HelixTalk - Rosalind Franklin University's College of Pharmacy Podcast

In this episode, we will discuss mechanism, pharmacokinetics, efficacy, safety, and possible place in therapy for tirzepatide (Mounjaro), a new treatment for type 2 diabetes.

Key Concepts

  1. Tirzepatide is a novel GIP and GLP-1 receptor agonist resulting in glucose-dependent secretion of insulin and a decrease in glucagon secretion.
  2. This medication was FDA approved in May 2022 for the treatment of type 2 diabetes as an adjunct to diet and exercise. It is available as a long-acting once weekly pen injection to be administered subcutaneously.
  3. Current efficacy data exist from a 40-week trial which showed that tirzepatide was superior to semaglutide in A1c reduction and weight loss.
  4. The most common adverse effects of tirzepatide include GI concerns such as nausea, vomiting, and diarrhea as well as hypoglycemia.
