs.

 

Conclusion:

In conclusion, tirzeptide can significantly reduce the weight of T2DM and patient with obesity, and it is a potential therapeutic regimen for weight-loss, but we need to be vigilant about its gastrointestinal reaction.
