Market Dynamics and Patent Landscape for ATC Class A08A — Ant obesity preparations, excluding diet products
Executive Summary
The ATC (Anatomical Therapeutic Chemical) classification system categorizes drugs used in medical treatments. Class A08A specifically targets anti-obesity preparations excluding diet products, encompassing pharmacological agents designed to promote weight loss or manage obesity-related health risks. As of 2023, global obesity prevalence has surged to approximately 19%, propelling the pharmaceutical market focusing on anti-obesity drugs to an estimated $4.8 billion by the end of 2025, with a compound annual growth rate (CAGR) of approximately 7%.
The market landscape reveals a shift toward novel pharmacotherapies targeting central appetite regulation, gut hormones, and metabolic pathways. Major pharmaceutical players such as Novo Nordisk, Eli Lilly, and Roche are investing heavily in innovative therapeutics, with recent approvals like Wegovy (semaglutide) and Mounjaro (tirzepatide) transforming treatment paradigms.
The patent landscape is characterized by intense competition, with key patents protecting active ingredients, delivery systems, and combination therapies. Patent expirations and challenges continue to shape the innovation pipeline, incentivizing R&D in this domain.
