Antidiarrheals Global Market Report 2025

Antidiarrheal drugs are medications designed to alleviate the symptoms of diarrhea, particularly the frequent passage of watery and loose stools. These drugs can be categorized into three primary groups based on their chemical or functional properties including adsorbents, antimotility agents, and bacterial replacements (probiotics).

The two major classes of antidiarrheal drugs are mucosal protectants and motility-modifying drugs. Mucosal protectants are drugs that serve to protect the stomach's mucosal lining from the corrosive effects of gastric acid and are commonly used in the treatment of peptic ulcers. These agents are available in various forms, including over-the-counter (OTC) medications and prescription drugs, suitable for both adults and children.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report's Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The sudden escalation of U.S. tariffs and the resulting trade tensions in spring 2025 are having a significant impact on the pharmaceutical sector. Companies are grappling with higher costs on imported active pharmaceutical ingredients (APIs), glass vials, and laboratory equipment-many of which have limited alternative sources. Generic drug manufacturers, already operating with minimal profit margins, are particularly affected, with some scaling back production of low-margin medications. Biotech firms are also experiencing delays in clinical trials due to shortages of specialized reagents linked to tariffs. In response, the industry is shifting API production to regions like India and Europe, building up inventory reserves, and advocating for tariff exemptions on essential medicines.

The antidiarrheals market size has grown steadily in recent years. It will grow from $3.93 billion in 2024 to $4.03 billion in 2025 at a compound annual growth rate (CAGR) of 2.5%. The growth in the historic period can be attributed to disease prevalence, global health initiatives, aging population, pharmaceutical innovation, patient awareness.

The antidiarrheals market size is expected to see steady growth in the next few years. It will grow to $4.47 billion in 2029 at a compound annual growth rate (CAGR) of 2.6%. The growth in the forecast period can be attributed to emerging markets, environmental factors, global health challenges, epidemiology and disease burden. Major trends in the forecast period include digital health and telemedicine, patient-centric care, self-care and over-the-counter (otc) products, personalized medicine, biotechnology advancements.

The forecast of 2.6% growth over the next five years reflects a slight reduction of 0.1% from the previous projection. This reduction is primarily due to the impact of tariffs between the US and other countries. Trade tensions could hinder U.S. gastroenterology practices by inflating prices of loperamide and racecadotril produced in Mexico and Poland, resulting in delayed symptom management and higher digestive disorder treatment costs. The effect will also be felt more widely due to reciprocal tariffs and the negative effect on the global economy and trade due to increased trade tensions and restrictions.

The increasing number of diarrhea cases plays a significant role in driving the growth of the antidiarrheal drug market. As reported by UNICEF, diarrhea stands as the second leading cause of death among children under 5 years of age, responsible for claiming the lives of 760,000 children annually. The growing prevalence of diarrhea underscores the heightened demand for antidiarrheal drugs in the market.

The growing prevalence of gastroparesis is anticipated to drive the expansion of the antidiarrheal market. Gastroparesis is a medical condition characterized by the slowing down or delay of food movement from the stomach to the small intestine. This condition can be triggered by various factors, including hypothyroidism, autoimmune diseases, injury to the vagus nerve, and viral stomach infections. Antidiarrheal medications are used to manage gastroparesis and alleviate symptoms such as cramps, bloating, and pressure. For instance, in June 2024, the Cleveland Clinic Journal of Medicine, a US-based non-profit organization, reported that the incidence of gastroparesis in the United States is approximately 6.3 per 100,000 person-years, while in the United Kingdom, it is around 1.9 per 100,000 person-years. The prevalence rate of definite gastroparesis was found to be 21.5 per 100,000 persons. This increasing prevalence of gastroparesis is expected to be a driving factor in the growth of the antidiarrheal market.

Prominent companies operating in the antidiarrheal drug market are actively engaging in mergers and acquisitions with other players in the industry as a strategic approach to expand their market reach and increase their market share. Such mergers and acquisitions allow companies to enhance their market presence, diversify their product portfolios, and gain access to new technologies and capabilities. For example, GlaxoSmithKline's agreement to acquire Novartis AG's 36.5% stake in the consumer healthcare business for $13 billion is a notable move aimed at expanding their presence in the market. This demonstrates a common industry strategy to strengthen and grow their positions through strategic alliances and business combinations.

Major companies in the antidiarrheal drug market are increasingly focusing on developing advanced therapeutic solutions, expanding their scope to treat conditions such as multiple myeloma and mantle cell lymphoma, thereby enhancing patient outcomes and broadening treatment options beyond traditional antidiarrheal uses. The treatment of adult patients with multiple myeloma and mantle cell lymphoma involves targeted therapies designed to address the unique challenges posed by these complex hematological cancers. For example, in June 2022, Hikma Pharmaceuticals PLC, a UK-based pharmaceutical company, launched Bortezomib for Injection, a treatment for multiple myeloma and mantle cell lymphoma available in both subcutaneous and intravenous formulations. The recommended dosage is 1.3 mg/m2, administered twice weekly, with specific guidelines for dose modifications based on toxicity levels. Key safety concerns include the risks of peripheral neuropathy, hypotension, and contraindications against intrathecal administration due to the potential for fatal reactions.
