This upward shift in spending also enables governments and institutions to allocate more resources toward the development of novel antibiotic formulations and the establishment of effective distribution networks. Therefore, as healthcare systems expand and modernize, particularly in middle-income regions, the growing expenditure catalyzes increased antibiotic usage and deeper market penetration.
Growing Geriatric Population: The growing geriatric population is driving the use of antibiotics, primarily due to the increased susceptibility of older adults to bacterial infections. In 2024, the World Health Organization reported that the global population aged 60 and above is projected to rise from 1.1 billion in 2023 to 1.4 billion by 2030, indicating a substantial demographic shift toward aging. Elderly individuals become more prone to conditions such as pneumonia, urinary tract infections (UTI), and skin infections, which often require antibiotic treatment as the immune system weakens with age. Additionally, the prevalence of chronic illnesses in aging populations further elevates the risk of secondary infections, thereby increasing the need for consistent and effective antibiotic therapies.
Advancements in Research and Development: Advancements in research and development are driving the market expansion by addressing the rising challenge of antimicrobial resistance and introducing more effective treatment options. Innovations in drug discovery technologies, including genomics, synthetic biology, and AI-assisted screening, have enabled the development of novel antibiotics with improved efficacy and safety profiles. In March 2024, Stanford researchers developed SyntheMol, a generative AI model that designs novel antibiotic compounds and synthesis recipes. It produced six potential drugs targeting drug-resistant Acinetobacter baumannii, a critical WHO-priority pathogen. These R&D efforts are expanding the range of available antibiotic classes and also enhancing the precision with which bacterial pathogens are targeted. As a result, continued investments in research are propelling growth by providing advanced antibiotic solutions that meet evolving clinical needs.
The antibiotics market is witnessing active innovation, with several promising prospects in development aimed at combating multidrug-resistant pathogens. Continued efforts in antibiotic R&D are focused on introducing novel mechanisms of action to overcome resistance and broaden therapeutic efficacy. For instance, in June 2025, Roche, in collaboration with Harvard University, advanced its antibiotic candidate zosurabalpin into Phase 3 trials, targeting carbapenem-resistant Acinetobacter baumannii (CRAB), a critical Gram-negative pathogen. Additionally, in March 2025, Wockhardt filed ZAYNICH (zidebactam/cefepime) for approval in India after Phase III trials showed a 96.8% clinical cure rate for cUTI. Superior to meropenem (89% vs. 68.4%), US filing planned by August 2025.
