Drugs and patents in ATC class D06BB

Last updated: July 29, 2025

Introduction

The antiviral medication landscape, classified under ATC code D06BB, continues to evolve rapidly amidst increasing global health threats, including emerging viral infections and resistant strains. This report provides an in-depth analysis of market dynamics and the patent landscape, highlighting strategic opportunities and challenges for industry stakeholders.

Market Overview

Global Antiviral Industry Growth

The global antiviral market was valued at approximately USD 58 billion in 2022 and is projected to grow at a compound annual growth rate (CAGR) of around 4-6% through 2030 (source: ResearchandMarkets). This growth is driven by expanding indications—including influenza, herpes, HIV, hepatitis B and C, and emerging viral diseases such as COVID-19.

Key Drivers

Influenza and Herpes Treatments: Established markets benefiting from consistent demand.
HIV/AIDS Management: Continued innovation in antiretroviral therapies (ARVs) and combination regimens.
Hepatitis C Virus (HCV): The advent of direct-acting antivirals (DAAs) leading to high cure rates.
Emergence of New Viral Threats: COVID-19 accelerated antiviral R&D, especially for novel agents targeting coronaviruses.
Regulatory and Policy Environment: Supportive policies and funding for infectious disease control bolster market expansion.

Market Challenges

Drug Resistance: Viral mutations lead to resistance, necessitating continual drug innovation.
High R&D Costs and Complexity: Developing effective antivirals requires significant investment and sophisticated technology.
Pricing and Accessibility: Cost considerations affect patient access, particularly in low- and middle-income countries.
Regulatory Hurdles: Stringent approval processes slow commercialization of novel agents.

Regulatory Framework & Market Access

Regulatory agencies, including FDA and EMA, have streamlined approval pathways during health emergencies, exemplified by COVID-19 antivirals’ rapid deployment. However, for long-term success, companies must navigate complex regulatory landscapes, which involve detailed clinical data demonstrating safety and efficacy.

Market access strategies increasingly incorporate risk-sharing approaches, and expanding indications for existing antivirals enhance commercial potential.
