The global proton pump inhibitors (PPIs) market is witnessing sustained demand due to the rising prevalence of gastroesophageal reflux disease (GERD), peptic ulcers, and acid-related disorders. These conditions are increasingly common owing to sedentary lifestyles, poor dietary habits, and higher stress levels, contributing to the widespread use of PPIs. PPIs, which include both over-the-counter (OTC) and prescription drugs, work by reducing stomach acid production, thereby providing effective relief. Growing healthcare accessibility and the rising availability of generic drugs are further propelling the market’s expansion. Additionally, the shift toward self-medication and OTC options has boosted consumer adoption worldwide.
