Antacids Market Report

Antacids Market Size and Share:

The global antacids market size was valued at USD 7.2 Billion in 2024. Looking forward, IMARC Group estimates the market to reach USD 9.7 Billion by 2033, exhibiting a CAGR of 3.4% from 2025-2033. Asia-Pacific currently dominates the market, holding a market share of 42.1% in 2024. The increasing number of patients experiencing gastroesophageal reflux disease (GERD), along with the rising availability of non-prescribed medicines in pharmacies, grocery stores, and online platforms is influencing the antacids market share positively.

Increasing cases of acid reflux, indigestion, and heartburn caused by unhealthy eating habits and rising stress levels are stimulating the market growth. As more people are consuming fast food items, processed meals, and caffeinated beverages, the demand for quick relief through over the counter (OTC) antacids is high. A sedentary lifestyle and irregular meal patterns are also contributing to gastrointestinal discomfort, enabling individuals to seek immediate solutions. Apart from this, the aging population, which is more prone to digestive issues, is supporting the market growth. Additionally, rising awareness among the masses about gastrointestinal health is encouraging early treatment of symptoms, thereby boosting the overall sales.

The United States has emerged as a major region in the antacids market owing to many factors. Increasing health awareness and proactive management of minor health issues are fueling the antacids market growth. High consumption of carbonated drinks and processed food items contributes significantly to digestive discomfort. A stressful lifestyle and irregular eating habits further worsen gastrointestinal issues, leading people to seek immediate relief through antacids. The country’s aging population is also experiencing more frequent digestive problems, driving the demand for quick-acting remedies like antacids. As per industry reports, the count of Americans aged 65 and above is expected to grow to 82 Million by 2050. OTC availability and diverse product formats, such as chewable, tablets, and liquids, add to user convenience. Moreover, easy access through pharmacies, supermarkets, and online platforms is supporting wider reach and item penetration.

Antacids Market Trends:

Rising cases of GERD

The growing cases of GERD are positively influencing the market. As per the report released by the National Library of Medicine in 2022, 783.95 Million people were impacted by GERD in 2019. As the prevalence of GERD is rising due to factors, such as poor diet, sedentary lifestyles, and high obesity rates, people are turning to antacids to get relief from the frequent symptoms of heartburn, acid reflux, and indigestion associated with the condition. The need for accessible and affordable treatments for GERD is fueling the market growth. With the increasing awareness about the long-term effects of untreated GERD, more individuals are utilizing antacids to prevent further complications. Antacids help GERD patients by soothing the esophagus, neutralizing stomach acid, and preventing further irritation.

Growing geriatric population

Rising geriatric population is offering a favorable antacids market outlook. According to the 2022 report from the World Health Organization (WHO), by 2030, 1 in 6 people will be aged 60 years or older. The worldwide number of individuals aged 60 and older will hit 2.1 Billion, an increase from 1.4 Billion in 2020. As the elderly population is growing, the prevalence of age-related digestive issues, such as acid reflux, is rising. Older adults often experience a slower digestive system and weakened stomach acids, making them more prone to these conditions. This has led to a higher demand for antacid products, particularly in tablet and liquid forms, to manage these symptoms. With an expanding elderly population, there is also a greater emphasis on healthcare solutions tailored for senior citizens, boosting the availability and usage of antacids. The trend of longer life expectancy and the desire to maintain a good quality of life are driving the demand for effective and easily accessible antacid items.

Increasing reliance on OTC medicines

Rising reliance on OTC medicines is propelling the market growth. OTC antacids are easily available in pharmacies, grocery stores, and online platforms, making them convenient for individuals seeking relief from heartburn, acid reflux, and indigestion without needing a prescription. This ongoing trend of self-medication is supported by the increasing awareness among people about digestive health and the desire for quick and non-invasive treatments. Additionally, the rising cost of healthcare and long wait times for doctor consultations are making OTC options more appealing. As individuals are becoming more knowledgeable about their health conditions, the demand for OTC antacids is growing. This shift in consumer behavior plays a crucial role in enhancing the sales and availability of antacids across various regions. Non-prescribed remedies, including OTC medicines, are highly preferred in the world to cure mild symptoms, which is catalyzing the demand for antacids. As per the IMARC Group, the global market for OTC drugs is set to attain USD 275.9 Billion by 2032.

Analysis by Drug Class:

• Proton Pump Inhibitors
• H2 Antagonist

• Pro-Motility Agents

Proton pump inhibitors held 32.0% of the market share in 2024. They offer long-lasting and effective relief from acid-related disorders, such as GERD, ulcers, and chronic heartburn.

They are widely prescribed by healthcare professionals due to their proven efficacy in healing the esophagus and preventing acid reflux recurrence. As gastrointestinal disorders have become more common due to unhealthy diets, stress, and sedentary lifestyles, the demand for proton pump inhibitors is high. These drugs are often recommended for long-term treatment, contributing to consistent demand. In response, pharmaceutical firms are developing and launching advanced proton pump inhibitors. For instance, Daewon Pharmaceutical introduced its first proton pump inhibitor medicine in Korea in 2022, known as Escorten. The availability of proton pump inhibitors in both prescription and OTC forms is making them accessible to a broader user base. Moreover, ongoing clinical research and pharmaceutical innovations are improving their safety profile and expanding their indications.
