World Health Organization Updates Model Lists of Essential Medicines

The World Health Organization (WHO), at its 25th Expert Committee meeting , updated the Model Lists of Essential Medicines (EML).

About the Update

  • Drugs Added: Semaglutide, dulaglutide, liraglutide, and tirzepatide, all GLP-1 receptor agonists were included in the EML.

About Glucagon-Like Peptide-1 (GLP-1) Receptor 

  • GLP-1 agonists are a class of medicines used primarily to control blood sugar levels in people with Type 2 diabetes, and some are also effective in treating obesity.
  • They are usually administered as subcutaneous injections, where the drug is injected into the fatty tissue just under the skin.

  • Indications: These drugs are used as glucose-lowering therapy for adults with type 2 diabetes mellitus, cardiovascular disease, chronic kidney disease, and obesity.
  • Scientific Rationale: Evidence showed their effectiveness in controlling glucose, reducing weight, and improving cardio-metabolic health.

Global Health Challenge

  • Diabetes Burden: Over 800 million people worldwide live with diabetes; half go untreated (WHO, 2022).
  • Obesity Burden: More than one billion people globally suffer from obesity, with rising rates in low- and middle-income countries.
  • Urgency: WHO cited diabetes and obesity as two of the most urgent health challenges of the present era.

Diabetes in India

  • India has an estimated 77 million adults (aged 18 and above) living with Type 2 diabetes, making it one of the largest diabetic populations in the world.
  • In addition, nearly 25 million people are pre-diabetic, meaning they are at higher risk of developing diabetes in the near future.

Diabetes

  • Diabetes is a chronic metabolic disease marked by persistently high blood glucose levels, which over time can damage the heart, kidneys, eyes, nerves, and blood vessels.
  • Type 2 diabetes (most common) results from insulin resistance or insufficient insulin, while Type 1 diabetes is caused by the pancreas producing little or no insulin; 

Obesity

  • Obesity is a medical condition in which excess body fat accumulates to the extent that it may harm health, typically defined as a Body Mass Index (BMI) of 30 or higher in adults.
  • It is a major risk factor for non-communicable diseases such as diabetes, cardiovascular diseases, certain cancers, and musculoskeletal disorders.

WHO’s Essential Medicines List (EML)

  • Establishment: First published by the World Health Organization (WHO) in 1977 with 208 medicines.
    • It is updated every two years by the WHO Expert Committee on Selection and Use of Essential Medicines.
  • Objective: To ensure that all people have access to the most important medicines needed for addressing priority healthcare needs.
  • Purpose
    • Serves as a guideline for countries to prepare their own national essential medicine lists.
    • Promotes equitable access, affordability, and rational use of medicines.
    • Supports governments in procurement, supply chain management, and health policy planning.
  • Criteria for Inclusion
    • Public Health Relevance: The medicine must address a significant health need.
    • Efficacy and Safety: Supported by reliable evidence of effectiveness and acceptable risk profile.
    • Cost-effectiveness: Provides the best health outcomes relative to available resources.
  • India’s Context: India has its own National List of Essential Medicines (NLEM), aligned with the WHO EML, to prioritise procurement and regulate drug prices.
