Subclasses in ATC: A07A - INTESTINAL ANTIINFECTIVES

Market Dynamics and Patent Landscape for ATC Class A07A – Intestinal Anti-infectives

Last updated: January 6, 2026

Summary

The ATC (Anatomical Therapeutic Chemical) classification class A07A encompasses intestinal anti-infectives, primarily targeting infections caused by bacteria, protozoa, and helminths within the gastrointestinal tract. This segment remains critical due to ongoing global burdens of parasitic and bacterial gastrointestinal diseases, particularly in developing regions. The market is characterized by a mix of broad-spectrum agents, targeted anti-protozoal drugs, and novel compounds under patent protection, driven by increasing antimicrobial resistance and expanding therapeutic needs.

Patent activity in this domain reflects a substantial pipeline of innovative molecules aiming to address resistance issues, improve tolerability, and expand indications. Analyzing recent patent filings, market trends, and overall ecosystem dynamics reveals key opportunities and challenges confronting industry stakeholders.


What Are the Key Market Drivers in the A07A Class?

Drivers Details
Global Disease Burden Gastrointestinal infections caused by bacteria (e.g., Vibrio cholerae, Shigella), protozoa (e.g., Giardia lamblia, Entamoeba histolytica), and helminths remain prevalent, especially in low- and middle-income countries (LMICs). WHO estimates over 1.7 billion cases of intestinal parasitic infections annually (WHO, 2017).
Antimicrobial Resistance (AMR) Rising resistance to traditional agents like metronidazole and albendazole compels development of novel drugs with distinct mechanisms. Resistance in Clostridioides difficile and Giardia also heightens need.
Rising Demand for Safer, More Efficacious Drugs Patients and regulators demand improved safety profiles (less toxicity, fewer side effects).
Growth in Diagnostics and Screening Increased detection enhances drug utilization, especially in endemic areas.
Regulatory Facilitation Orphan drug designations, fast-track statuses incentivize innovation for neglected diseases.

Market Size and Forecast

Parameter Data & Projections
Global Market Value (2022) Estimated at $2.1 billion, accounting for antibiotics, anti-protozoal, and anti-helminthic agents (Research and Markets, 2022).
Compound Annual Growth Rate (CAGR) Projected at 4.5%-6% over next five years, driven by emerging markets expansion.
Regional Distribution Leading markets: North America (35%), Europe (25%), Asia-Pacific (30%) which is the fastest-growing due to endemic disease prevalence.
