    • The active ingredient, semaglutide, was later noted for causing weight loss, which led to its off-label use for treating obesity.
    • This usage became popular on social media, influencing further developments.

    What is Tirzepatide?

    • Tirzepatide is the main component of Eli Lilly’s drugs, Mounjaro and Zepbound.
    • It’s important to note here that Mounjaro is the brand name for diabetes, while Zepbound is for weight loss.

    How does it work?

    There is a dual action involving two hormones:

    (1) Regulation of glucagon-like peptide-1 (GLP-1): 

    • GLP-1 is a hormone that regulates appetite and calorie intake through effects on the brain and digestive tract.
    • Both semaglutide and tirzepatide function as polypeptides that enhance the body’s levels of GLP-1.
    • The higher levels of GLP-1 trigger satiety, the feeling of fullness, reducing the desire to eat.

    (2) Regulation of Glucose-dependent Insulinotropic polypeptide (GIP):

    • Unlike semaglutide, tripeptide also increases levels of GIP, the other hormone involved.

    Promising Global Trials

    • Global clinical trials for tirzepatide (Zepbound) have shown significant results, with the highest dosage leading to an average weight loss of 20.9% over 72 weeks.
    • The approval in India is due on further post-marketing surveillance (Phase IV trials) to monitor the drug’s side effects and its effectiveness across India’s diverse population.

    Long-term side effects:

    • Cardiovascular risks like increased heart rate and potential blood pressure elevation.
    • Gastrointestinal effects include nausea, vomiting, diarrhoea, and constipation. Endocrine concerns involve thyroid C-cell tumours in MEN syndrome patients.
    • Other issues include kidney problems, eye complications, mental health impacts, and long-term risks like pancreatic enzyme elevation and gallbladder problems.

    Why under-consideration in India?

    • India has the world’s second-highest number of people with type 2 diabetes and high obesity rates.
    • A study in Lancet in 2023 estimated that 101 million people in India — 11.4 per cent of the country’s population — are living with diabetes.
    • As per the World Obesity Federation Atlas, around 11 per cent of Indian adults will be obese by 2034.
