Antacid Use in the Elderly: Precautions and Guidelines

Antacid Market Overview, Key Segments

The global antacid market continues to expand steadily as the demand for effective gastrointestinal treatments grows in response to changing lifestyles, rising incidence of acidity, indigestion, and gastroesophageal reflux disease (GERD). Antacids are medications that neutralize stomach acid and are commonly used to relieve heartburn, sour stomach, or acid indigestion. The increasing prevalence of digestive disorders, poor dietary habits, aging population, and growing awareness about gastrointestinal health are driving the growth of the market globally. With over-the-counter (OTC) availability and prescription-based usage, antacids remain a vital part of gastrointestinal therapeutics. Antacid Market Size was estimated at 18.23 (USD Billion) in 2023. The Antacid Market Industry is expected to grow from 18.99 (USD Billion) in 2024 to 24.35 (USD Billion) by 2032

Market Overview

The antacid market is witnessing strong growth and is projected to grow significantly over the forecast period. The increasing burden of gastrointestinal conditions, coupled with a shift in consumer preference toward self-medication and OTC products, is fueling demand. Furthermore, the growing geriatric population and higher consumption of fatty and spicy foods have contributed to rising cases of indigestion and heartburn. Pharmaceutical advancements, such as combination antacid formulations and fast-dissolving tablets, have also broadened the appeal and effectiveness of these medications.

Modern consumers are becoming more health-conscious and are looking for fast-acting relief options that are affordable, accessible, and safe. As a result, pharmaceutical companies are focusing on the development of innovative formulations, including chewable tablets, effervescent tablets, and flavored liquids. With ongoing R&D efforts and expansion into emerging markets, the antacid market is expected to remain resilient in the coming years.

Key Market Segments

The antacid market is broadly segmented based on drug class, formulation, distribution channel, and geography.

By Drug Class:
- Proton Pump Inhibitors (PPIs)
- H2 Antagonists (H2 Blockers)
- Acid Neutralizers (Calcium Carbonate, Magnesium Hydroxide, Aluminum Hydroxide, etc.)
- Combination Drugs
Acid neutralizers dominate the market due to their quick relief action and wide availability over the counter. However, proton pump inhibitors are gaining prominence due to their long-lasting effects in managing chronic acid reflux.
By Formulation:
- Tablets (Chewable & Non-chewable)
- Liquids
- Powders
- Effervescent Tablets
- Gels
Tablets and liquids are the most preferred forms due to ease of use and faster absorption. Innovations like flavored chewables and effervescent antacids are increasingly being favored by younger consumers.
By Distribution Channel:
- Hospital Pharmacies
- Retail Pharmacies
- Online Pharmacies
Retail pharmacies currently lead the distribution segment, especially in developing countries where access to hospitals and clinics can be limited. However, the online pharmacy segment is rapidly growing with the increase in digital healthcare services and e-commerce penetration.
